Retinol is pure and active Vitamine A that helps stimulate cell renewal. The cream is further enriched with Vitamines C (to even out the skin's tone) and E (to soften and improve the texture of the skin). I bought in in Holland, in a drugstore, for 25,50 EUR, 30 ml.
This product promises to achieve visibly reduced wrinkles, even tone and improved skin texture within 12 weeks. As this is my first Retinol serum, I am very curious about it, I shall keep you posted :-).
