"I think vitamin C is maybe the number-one, top antiaging ingredient of all time , " says Dr. Dennis Gross, MD. " It's the only ingredient that both directly stimulates fibroblast cells to make collagen and protects the collagen you already have by acting as an antioxidant ."
Vitamin C has become a champion brightener also via it's melanin-disrupting qualities. Historically vitamin C has been difficult to harness, due to it's easy deactivation by exposure to light and air, but the newest formulations piggyback the C in an oil base. Dermatologist Nicholas Perricone, MD has been studying vitamin C since the 80's and states that " with a fat-soluble vitamin C, we can go to all parts of the cell, including the plasma membrane-the most vulnerable part of the cell-and the mitochondria. We can also get much higher levels of vitamin C very quickly into the skin, providing a therapeutic environment for anti-inflammatory activity and building collagen and elastin."
And don't forget it's DNA damage protection from UV rays when applied before sunscreen. A hint: do not mix C with alpha hydroxy acids, they will change the pH and render the C inactive. Check out our list of some of the best vitamin C's on the market.
