Numerous products claim to contain beneficial ingredients to "reverse" the signs of aging.  However, it is a fact that the molecular size of most active ingredients prevents them from penetrating the skin's protective outer layers.  As a result, many skincare creams use non-penetrating additives and silicones that merely sit on the surface of the skin to create the illusion of smoother skin without providing long-term nutritive benefits to the living cells under the surface skin layers. 

Sesha is a science-based skin care program dedicated to revealing beautiful skin by feeding and nourishing it. Using proprietary and FDA-approved delivery system (PET™), Sesha products deliver the highest quality antioxidants, botanicals, and vitamins where no other skin care system can - to the skin's regenerative layers. 

PET™ works by increasing the solubility parameter of the skin so when larger-molecule, active ingredients are combined with PET™, they are able to pass between the skin cell barrier to reach the deeper layers of the skin.
