Can You Repair Your Skin From Sun Damage? Here's What Experts Have To Say

If you could only have one skin care product for the rest of your days, what would it be? A pretty common answer, especially from skin care professionals, would likely be sunscreen. While chemical exfoliants, face masks, and serums of all kinds are fun and great for extra care, SPF might just be the most essential.

This is because it's the only product that can protect your skin from sun damage, something that can trigger all sorts of negative effects on the skin—some of which you'd look to those extra products to treat.

So priority No. 1 is always prevention. But even among the most diligent skin care devotees, sun care slip-ups do happen—which may leave some wondering: Are there any additional steps that can actually reverse the damage done?

Before we get into whether or not you can repair skin damage from the sun, let's first be clear about what's happening below the surface. "The DNA in skin cells gets damaged when the skin is unprotected and exposed to UVA and UVB radiation from the sun," explains Jodi LoGerfo, DNP, who is a doctor of nursing practice and a family nurse practitioner certified in family medicine and dermatology.

Jodi reiterates, "It is important to be reminded that UV radiation is a proven human carcinogen1. UV radiation results in basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) of the skin; both of these types of cancers frequently develop on sun-exposed areas of skin."

Overall, you can't repair sun damage completely. However, there are certain topical products and procedures that can be done to better the visual effects of sun damage, says board-certified dermatologist Rebecca Marcus, M.D.

"Topical retinoids are useful in repairing photodamage (damage to the skin caused by UV radiation)," Marcus explains. Tretinoin2 specifically has been studied and used for this purpose, in addition to treating other skin conditions like moderate acne and naturally occurring fine lines. 

As far as DNA damage caused by sun exposure, the options are limited. However, recent developments have shown promising results. "Another option for treatment of DNA damage caused by the sun is an enzyme called photolyase3," Marcus says. "This enzyme is activated by UV radiation and works to repair previously acquired UV-induced DNA damage. It is not innate to humans but can be found commercially in ISDIN Eryfotona Actinica." 

For many reasons, avoiding UV exposure completely is just unrealistic. In fact, as Marcus says, it may be dangerous to your health, skin not included. "Avoiding sun exposure altogether would cause modifications to lifestyle that might impact mental health," she says. 

A single layer of SPF won't suffice for those long days in the sun. As most dermatologists preach, "I wholeheartedly endorse daily application of broad spectrum SPF 30 or higher, with reapplication every two hours, and more frequently when swimming or sweating," Marcus says. 

Topical antioxidants (think vitamin C, CoQ10, etc.) can provide a layer of protection4 against UV damage. "While it is not classified as SPF, it does increase the skin's resistance to the sun by a little bit and is an excellent choice as a base layer before sunscreen," Marcus says. 

While hours spent in the sun may result in a bronzy glow, that's not the only road to a beautiful tan. In fact, it's one of the more dangerous routes to take. Instead, get your sun-kissed look from alternative tanning methods like self-tanner. 

"Keeping skin well moisturized will help to soothe and repair some of the immediate effects of sunburn such as peeling, pain, and itching," Marcus says. Be mindful of which products you use, as anything with chemical exfoliants will only make the burn more uncomfortable and irritated.
