First impression: I'm newbie in the use of retinol. So I decided to start with a product with a few amount of it and this is perfect because only have 0.1% o f retinol. I'm using this for a few weeks now, I'm loving it! Not irritating or inflammation because of the use. And also have so many soothing and calming ingredients like tocopherol, panthenol, green centella... In a few months I rewrite that if I see a improvement in my skin!!
