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

  • Brighten the look of skin

good ingredients I do like simplicity of the ingredients. Applying product--your skin feel instantly warm. I would not say I am wowed by this product. Probably someone applying it every day for a year would notice difference. I think this serum probably works in combo with something else--I did not find what so far:) May 28, 2015
Good product - great price I like to use 7-8 drops on my face after showering every morning. Similar (or same) product has been available from other sources but none beat Vitacost! Thanks! May 28, 2015
Product is great as a serum I use this everyday before my moisturizer and it seems to give me skin a nice glow without drying or irritating it. April 24, 2015
Great value & addition to my skin care I am a review reader & appreciate the time & truthfulness of reviewers here on how could I not give this a chance? Hitting my mid-40's, I'm beginning to see some sagginess, and lines under my eyes...but the most annoying of all are the enlarging pores (where did these holes come from???) and the discolorations that normally would not linger so long. A vitamin c serum was highly tauted to help...but hard to choose to add to the other new serums & products I've been trying. This brand, being made of just 2 ingredients seemed a great choice, as not to over-do it. So far, I am noticing smoother & more toned skin, along with a nice evening of complexion. I do think this product makes my skin a bit red after applying lightly (first, after cleansing) but this seems to subside, and is not irritating or makes me break out. As a hint, due to the sensitive nature of vitamin C serums, I put the majority of the product in a clean, small amber glass bottle in my refrigerator to store, while using small amounts at a time from the container here, in my bathroom. This should help improve the integrity and strength of the serum over time...that is, until I run out & run back to Vitacost for more! Also, I've read that it can be tricky using vitamin c with niacinimide serums due to the pH levels, so I am careful to use these products separately. Choosing products and brands can be hard on us gals, especially with the amount of money that we shell out thinking more expensive is better...yet to me, looking at the quality of ingredients is so crucial (and avoiding any endocrine disrupters)...and this is why I really decided to try this brand...and didn't break the bank doing so!

Good, well priced product I was looking for a product with Vit C. This has it and is well priced and feels nice/not oily on my skin. Not sure about long term improvements yet. April 21, 2015
