The Answer
We don't stop at cooling
Conventional after-sun products stay on the surface, cooling and hydrating the skin. The DERMA CLASSIC 2-step routine on sale today boosts skin absorption with microneedles, with results confirmed in human application tests by accredited institutions.
STEP 1
Microneedle Patch
Dissolving microneedles pass through the stratum corneum to boost skin absorption of active ingredients. In a human application test, skin absorption rose about 1.9× (+90.4%) versus before use after a single application. The needles dissolve into the skin within 5–15 minutes.

A gel cream built on a liquid-plasma base supplies follow-up ingredients and soothes the skin.
