Does Self-Tanner Protect Your Skin from the Sun? Here's What Science Says

If you’re a fan of a healthy, sun-kissed glow but also serious about protecting your skin, you’ve probably asked yourself: “Does self-tanner offer any protection against the sun?”

It’s a common myth and has often been said that self-tanners are purely cosmetic and provide no real defense against UV rays. But according to Professor Hans Christian Wulff, a Danish skincare expert, self-tanners does actually protect your skin to some extent.

What the Research Really Says About Self-Tan and Sun Protection

In a scientific study referenced by Professor Wulff, researchers tested the effects of self-tanner on hairless mice. After applying self-tanner, the mice were exposed to UV-rays. Contrary to expectations, the mice with self-tan developed skin damage and cancer significantly slower than those without.

Even more impressively, the protective effect of the self-tanner lasted longer than traditional sunscreen in the test conditions.

Says professor Wulff

This finding suggests that while self-tanners are not substitutes for sunscreen, they do contribute to skin defense, especially when used as part of a broader sun protection routine.

Why Skincare Experts Recommend Using Self-Tanner Before Sun Exposure

Skin scientists at Bispebjerg Hospital in Copenhagen now recommend using self-tanner as a complementary form of sun protection. While it shouldn’t replace SPF, applying self-tanner ahead of sun exposure may help your skin build extra resilience.

This is especially important for people with sensitive skin or those who prefer a gradual tan without harmful UV exposure.
