Vitamin C is beneficial to your skin in four different ways: 1  It improves your skin by making it firmer and younger looking. Vitamin C is a critical element in the formation of collagen, the protein that keeps your skin looking younger and suppler. 2  It stops premature aging and wrinkling.
1 Helps produce collagen â Collagen binds the cells of our body. 2  Vitamin C serum stimulates the synthesis of collagen in the skin which will give you a tighter, firmer and less sagged feel. 3  It is a good first-step solution to treat the onset of wrinkles. But it is important to note that a vitamin c serum cannot replace your sunscreen. 2  A sunscreen provides the much needed SPF protection by shielding the outer layer of the skin while the vitamin c serum acts as a sun barrier from within the skin.
