How does CSI Vitamin C + 12% Youth Serum work?


Vitamin C + 12% Youth Serum contains 12% vitamin C serum making it a stable and powerful antioxidant that stimulates cell renewal and the production of both collagen and elastin.


Collagen is the main protein found in connective tissue which gives skin structural support. During intrinsic (internal) aging, your skin's ability to produce collagen slows, decreasing firmness in the skin.  Elastin is the substance largely responsible for your skin's suppleness. As time goes on, elastin fibers weaken, causing skin to lose elasticity.  


Vitamin C + 12% Youth Serum also boosts the skin’s natural immune properties, minimizing and repairing damage caused by free radicals, unstable molecules triggered by environmental factors such as the sun's UV rays, smoke and pollutants.


This result is clear, beautiful skin which looks radiant and firm

Easy absorption I like this serum, it is not sticky or heavy. The skin feels nice and smooth after the first use. August 11, 2014
Good I have not seen a big change with this product, but I think it will take time for results. August 2, 2014
Very good product I have been using this product for about 2 weeks and the small lumps, on my face are nearly all gone. They are not acne, not sure what but they are going away. I know it is probably a combination of this CSI C serum and my whole food supplements. This serum goes on kind of feeling thick but after a few minutes it sinks in and is a good primer for makeup. No irritation even after I exfoliate. I use the C first, then sunscreen, then moisturizer, then makeup. Waiting a few seconds for each ingredient to sink into my skin before adding the next element. I really like the results and hope it continues to perform as time goes on. July 20, 2014
Unique feel and performance I really like this serum. Some reviewers have commented that feels oily, however, within 15 minutes it gets fully absorbed and my skin looks dewy, brightened, and even. It behaves opposite of an oily product that stays on top of the skin - after that initial 15 minutes, my skin has no oily residue or shine for the rest of the day. Plus, Vitamin C is super good for both antioxidant properties and encouraging collagen production. Over the years, I've also taken high amounts of Vitamin C orally daily -- at 60, my skin is in great shape with almost no wrinkles, so I figured adding a topical Vitamin C would get me to 70 with still good skin. I use a four step process for this serum: (1) cleanse and tone, (2) apply CSI Vitamin C+12% Youth Serum, (3) wait 15 minutes, (4) apply a light layer of hyaluronic acid (Reviva). After 5 minutes, skin looks and feels great, ready for makeup or just a bare face for the day. July 15, 2014
Excellent product at a great price! Have tried many other vitamin C serums; some very expensive lines. This is my favorite by far; skin glows and I get many compliments on my complexion. I notice a huge difference when I don't use it ~ July 8, 2014
