Vitamin C is not only important to boost your immune system while in quarantine but also to improve your skin. It is an essential nutrient required for the growth and repair of tissues in all parts of the body, including the skin, but we cannot produce it on our own. The powerful antioxidant is found naturally in fruits and vegetables and commonly produced synthetically in skincare products, such as moisturizers, toners, and, most often, serums.
Vitamin C is shown to be effective in the following areas:
- Protects against environmental stressors.
- Promotes collagen production.
- Lightens brown spots.
HOW TO USE:
While highly beneficial, Vitamin C does not easily penetrate the skin’s barrier. To be effective, it must be in a concentration of at least 10%, and if adding to another product like a moisturizer, the pH of whatever you’re adding it to must be acidic to allow for absorption.
Vitamin C works well with complementing antioxidants like, vitamin E, and ferulic acid but does work well with benzoyl peroxide, which can oxidize it and make it useless and is temperamental when combined with other acids and retinol.
Depending on the form (e.g serum, powder, mask, etc), Vitamin C is very reactive and easily loses its antioxidant properties when exposed to heat, light, air, and other chemicals. Make sure the product is air-tight after use and stored in a cool, dark environment. If it turns brown, toss it!
