The Duke Antioxidant patent describes the formulation parameters required for effective delivery of vitamin C to skin: 1) pure l-ascorbic acid (vitamin C); 2) an acidic pH within the 2.0-3.5 pH range and; 3) a concentration between 10%-20%. SkinCeuticals is the only brand to formulate antioxidants according to these parameters.

Reducing collegen cross linking!
I've been using the Serum 20 since the serum 15 was discontinued and have noticed that it is removing more cross linking damage than the Serum 15! I've also been trying it with changing my white hair back to its original color with some small success. Ditto with some veins in my legs! Skin on my legs is much thicker so reaching the veins that began becoming more pronounced about 8 years ago has taken longer but does appear to be working!

I really wanted to be wow'ed by the product especially for the price. However, I did not find that it was so much more amazing then cheaper alternatives. It is great for all skin types and I know many people who have had great results using this product.

Love this serum, usually apply it after my vitamin c serum in the morning and use after AHA/BHA in the night before going to bed and follow it with a moisturizer . Love the way my skin feels next day, very hydrated and plumped.

I purchased this recently with my normal cleanser to compliment my sun protection regimen. It was not greasy and left my skin feeling smooth and soft. It will be my new buddy to sunscreen to prevent damage on daily basis! Only negative is the price point
