The Science Behind

WetFilm™ MB is an aliphatic polyester with a polymeric structure specifically designed for water-resistance and clear application on wet skin.

The polymer is a high molecular weight, hydroxyl-functional crosslinked aliphatic polyester. The high molecular weight polyester structure provides a flexible film that translates to even coverage on skin for optimized sun protection. The hydroxyl functionality gives emulsification properties that prevent coalescence of droplets on skin, eliminating the whitening effect often observed with sunscreens applied to wet skin.
