This is great product, been using it for couple years now.

Best retinol on the market in my opinion; I visibly see my finelines dissapear after using it for a few times (I'm 36) I've recommended it to all my friend and not a single person had a negative reaction to it; I love all Drunk Elephant but if I hat to choose one, I'd choose this retinol;

This is the most effective retinol that I have ever used! 

I really love this retinol specially in winter. It's so hydrating and moisturizing that I don't even need to put moisturizer after.

I have combination skin, chose this product on the advice of friends. I like the effect, after a month of using my pores minimised, as a result I don’t have problems with acne and overproduction of sebum. A good looking face skin, more contoured. I’ll definitely buy it again.  Please, note that I’m a frequent client of an aesthetician, so we combine seasonal professional peelings and retinol treatment. I believe only in a complex care, so you can appreciate the formula of DE even more
