What does vitamin C do for skin? A guide to its benefits
What is vitamin C in skincare?
Vitamin C is an antioxidant and several different forms are used in skincare products like the best vitamin C serums. Pure vitamin C is known as L-ascorbic acid and often recommended as one of the most stable forms.
However, derivatives of vitamin C are also commonly used and, depending on the concentration can be a little gentler on sensitive skin. These include ascorbyl glucoside and ascorbyl palmitate, for example.
What are the benefits of vitamin C for skin?
The reason why this ingredient is so well-loved is because there are several different skincare benefits on vitamin C’s impressive CV. First and foremost, because it’s an antioxidant, it offers some protection against environmental aggressors like free radicals, which results in oxidative stress that damages our skin (think fine lines, dullness, etc).
It also has a reputation for evening out the appearance of one’s skin. “Vitamin C is known for its ability to brighten the skin and improve overall complexion,” says Dr Aiza Jamil, consultant dermatologist at sk:n Clinics. “It inhibits melanin production, helping to fade dark spots, hyperpigmentation, and uneven skin tone.”
But its benefits don’t stop there. “Aside from brightening the skin and reducing the appearance of dark spots and hyperpigmentation, vitamin C also helps in collagen synthesis, which promotes skin elasticity and firmness,” adds Dr Ifeoma Ejikeme, medical consultant, skin expert and founder of The Adonia Medical Clinic.
