This one right here - my holy grail.
Bought it with the mindset that I would use it once a week, as a deep moisturizer treatment, ended up using it almost every night.
I do have an oily T-zone but so far, no breakouts. If I do get some, I'll stop using it so frequently but I'm still going to try to find a way to insert it on my routine now and then, because seriously, the skin is SO soft next morning. I never seen it like this! Not only soft and supple, the colorations seems more homogenous. I have tried going to bed with other night creams (including a cream from Bioderma) and never woke up as hydrated as when I use this product.
I also like that this is not really as heavy as a mask. It really feels more like a cream and it spreads easily and absorbs fast.
