Supergoop vs La Roche-Posay vs EltaMD: Best US Travel Sunscreen 2026 (TSA-Ready)

US dermatologists in NYC and LA split three ways on the best travel sunscreen for a two-week international trip in 2026, and the surprising winner on cost per ounce is not the flashy Supergoop, despite marketing budgets that outstrip La Roche-Posay and EltaMD combined on Instagram and Sephora front-of-store real estate. The math on a fluid-ounce basis, which is what actually matters when you are packing a TSA 3-1-1 quart bag for a 14-day trip, tells a different story. So does the derm chair.

The verdict

For a US traveller in 2026, the best travel sunscreen depends on the constraint you are optimising against. Supergoop Unseen Sunscreen SPF 40 is the pick for combination and oily skin under makeup because the invisible gel finish disappears on most skin tones and layers cleanly under foundation. La Roche-Posay Anthelios Melt-In Milk SPF 60 is the pick for full-body high-UV coverage on beach and hiking days at the lowest cost per fluid ounce among the three. EltaMD UV Clear Broad-Spectrum SPF 46 is the pick for acne-prone or rosacea-prone skin because niacinamide, hyaluronic acid, and a lightweight chemistry sit under makeup without triggering breakouts. All three fit inside the TSA 3-1-1 quart bag when bought at 1.7 to 3.4 fluid ounce sizes.

Why US derms disagree in 2026

US dermatologists disagree on the best travel sunscreen because the answer depends on the patient in the chair. An NYC dermatologist working out of a Fifth Avenue office treats a lot of adult acne, post-inflammatory hyperpigmentation, and skin barrier dysfunction. Their travel SPF pick tilts toward products that heal while they shield, which is why EltaMD UV Clear Broad-Spectrum SPF 46 shows up on the wall as the house recommendation. An LA dermatologist practicing in Santa Monica or Beverly Hills sees a lot of outdoor-lifestyle patients, marathon runners, cyclists, and surfers, and the recommendation slides toward high SPF body coverage that holds up under sweat, which is where La Roche-Posay Anthelios Melt-In Milk SPF 60 earns its slot. An aesthetic dermatologist focused on layering under makeup routes patients to Supergoop Unseen Sunscreen SPF 40 because the gel finish sits under foundation without pilling.

The travel context complicates the recommendation further. A 14-day international trip is a face SPF plus a body SPF, not one product. TSA 3-1-1 caps each liquid container at 3.4 fluid ounces, which limits what fits in the quart bag. Cost matters more when you are buying two or three travel bottles instead of one big pump.

What US derms actually recommend for travel

The travel-specific recommendation from most US board-certified dermatologists is a two-product carry: a face SPF that you can reapply over makeup, and a body SPF that survives sweat and swim. That framing collapses the marketing gloss and reveals the honest answer. Supergoop and EltaMD compete for the face slot. La Roche-Posay Anthelios owns the body slot for most travellers because of the price-per-ounce math. Only travellers with specific skin conditions should pay Supergoop or EltaMD prices for body coverage.

The role of FDA sunscreen filter regulation

FDA sunscreen filter regulation shapes what US shoppers can buy at Sephora, Ulta Beauty, Amazon, CVS, and Target. The FDA has approved 16 active sunscreen filters under the Monograph, but only 2 physical filters (zinc oxide and titanium dioxide) and 14 chemical filters are commonly used in US commerce. Newer European filters like Tinosorb S, Tinosorb M, and Mexoryl 400, which appear in La Roche-Posay Anthelios formulations sold in France, are not FDA approved for US sale as of August 2026. That is why the US-formula La Roche-Posay Anthelios feels different from the French-pharmacy version, and why travellers occasionally stock up on the French version abroad.

The role of Hawaii and Palau sunscreen bans

Hawaii's Act 104 (effective 1 January 2021) bans the sale of over-the-counter sunscreens containing oxybenzone or octinoxate. Palau's ban extends to seven ingredients. Aruba, Bonaire, and Cozumel enforce reef-friendly rules to varying degrees. US travellers heading to Maui, Kauai, the Big Island, or Palau should filter their travel sunscreen picks against these bans. Supergoop Unseen Sunscreen passes both. La Roche-Posay Anthelios Melt-In Milk in some US SKUs contains oxybenzone and is not compliant for Hawaii sale; the Anthelios Mineral SPF 50 zinc oxide version is compliant. EltaMD UV Clear contains octinoxate and is not compliant for Hawaii sale; EltaMD UV Pure is compliant. Read the label before packing.

Supergoop Unseen Sunscreen SPF 40: the invisible-finish face SPF

Supergoop Unseen Sunscreen SPF 40 is a 1.7 fluid ounce silicone-gel face SPF that dries invisible on most skin tones and doubles as a makeup primer. The finish is the reason Supergoop dominates Sephora front-of-store: no white cast, no greasy shine, no eye sting. Under foundation, Unseen Sunscreen sits like a primer and does not pill when the shopper layers a tinted moisturiser or a full-coverage foundation on top.

Price at Sephora is around USD 40 for 1.7 fluid ounces, which lands at roughly USD 23.50 per fluid ounce as of August 2026. That is a premium price point relative to any drugstore SPF, and roughly parity with EltaMD UV Clear on a per-ounce basis. Supergoop also sells a 0.68 fluid ounce mini at around USD 20, which lands at roughly USD 29 per fluid ounce, higher on a per-ounce basis but easier to justify for a one-time trip. Activate ShopBack cashback at Sephora, Nordstrom, or Amazon before you check out.

Who Supergoop Unseen is for on travel

Supergoop Unseen is for the face, not the body. It fits combination-to-oily skin, works cleanly under most foundations, and is easy to reapply over makeup with a hand pat. It is not designed for beach coverage or high-UV body use. Do not use Unseen as your only travel SPF; it will not last through a Cancun beach day or a Costa Rica hike.

Where Supergoop Unseen falls short

Water resistance is the shortfall. Supergoop Unseen carries a 40-minute water resistance claim on the FDA label, which is the lower of the two water resistance tiers. It is not a sweat-and-swim sunscreen. In humid destinations like Bangkok, Singapore, Bali, or San Juan, expect to reapply every 90 minutes or layer a mineral SPF powder like Colorescience Sunforgettable on top midday.

How Supergoop Unseen compares under makeup

Under makeup, Unseen has fewer competitors. The gel finish sits under foundation without altering finish, and shoppers can pat additional product over makeup with clean hands or a beauty sponge without smearing the base. La Roche-Posay Anthelios Melt-In Milk pills under some foundations and is designed for body use. EltaMD UV Clear tinted and untinted work under makeup, though the tinted version has a slight peach cast that not all skin tones prefer.

La Roche-Posay Anthelios Melt-In Milk SPF 60: the value body SPF

La Roche-Posay Anthelios Melt-In Milk SPF 60 is the value pick for full-body coverage in 2026. The 5.0 fluid ounce tube at La Roche-Posay US, Amazon, Ulta Beauty, CVS, or Target typically retails between USD 19.99 and 22.99 before promotion, which lands at roughly USD 3.99 to 4.60 per fluid ounce. That is 5 to 6 times cheaper per ounce than Supergoop Unseen or EltaMD UV Clear, and the SPF 60 rating is higher than either.

The formula uses a mix of chemical filters including avobenzone, homosalate, octisalate, and octocrylene. Water resistance is rated 80 minutes on the FDA label, the higher of the two water resistance tiers. The Melt-In Milk texture spreads across a full body surface in under a minute and dries quickly enough that a shopper can dress within 3 to 5 minutes.

Travel-size and full-size La Roche-Posay Anthelios

La Roche-Posay sells a 1.7 fluid ounce Anthelios travel size at around USD 15 to 18, which is TSA 3-1-1 compliant for carry-on. The 3.4 fluid ounce size (around USD 20 to 22) also fits carry-on. The 5.0 fluid ounce full tube does not fit the quart bag and must be checked, but is the cheapest option per ounce for travellers checking a bag anyway. Activate ShopBack cashback at Ulta Beauty, Amazon, or the La Roche-Posay US site before you check out.

Anthelios variants US travellers should know

The Anthelios line has several SKUs and the distinction matters for Hawaii and Palau compliance. Anthelios Melt-In Milk SPF 60 (chemical filters, contains oxybenzone in some SKUs) is not compliant for Hawaii sale in oxybenzone SKUs. Anthelios Mineral SPF 50 (zinc oxide only) is Hawaii compliant. Anthelios UV Correct Face SPF 70 (chemical filters, no oxybenzone) is US bestselling for face and is Hawaii compliant on oxybenzone but check octinoxate labelling. Anthelios AOX Serum SPF 50 layers under makeup and is Hawaii compliant. Read the ingredient panel before packing for Maui, Kauai, or the Big Island.

Where Anthelios falls short

Under some heavy full-coverage foundations, Melt-In Milk pills. It is designed for body, not face-under-makeup layering. For face SPF under makeup, choose Anthelios UV Correct or Anthelios AOX Serum, not Melt-In Milk. The scent is a mild La Roche-Posay pharmacy scent that some travellers find off; it fades within 10 minutes.

EltaMD UV Clear Broad-Spectrum SPF 46: the acne-prone and rosacea pick

EltaMD UV Clear Broad-Spectrum SPF 46 is a 1.7 fluid ounce lightweight face SPF with 9% zinc oxide and 5.5% octinoxate, plus niacinamide, hyaluronic acid, and lactic acid. It is the derm-office wall pick for acne-prone, rosacea-prone, and post-procedure skin because the niacinamide and lactic acid support barrier recovery while the zinc oxide shields.

Price at Dermstore, Amazon, and the EltaMD direct site typically runs USD 41 to 43 for the 1.7 fluid ounce tube, which lands at roughly USD 24 to 25 per fluid ounce. That is the highest per-ounce price among the three, roughly parity with Supergoop Unseen. Sephora and Ulta Beauty typically do not stock EltaMD, so shoppers should activate ShopBack cashback at Amazon or Dermstore before you check out.

Why acne-prone US shoppers choose EltaMD UV Clear

Adult acne responds badly to heavy occlusive sunscreens. Many chemical face SPFs trigger comedonal breakouts. EltaMD UV Clear uses a lightweight zinc oxide chemistry with niacinamide that most acne-prone shoppers tolerate. The tinted version (with iron oxides) doubles as light coverage. The untinted version is invisible on light-to-medium skin tones and can leave a slight white cast on deeper skin tones.

EltaMD UV Clear vs EltaMD UV Pure and UV Physical

For travellers to Hawaii, Palau, or reef-sensitive destinations, EltaMD UV Clear is not compliant because it contains octinoxate. EltaMD UV Pure Broad-Spectrum SPF 47 (pure zinc oxide + titanium dioxide) is compliant. EltaMD UV Physical Broad-Spectrum SPF 41 (tinted pure zinc oxide) is compliant. Read the label; travellers frequently confuse the UV Clear and UV Pure SKUs.

Where EltaMD UV Clear falls short

Cost is the primary shortfall for body use. At USD 24 to 25 per fluid ounce, EltaMD UV Clear is uneconomical for full-body coverage; it is designed as a face SPF. Water resistance is not on the label, so it is a daily wear product, not a beach or pool product. For beach and pool, layer EltaMD UV Clear as the face base and use La Roche-Posay Anthelios Melt-In Milk or a similar water-resistant body SPF over the body.

Cost per ounce and TSA math for a two-week trip

The math on a two-week international trip changes the merchandising picture. Assume one face SPF and one body SPF in the carry-on quart bag, plus one larger body SPF in the checked bag. The face SPF is a 1.7 fluid ounce bottle, the carry-on body SPF is a 3.4 fluid ounce tube, and the checked body SPF is a 5.0 fluid ounce tube.

The Supergoop-and-EltaMD-heavy shopper spends roughly USD 40 on Supergoop Unseen 1.7 fluid ounces, USD 41 to 43 on EltaMD UV Clear 1.7 fluid ounces, USD 20 to 22 on La Roche-Posay Anthelios 3.4 fluid ounces carry-on, and USD 20 to 22 on La Roche-Posay Anthelios 5.0 fluid ounces checked. That is roughly USD 120 to 130 in sunscreen for one traveller. The La Roche-Posay-heavy shopper spends roughly USD 40 on face SPF (choose Supergoop Unseen or EltaMD UV Clear based on skin type) plus USD 40 to 45 on La Roche-Posay Anthelios travel and full sizes. That is roughly USD 80 to 85 in sunscreen for one traveller. Two travellers on a beach trip could see the sunscreen spend swing between USD 160 and USD 260 depending on which of the three brands they lean on. Activate ShopBack cashback at Sephora, Ulta Beauty, Amazon, or Dermstore before checking out to shave that spend down.

TSA 3-1-1 quart bag layout for sunscreen

The TSA 3-1-1 quart bag needs to hold face SPF, body SPF, toothpaste, cleanser, moisturiser, and any other travel liquids. That means the sunscreen slots are limited. A workable layout: one 1.7 fluid ounce face SPF (Supergoop Unseen or EltaMD UV Clear), one 3.4 fluid ounce body SPF (La Roche-Posay Anthelios travel), and one 1.0 fluid ounce lip SPF (Supergoop Play Lip Balm or similar). That leaves quart bag capacity for toothpaste, cleanser, moisturiser, and eye drops.

Checking a bag changes the sunscreen math

Travellers checking a bag can bring the 5.0 fluid ounce La Roche-Posay Anthelios full tube plus a spare travel size in the quart bag. That is the cheapest legal path for a beach-heavy trip because the 5.0 fluid ounce tube at roughly USD 4 per fluid ounce is dramatically cheaper than any 1.7 fluid ounce travel size. Carry-on-only travellers pay a per-ounce premium for the travel-size format regardless of brand.

US shopping channels and cashback stacking

The choice of merchant matters for both price and cashback stacking. Sephora is the reliable channel for Supergoop and typically runs the Sephora Beauty Insider Sale in April and November with 10 to 20% off Rouge, VIB, and Insider tiers. Ulta Beauty is the reliable channel for La Roche-Posay Anthelios and typically runs 21 Days of Beauty in September and March. Dermstore is the reliable channel for EltaMD and typically runs anniversary sales in May with 20% off select brands.

Amazon carries all three brands but grey market risk is real, especially on EltaMD; check the sold by Amazon.com label and avoid third-party sellers with no return address. CVS and Target carry La Roche-Posay Anthelios at competitive shelf prices and are the fallback in a pinch when you cannot wait for shipping.

ShopBack cashback stacking on beauty in the US

Activate ShopBack cashback in the browser extension or the ShopBack app before you check out at Sephora, Ulta Beauty, Amazon, Dermstore, or a partner drugstore. Cashback rates and terms vary by merchant, category, and promotion window, so compare live rates on the ShopBack merchant page before you place the order. Stack cashback with the merchant's own loyalty programme (Sephora Beauty Insider points, Ulta Ultamate Rewards, Amazon Prime Day discounts) for the largest total saving.

Timing the beauty spend on travel sunscreen

The two best US beauty sale windows for travel sunscreen are late April to mid-May (Sephora Beauty Insider Sale, Ulta Beauty spring events, Mother's Day promotions) and early November (Sephora Beauty Insider Sale, Ulta Beauty Cyber Week). Travellers planning a summer trip should stock up in the April to May window. Travellers planning a winter beach trip should stock up in November.

The single biggest travel sunscreen mistake US travellers make is under-application. Correct volume is roughly a nickel-size dab for face and a shot glass (roughly 1.0 fluid ounce) for full body. Under-application halves the labelled SPF value. A well-applied SPF 30 outperforms a poorly applied SPF 60.

What this means in practice

In practice, this means a two-traveller couple booking a 10-day Bali trip in November 2026 should pack one 1.7 fluid ounce Supergoop Unseen or EltaMD UV Clear for face, one 3.4 fluid ounce La Roche-Posay Anthelios travel size for carry-on body, and one 5.0 fluid ounce La Roche-Posay Anthelios full tube in the checked bag. Total sunscreen spend roughly USD 85 to 100 per traveller. Activate ShopBack cashback at Ulta Beauty, Sephora, or Amazon before checking out for the sale window.

A second example: a solo NYC-based professional taking a 5-day work trip to LA in September 2026 with no beach plan should pack one 1.7 fluid ounce EltaMD UV Clear tinted for daily face wear and skip the body SPF entirely (long sleeves, indoor most of the day). Total spend roughly USD 41 to 43 at Dermstore. Activate ShopBack cashback at Dermstore before checking out.

A third example: a family of four booking a Maui trip in June 2026 should stock exclusively Hawaii-compliant SKUs. Supergoop Unseen (oxybenzone-free) for adult face, La Roche-Posay Anthelios Mineral SPF 50 for body, and EltaMD UV Pure or Blue Lizard Australian Sunscreen for the kids. Skip La Roche-Posay Anthelios Melt-In Milk in the oxybenzone SKU and skip EltaMD UV Clear (contains octinoxate). Read the label at point of purchase.

ShopBack cashback is stackable with merchant loyalty tiers and promotional discounts in the US on eligible orders at partner merchants. Cashback rates and terms vary. Check live rates on the ShopBack merchant page for Sephora, Ulta Beauty, Amazon, and Dermstore before you place the order.

When this does NOT apply

• You are undergoing active skincare procedures. Fresh chemical peels, laser resurfacing, and microneedling require dermatologist-directed post-procedure sunscreen, often a mineral zinc oxide formulation not covered here.
• You have known allergies to specific sunscreen filters. Homosalate, oxybenzone, and octinoxate allergies rule out several of the products discussed. Check the ingredient list and patch test.
• You need waterproof-level water resistance. No US OTC sunscreen is legally labelled waterproof; the FDA maximum is 80 minutes water resistance. For extreme water sports, expect to reapply frequently regardless of brand.
• You are travelling only to indoor destinations. A trip that involves no meaningful outdoor time (a business trip with lobby-to-lobby transit) does not require the two-SPF layout. Face SPF alone is enough.
• Your destination bans specific SPF filters. Hawaii, Palau, Aruba, Bonaire, and parts of Mexico ban specific ingredients. Do not assume any US-formulated sunscreen is universally compliant.
• You are pregnant and cautious on chemical filters. Some pregnant travellers prefer zinc oxide and titanium dioxide over chemical filters. Consult your OB and switch to mineral formulations.
• You are packing for a child under 6 months. US pediatric guidance is to avoid direct sun exposure and skip sunscreen entirely on infants under 6 months. Use physical shade and clothing.

Frequently asked questions

What is the best travel sunscreen for a US traveller in 2026?

There is no single best travel sunscreen for every US traveller. Supergoop Unseen Sunscreen SPF 40 is the pick for combination and oily skin under makeup because the invisible gel finish disappears on most skin tones and layers cleanly under foundation. La Roche-Posay Anthelios Melt-In Milk SPF 60 is the pick for full-body high-UV coverage on beach and hiking days because a 5.0 fl oz tube costs roughly USD 3.99 to 4.60 per fluid ounce, well below the Supergoop line. EltaMD UV Clear Broad-Spectrum SPF 46 is the pick for acne-prone or rosacea-prone skin because niacinamide, hyaluronic acid, and a lightweight zinc oxide chemistry sit under makeup without triggering breakouts. All three fit inside the TSA 3-1-1 quart bag when bought at 1.7 to 3.4 fluid ounce sizes. Activate ShopBack cashback at Sephora, Ulta Beauty, or Amazon before you check out to earn cashback on the travel-size purchase.

Which travel sunscreen has the lowest cost per fluid ounce in 2026?

La Roche-Posay Anthelios Melt-In Milk SPF 60 is the lowest cost per fluid ounce among the three flagship products as of August 2026. A 5.0 fl oz tube at La Roche-Posay US, Amazon, or Ulta Beauty typically retails around USD 19.99 to 22.99 before promotion, which lands at roughly USD 3.99 to 4.60 per fluid ounce. Supergoop Unseen Sunscreen SPF 40 in the full 1.7 fl oz size at Sephora retails around USD 40, or about USD 23.50 per fluid ounce. EltaMD UV Clear Broad-Spectrum SPF 46 in the 1.7 fl oz size at Dermstore, Amazon, or the EltaMD site retails around USD 41 to 43, or roughly USD 24 to 25 per fluid ounce. On cost per ounce alone, La Roche-Posay wins by a factor of 5 to 6 despite Supergoop and EltaMD receiving the flashier marketing spend.

How does the TSA 3-1-1 rule apply to sunscreen in a carry-on in 2026?

The TSA 3-1-1 rule applies to sunscreen in a carry-on the same way it applies to any liquid, gel, cream, or paste. Each container must be 3.4 fl oz (100 mL) or smaller, all containers must fit inside one clear quart-size resealable bag, and one bag is allowed per passenger. Supergoop Unseen Sunscreen in the 1.7 fl oz size, La Roche-Posay Anthelios in the 1.7 fl oz travel size, and EltaMD UV Clear in the 1.7 fl oz size all pass 3-1-1. A larger 5.0 fl oz La Roche-Posay Anthelios Melt-In Milk tube does not qualify for the quart bag and must be checked. Medically necessary sunscreen larger than 3.4 fl oz can be declared at the checkpoint under the TSA medical liquids exception, but expect additional screening.

Are Supergoop, La Roche-Posay Anthelios, and EltaMD UV Clear reef safe?

Reef safe is a marketing term with no US federal standard, so treat vendor claims with caution. Hawaii's Act 104 (effective 1 January 2021) bans the sale of over-the-counter sunscreens containing oxybenzone or octinoxate. Palau, Aruba, Bonaire, and parts of Mexico have similar bans. Supergoop Unseen Sunscreen SPF 40 is formulated with avobenzone, homosalate, octisalate, and octocrylene, and does not contain oxybenzone or octinoxate. La Roche-Posay Anthelios Melt-In Milk SPF 60 US formula contains avobenzone, homosalate, octisalate, octocrylene, and oxybenzone in some SKUs, so US travellers heading to Hawaii should swap to the Anthelios Mineral SPF 50 zinc oxide version. EltaMD UV Clear Broad-Spectrum SPF 46 uses 9% zinc oxide and 5.5% octinoxate, which is banned in Hawaii, so travellers to Maui, Kauai, or the Big Island should choose EltaMD UV Pure or another pure-zinc formulation.

Where can a US shopper buy travel-size Supergoop, La Roche-Posay, and EltaMD with cashback in 2026?

US shoppers can buy travel-size Supergoop Unseen Sunscreen at Sephora, Nordstrom, Amazon, and the Supergoop direct site. La Roche-Posay Anthelios is stocked at Ulta Beauty, Amazon, CVS, Target, and the La Roche-Posay US site. EltaMD UV Clear is stocked at Dermstore, Amazon, and the EltaMD direct site (Sephora and Ulta typically do not carry EltaMD). Activate ShopBack cashback in the browser extension or the ShopBack app before you check out at Sephora, Ulta Beauty, or Amazon to earn cashback on the eligible order. Cashback rates and terms vary by merchant and category. Compare live rates on the ShopBack Sephora, Ulta Beauty, and Amazon merchant pages before you place the order.

Why do US dermatologists split three ways on the best travel sunscreen in 2026?

US dermatologists split three ways on the best travel sunscreen because the three products optimise for three different constraints. NYC-based dermatologists focused on adult acne and post-inflammatory hyperpigmentation tend to pick EltaMD UV Clear Broad-Spectrum SPF 46 because niacinamide, hyaluronic acid, and lactic acid support barrier recovery and reduce breakouts. LA-based dermatologists focused on outdoor lifestyles pick La Roche-Posay Anthelios Melt-In Milk SPF 60 because the milk texture spreads across body coverage areas at a lower cost per ounce and holds up under sweat. Aesthetic dermatologists focused on layering under makeup pick Supergoop Unseen Sunscreen SPF 40 because the invisible gel finish sits under foundation without pilling. All three are broad-spectrum, all three are FDA compliant, and all three carry the SPF number on the label.

Will a US traveller need one or two travel sunscreens for a two-week international trip in 2026?

For a two-week international trip, most US dermatologists recommend packing two travel sunscreens: one face SPF for daily use and one body SPF for beach, pool, hiking, or sightseeing days. A 1.7 fl oz Supergoop Unseen Sunscreen SPF 40 or EltaMD UV Clear Broad-Spectrum SPF 46 lasts a face-only user roughly 14 to 21 days at correct application volume (about a nickel-size dab per face). A 3.4 fl oz La Roche-Posay Anthelios travel tube lasts one adult roughly 4 to 6 full body applications at correct volume (about a shot glass per full body). Two travellers going for a week of beach need to decant into 3.4 fl oz carry-on bottles or check the larger 5.0 fl oz tube. Skip skimping: US dermatology guidance is that under-application is the single biggest reason SPF fails in the field.

Do international pharmacies sell Supergoop, La Roche-Posay, or EltaMD?

Availability varies sharply by market. La Roche-Posay Anthelios is stocked in most European, Asian, and Latin American pharmacies (Parapharmacie in France, Watsons and Guardian in Singapore and Hong Kong, Farmacia del Ahorro in Mexico) because La Roche-Posay is a global L'Oreal derm brand. Supergoop is US-heavy and harder to find abroad, though Sephora International, Cult Beauty UK, and Space NK carry select SKUs. EltaMD is the hardest to find internationally because it distributes primarily through US dermatology offices and Dermstore. If you run out mid-trip, La Roche-Posay is the easiest global refill; Supergoop and EltaMD travellers should pack enough for the full trip.

Should a US traveller buy travel sunscreen at Sephora, Ulta Beauty, Amazon, or a drugstore in 2026?

The choice depends on the product and the promotion window. Sephora is the most reliable channel for Supergoop travel-size SKUs and typically runs a Sephora Beauty Insider Sale in April and November with 10 to 20% off Rouge, VIB, and Insider tiers. Ulta Beauty is the most reliable channel for La Roche-Posay Anthelios and typically runs 21 Days of Beauty in September and March with rotating daily deals. Amazon carries all three brands with variable pricing and third-party seller risk (check the sold by Amazon.com label to avoid grey market). CVS and Target carry La Roche-Posay Anthelios at competitive shelf prices, especially during back-to-school and summer sales. Activate ShopBack cashback in the browser extension or the ShopBack app at Sephora, Ulta Beauty, or Amazon before you check out.

Between Supergoop Unseen, La Roche-Posay Anthelios, and EltaMD UV Clear, which lasts longest in humid destinations?

In humid tropical destinations (Bangkok, Singapore, Bali, Cancun, San Juan), water resistance and rewear are the constraints. La Roche-Posay Anthelios Melt-In Milk SPF 60 carries a water resistance claim of 80 minutes on the FDA label and holds up on sweat-heavy sightseeing days. Supergoop Unseen Sunscreen SPF 40 carries a lower water resistance claim of 40 minutes and is not designed as a primary water-resistant product; it works better as a daily face SPF under makeup. EltaMD UV Clear Broad-Spectrum SPF 46 is not marketed as water resistant on the label; treat it as a face-only daily product. For a humid beach or pool day, layer La Roche-Posay Anthelios Melt-In Milk on the body and reapply every 80 minutes, and use Supergoop or EltaMD as the base face SPF with a mineral powder touch-up midday.

Key takeaways and next steps

• Supergoop Unseen SPF 40 wins for face under makeup; La Roche-Posay Anthelios Melt-In Milk SPF 60 wins on cost per ounce for body; EltaMD UV Clear SPF 46 wins for acne-prone and rosacea skin
