Does 20-year-old ZA work well?

I am 20, too. I just saved enough money to buy a bottle of ZA yellow milk (revitalizing skin) a few days ago, and I feel-very good! ! ! Hehe, maybe I haven't used any high-end products (still a poor student ~). My classmate and I bought it together. She bought white milk, which is also very good. Ok, let me be specific: yellow milk: I have mixed skin, acne pits on my face and dark yellow skin. Ba recommended me to use yellow milk, saying it could improve my skin problems. I feel very refreshing and comfortable after using it. It's not oily at all, but it's moist. White milk: My classmate has neutral skin, with many spots on his face and always red cheeks. Ba said it was because of poor circulation and recommended her to use white milk. She just put on a little oil, but it soon disappeared-it was all absorbed. Then it's very comfortable and moist ~ Hehe ~ It's really recommended ~
