What Vitamin C Products Do
Vitamin C serums and creams deliver L-ascorbic acid or derivatives to the skin. They support collagen production and help protect against surface oxidation. Dermatologists often recommend them for dullness and uneven tone.
Who Benefits From Vitamin C Products
Most adults with normal, dry, or combination skin can use vitamin C products. They are commonly chosen for visible signs of aging and post-acne marks. People with very sensitive skin should patch-test first.
How to Choose and Use Vitamin C Products
Look for stable forms like L-ascorbic acid, ascorbyl glucoside, or tetrahexyldecyl ascorbate. Check packaging for opaque, airless bottles that limit air and light exposure. Apply a small amount to clean skin in the morning, then follow with sunscreen.
