Jan Marini Skin Research C-ESTA^® Serum containing DAE Complex is the culmination of years of intensive medical research that has resulted in the first stabilized form of lipid soluble topically applied Vitamin C in a patented delivery vehicle, combined with other essential factors. Studies show C-ESTA is able to create conditions in the skin that enable dramatic rejuvenation. Within a short period of time the skin's texture will begin to appear smoother and more supple. With continued use, the skin will appear measurably firmer, more resilient, and facial contours will appear tighter and more defined. Deeper lines will appear far less pronounced, skin pigment will look more even-toned and the skin will appear noticeable younger and healthier.
