The Science Behind

LexFilm™ Sun Natural MB is an aliphatic polyester with a polymeric structure specifically designed for water-resistance and flexible film formation on skin.

This polymer is has a broad molecular weight distribution and high degree of C8 acyl substitution. These features enable a pourable, liquid format and a flexible film, which translates to even coverage on skin for optimized sun protection. The flexibility of polymer film also provides a cushiony skin feel. The combination of a hydrophobic polymer backbone with C8 acyl end groups also results in outstanding water resistance.
