This is my first product with fermented ingredients and I wasn't sure if my skin would react badly to it. I'm very relieved my skin likes this and I've been using it every night for about a month. What I'm most impressed with is the texture. It's pretty thick for a toner or an essence but the finish is not sticky at all but very smooth and it leaves your face feeling plump and full of nutrients. I think I'll either repurchase this or I try the no.3 serum.
