Blueberries are high antioxidant and phytochemical carriers. These anti oxidants seep in the skin tissue and provide a shield against free radicals by neutralizing them. These free radicals cause a lot of damage to the tissues if not targeted. Blueberries fight early signs of aging and keep lips young, pink and supple. The vitamin C in blueberries helps in strengthening the blood vessels. Weak blood vessels are prone to damage and breakage. These make the lips sensitive and a perfect target for numerous allergies and discoloration. Vitamin C works at the capillary level and provides strength to the vessels beneath the skin surface.
