AHC Premier Collagen Serum

These days, when the air is dry, you really need a separate serum like this AHC Premier Collagen T3 Density Serum for skin elasticity and hydration. Since it is a collagen serum, I feel like it covers up skin sagging to some extent after using it for a while—though maybe it's just my imagination. I am sensitive to scents, but I like that the fragrance isn't too strong. However, it is a bit inconvenient that the gold coating on the pump part of the case peels off every time I open and close the lid. I hope this gets improved...
