Does vitamin C help your skin?
Updated 3 Nov 2026
Short answer
Skin holds a lot of vitamin C, which helps make collagen and helps protect skin from damage by UV light.[1] It is not well known whether creams and serums do more than enough vitamin C from food.[1] In one trial, 30 people used a serum with 10% vitamin C and phytic acid twice a day for 3 months.[2] It faded sun spots more than the same serum without the active parts.[2]
