Applying Vitamin C to the skin is 20 times more effective than ingesting it orally. In Tibet during the Tang Dynasty women rubbed the golden-orange berries of the sea buckhorn plant on their faces and hands to fight the outward signs of aging.
Native Americans made a Vitamin C rich paste of rose petals to heal their skin.
Today we realize why these remedies were so trusted by ancient civilizations. When topically applied, Vitamin C provides skin rejuvenating effects by improving collagen synthesis, brightening pigmentation, and protecting cells from free radical damage.
