Osmosis Skincare Catalyst AC 11 DNA Repair C Serum

Key ingredients:

Ascorbic Acid (L) (6%): The antioxidant activity of vitamin C protects against UV-induced damage caused by free radicals. Vitamin C aids in collagen production which is vital in reducing the signs of premature aging. Vitamin C also increases the formation of elastin, which thickens, protects, and heals skin cells.

AC-11: This patented formula stimulates collagen production, which is essential for soft and supple skin. AC-11 also heals and protects the skin from everyday elements, while decreasing inflammation at the same time.

Alpha- Ketoglutarate: This is necessary for binding proteins to repair DNA in order to create collagen, which is essential in the production of energy for our cells.

Cysteine: This is a basic building block of the antioxidant glutathione, the human body's most important antioxidant. It helps reduce the appearance of blemishes, age spots, and even wrinkles, giving your skin a natural glow that is the result of naturally healthy skin cells. It also helps the skin defend itself against sun damage.

    We all know the importance of Vitamin C in skin care now days- Vitamin C helps protect and product collagen and there for helps fight the signs of aging!

    L-Ascorbic Acid is a slow release version of vitamin C that will realeas its self into the cells over a period of time as opposed to putting a serum on and your skin maybe being overwhelmed by it this will sync up with your skins natural intake processes and work to realeas as the skin is ready for its next dose of vitamins!

    It has a sophisticated formula but mainly it’s vitamin C which is incredibly important anti-oxidant and fighter with free radicals. I am using Clear as well after applying this serum – it becomes even more effective. The results are incredible!!!

    I am a product junkie, have tried so many prestige lines and this trumps all. I had a recommendation to the Osmosis line, I loved the line but this was a gem. It changes my skin, healthy glowing. Reduces lines, brown spots and scarring. It as close to a miracle serum as they get. It takes a few months to see big results. The results are permanent. You just need to maintain after. A bottle lasts me approx 3 months.
