#Peptide for #PrepPair The 6 Peptide Skin Booster Serum
Customer reviews
Softened skin and helped clear out clogged pores. very light serum and works well with other products like the snail mucin serum and vitamin c 23
— Yuanzheng C.
This leaves my skin feeling so soft! I use it along with my vitamin C serum and it really does boost the benefits of both! My skin also appears brighter.
— Suzette J.
My skin dries through the day and this definitely helps to keep me dewy but not shiny. I use it before the niacinamide booster, snail mucin, then the hyaluronic acid face lotion.
— Jaime C.
I’ve been using it with the snail line along with the niacinimide and VitC 23 serums and my skin feels as smooth as a baby’s bottom lol.
— Princess E.
I like following it with the snail mucin and then moisturizer. I use CosRX products exclusively now and my skin has never been better.
