Surfing Skincare: 3 Myths Busted for 2026

I see a ton of bad advice going around about how to take care of your skin while surfing in Costa Rica. From what sunscreens actually work to what to do after your session, a lot of the common “wisdom” is just flat-out wrong and will do more harm than good.

Myth 1: Any SPF 50 sunscreen offers complete protection for hours.

This one is a really common and dangerous myth. An SPF 50 sunscreen is great, but it doesn’t block 100% of UVB rays, and it definitely doesn’t last forever, especially when you’re surfing. The FDA in the US says to reapply at least every two hours, and even more often if you’re swimming or sweating, no matter what the SPF or water-resistance label claims. For anyone surfing in the intense Costa Rican sun at spots like Playa Hermosa or Santa Teresa, that reapplication is non-negotiable. So why do the labels lie? Most “water-resistant” sunscreens are only tested for 40 or 80 minutes in calm water, not for hours of getting pummeled by waves. Think about it: the friction from your board and the constant wash of saltwater will break that sunscreen down way faster than the label suggests, and that’s before you even touch a towel. I’ve seen so many people get absolutely fried because they thought one application of “waterproof” SPF 50 in the morning would last them a four-hour session. It won’t. If you want real protection from both UVA and UVB rays, a broad-spectrum, mineral-based sunscreen with zinc oxide or titanium dioxide is just better. These create a physical block on your skin that reflects UV rays, a different mechanism from chemical filters which absorb them. The American Academy of Dermatology Association (AAD) points out that mineral sunscreens are gentle and start working the second you put them on, which is perfect for active people.

Myth 2: Tanning is a sign of healthy, sun-kissed skin.

Let’s be clear: a tan isn’t a sign of health, and the idea of a “base tan” protecting you is completely wrong. A tan is literally evidence of DNA damage to your skin cells as they react to harmful ultraviolet (UV) radiation. When UV rays hit your skin, they tell your melanocytes to pump out more melanin, which is what makes your skin darker. It’s your body’s desperate attempt to shield itself from more damage. The World Health Organization (WHO) is blunt about it: there is no such thing as a “healthy tan,” and any tan, from the sun or a tanning bed, jacks up your risk for skin cancer, including melanoma. That whole “base tan” idea is especially bad. A tan might give you a tiny bit of protection, maybe an SPF of 2-4, but that’s nowhere near enough to stop sun damage. Relying on a base tan is like trying to stop a hurricane with a t-shirt. It offers almost zero real defense. All that sun exposure, even if you don’t burn, leads to premature aging like wrinkles, fine lines, and sunspots. If you’re out on the Costa Rican coast, whether it’s Guanacaste or the Caribbean side, real skin health means protecting the skin you have, not chasing a tan.

Myth 3: You don’t need after-sun care if you didn’t get burned.

Even if you don’t have a visible sunburn, your skin takes a beating from the sun, salt, and wind out there. Thinking you only need after-sun care when you’re red and peeling completely misses the point about what those elements do to your skin. Saltwater can feel great, but it also strips your skin’s natural moisture barrier, leaving it dry, irritated, and vulnerable. The wind makes that dehydration even worse, especially in a humid but breezy place like coastal Costa Rica. Good post-surf skincare is all about getting moisture back in, calming down inflammation, and fixing your skin’s barrier. The first thing you should do after leaving the ocean is take a freshwater shower to get all the salt and sand off. Right after, while your skin is still damp, slather on a thick, emollient moisturizer to lock in that hydration. Look for ingredients like hyaluronic acid, ceramides, or glycerin, which are fantastic for pulling moisture into the skin and beefing up its protective barrier. Antioxidants like Vitamin E and green tea extract also help neutralize the free radicals created by the sun. If you skip this, you’re setting yourself up for skin that’s always dry and dull, and it’ll age faster, even if you never get a bad burn. It’s like a cool-down for your skin after a tough workout.

Myth 4: Drinking water is enough to stay hydrated for skin health.

Drinking water is critical, but it’s often not enough by itself to keep your skin hydrated when you’re surfing hard in the sun. Between the workout, the sweating, and all the salt and sun, your body is screaming for a type of hydration that plain water just can’t deliver on its own. You lose important minerals like sodium, potassium, and magnesium through sweat, and these electrolytes are what actually manage hydration in your cells. Without enough electrolytes, your body can’t absorb and use that water properly, which leads to cellular dehydration and skin that feels dry, tight, and looks less plump. For anyone spending hours in the water, adding electrolyte-rich beverages is a smart move. Coconut water, which is everywhere in Costa Rica, is a great natural source. You can also use sports drinks or electrolyte tablets mixed into your water. You need to make sure that water is getting into your cells and staying there. That internal balance is what directly affects your skin’s ability to heal and produce collagen, which you need to fight off all the environmental stress.

Myth 5: You should exfoliate aggressively to remove sun-damaged skin.

Scrubbing your face raw after being in the sun is a terrible idea, especially if your skin is already feeling sensitive. People get this wrong because they want to scrub off the sun damage and get to the “fresh” skin underneath fast. But your sun-exposed skin is already vulnerable. Its natural barrier is already weak, and there’s probably some inflammation going on even if you don’t see a burn. Using a harsh scrub or a strong chemical exfoliant (like a high-percentage AHA or BHA) at this point will just cause more irritation and inflammation, potentially wrecking that delicate barrier. Your focus should be on gentle renewal and repair. If your skin isn’t burned, you could try a very mild enzyme exfoliant or a low-strength chemical exfoliant (like lactic acid) once it feels totally back to normal, but use it sparingly. You need to support your skin’s own healing process with lots of hydration and calming ingredients. Things like aloe vera, oat extract, and chamomile are great for calming irritated skin. If you’re surfing all the time, giving your skin a break to recover between sessions and focusing on barrier repair is what will give you healthier, tougher skin in the long run.

Myth 6: Facial waxing is fine right before a surf trip.

Getting your face waxed right before a surf trip to Costa Rica is asking for trouble. A lot of people do it because they think it makes sunscreen go on better or they just like the look, but they forget how sensitive and raw freshly waxed skin is. Waxing doesn’t just pull out hair. It rips off the top layer of your skin, leaving it exposed, easily irritated, and way more likely to get sun damage. Your skin’s protective barrier is shot, and it’s totally unprepared for the assault of intense UV, saltwater, and wind. If you’re going to be surfing, schedule your waxing at least 7-10 days before you’ll be in the sun. This gives your skin enough time to actually heal, rebuild its natural barrier, and for that redness and sensitivity to go away. Make sure to moisturize diligently and be gentle with it during that healing time. Putting sunscreen on freshly waxed skin can sting like crazy, and because it’s so sensitive, even a little sun can cause dark spots (hyperpigmentation) or a nasty burn. Your skin’s health is way more important than being hair-free for a few days when you’re about to face that kind of sun. Enjoying Costa Rica’s surf and sun without wrecking your skin for the long haul just means being smart and consistent. Ditch these common myths, adopt practices that actually work, and you can enjoy the waves without compromising your skin.
