Aging is a natural process characterized by accumulating degenerative damages. There are many factors that can accelerate and contribute to the aging process of skin. One of the most notable is caused by free radicals, also known as reactive oxygen species.
Free radicals can be formed by exogenous factors such as ultraviolet (UV) radiation, pollution, tobacco, as well as endogenously. Accumulation of free radicals can cause lipid peroxidation. This is the process by which free radicals “steal” electrons from lipids in cell membranes causing cell damage or even cell death. Free radial formation that causes lipid peroxidation can damage skin cells leading to the appearance of premature aging.
Natural ingredients for skincare has been used traditionally for centuries, and are becoming increasingly popular in more contemporary skincare preparations. Recently, many phytochemicals have demonstrated potent antioxidant effects that may help slow the aging process and extend lifespan of skin by neutralizing free radicals.
