Grapefruit

Grapefruit contains vitamin C, which helps protect the skin against sun damage, aging, and inflammation.

Vitamin C is often used in serums to heal the skin, brighten dark spots, and smooth the skin surface. However, studies also show that an increased intake of vitamin C through foods like grapefruit may help with hyperpigmentation, discoloration, and signs of aging.

Vitamin C helps the body produce more collagen, which has been shown to benefit skin hydration and wrinkles.

Grapefruit also contains citric acid, malic acid, and tartaric acid. These are all different types of alpha-hydroxy acids (AHAs). AHAs are often used in skin care products due to their variety of benefits, including improved skin texture and elasticity.
