Aging skin is one of the most common skin concerns, affecting everyone at some point in their lives. Environmental factors and cellular metabolism produce DNA-damaging free radicals, resulting in skin cells that are no longer able to function at their peak. This accumulated cell degradation, along with repeated expressions, increased dryness and other factors all contribute to wrinkling and other signs of aging. iS Clinical products for aging skin address the underlying causes of these wrinkles, protect the skin from further damage, exfoliate for reduced fine lines and increased brightness, and restore vital hydration for a more firmed complexion.
