Phyllanthus emblica (amalaki) also known as Indian gooseberry, is a plant used since ancient times in Ayurvedic medicine for different properties: adaptogenic, anti-aging, anti-inflammatory. It is a rich food source of natural vitamin C, essential for the formation of collagen and for the integrity of connective tissue, minerals and amino acids and contains numerous phenolic compounds with antioxidant action. Amalaki extract protects human dermal fibroblasts against oxidative stress and is therefore useful for natural skin care. In a recent study the effects of amalaki extract on human skin fibroblasts were evaluated, in particular for the production of procollagen and matrix metalloproteinases. Amalaki has induced the production of procollagene, making itself suitable in cosmetology in anti-aging products, for sun protection and for general skin care. It acts as a cofactor in the reaction of hydroxylation of the proline and lysine amino acids with consequent stabilization of the collagen. Another study suggests that amalaki extract effectively inhibits photoblocking induced by UVB rays in human cutaneous fibroblast through the strong scavenging capacity of ROS
