According to a study conducted by Dermatologists in Copenhagen, Denmark, layering sunscreen boosts the effects of the product. They found that when sunscreen was applied several times a day, it accumulated on the skin and offered protection that stayed, even days later.
Doctors put SPF on volunteers either once or three times daily for five days then photo-tested their skin. Results showed that those who received repeat applications had more sunscreen particles on the skin on day five (even after bathing) versus those who got a single daily application.
Given these findings, consider layering on SPF sunscreen regularly – especially before going out, to provide extra protection from sunburn and skin damage. In fact, this does not differ from the instructions found on most sunscreen products – they typically recommend applying sunscreen 20 minutes before going outside. The trick is to reapply throughout the day to ensure protection and maintain healthy skin.
