Efficacy of cream-based novel formulations of hyaluronic acid of different molecular weights in anti-wrinkle treatment.

Abstract

Topical application of all 0.1% HA formulations used in this study led to significant improvement in skin hydration and elasticity. Application of low-molecular-weight (LMW) HA was associated with significant reduction of wrinkle depth, which may be due to better penetration abilities of LMW HA.
