This new ester developed by Contipro, with very good skin penetration, is active at very low doses and visibly improves skin that has been mistreated by age and the wearing of masks in times of pandemic.

Hyaluronic acid, here of low molecular weight (10-15 kDA), is a recognized moisturizer that penetrates easily into the skin. It helps repair the skin barrier, activates collagen synthesis, and also has anti-aging and anti-inflammatory properties.
HyRetin is an amphiphilic molecule (it is composed of hydrophilic parts from hyaluronic acid and hydrophobic …
