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]
