Hydrated skin improves your skin barrier; Your skin barrier helps protect against irritants and bacteria.
Glycerin has also been found to have antimicrobial and antiviral properties. Due to these properties, glycerin is often used in wound and burn treatments.

Very good and gentle retinol serum
My retinol journey began with this gentle serum with a concentration of 0.3% retinol: 0.1% pure retinol combined with 0.2% retinol palmitate that ensures gradual release of the active ingredients. It din't irritate my skin or cause any major break-outs, just some slight purging in the beginning, but that is concidered a normal reaktion that fades as soon as the skin gets used to it. I recommend it for retinol beginners and people with sensitive skin. [Edited]
