Summary
This moisturizer contains beneficial ingredients like glycerin and hydrolyzed hyaluronic acid, which are excellent for skin hydration and maintaining the moisture barrier. However, the presence of alcohol denat, which can be drying and irritating, and parfum, which may cause allergic reactions, detracts from its overall safety profile. The inclusion of PEG compounds and acrylamide copolymers also indicates a moderate level of processing, which affects the product's rating.
