seshaGet it with Sesha Skin Therapy. This skin therapy stands apart from the others because of their patented delivery system, known at PET. “P.E.T.® It works by solubilizing the active ingredients and temporarily modifying the permeability of the skin. Therefore, when large-molecule active ingredients are combined with P.E.T.®, they are able to pass through the skin cell barrier to reach the deeper layers below the epidermis.” I have been using their clinical line, and I can’t wait to try more. So far the eye cream is my favorite. I also love the thin consistency of the serums and day moisturizer with spf.  So get with this science based skin care system, and feel free to consult with a hot professor….
