  • Ascorbyl Glucoside

    Ascorbyl Glucoside is one of the most stable Vitmain C derivatives, and in-vitro studies have shown that it can penetrate the dermis to give all the amazing benefits your skin requires. In-vitro studies also show that after Ascorbyl Glucoside is absorbed into the skin it is converted to pure Vitamin C. It also shows all the three anti-aging benefits (antioxidant protection + collagen boosting + fading hyperpigmentation) that pure vitamin C does.

  • Ascorbyl Tetraisopalmitate

    Ascorbyl Tetraisopalmitate is an oil-soluble or lipid-soluble tetra ester derivative of Vitamin C (Ascorbic Acid). This derivative in its natural state is easily absorbed through the skin barrier and is not eliminated through aquaporins (water absorption channels in cells). This ensures faster percutaneous absorption than other forms of Vitamin C owing to its lipid solubility. This also has lower irritancy potential, improves hyperpigmentation and increases Trans Epidermal Water Loss. Other observed benefits are increased skin elasticity and visible improvement in skin texture and wrinkles.

  • Ceramides(Ceramide NP, Ceramide NS, Ceramide AS, Ceramide AP, Ceramide EOP)

    Ceramides are lipids that are found in high concentrations in the uppermost layers of skin. One of the best ways to understand how ceramides function is to imagine your stratum corneum (the outermost layer of your skin) to be made up of bricks and mortar. The skin cells are essentially the brick, and the lipids are in between, and that’s what we call the mortar. Without the mortar, the skin barrier will be compromised. Ceramides help reinforce the skin barrier by forming a protective layer that prevents water loss and protects against environmental stressors — giving you plumper, smoother, firmer-feeling skin with fewer visible lines and wrinkles.  

  • Cetearyl Olivate
