How I Match the Serum to My Skin Type
If my skin feels dry, I choose a serum with hydrating ingredients like hyaluronic acid. If my skin is oily, I prefer a lightweight, non-greasy formula. For sensitive skin, I look for a gentler vitamin C derivative instead of a very strong formula.
How I Use It for Best Results
