What Is a Vitamin C Serum?

A Vitamin C serum is a concentrated skincare treatment formulated with vitamin C and other antioxidant ingredients to help brighten the complexion, improve the appearance of uneven skin tone, and protect the skin from environmental stressors.

Vitamin C is one of the most researched skincare ingredients and plays an important role in supporting collagen production while helping reduce the visible signs of aging caused by sun exposure and free radicals.sRegular use of a high-quality Vitamin C serum may help improve skin radiance, reduce the appearance of fine lines, and promote healthier-looking skin.

Consistent daily use may result in brighter, healthier-looking skin.
