Innovation 1
L-ascorbic acid has a reservoir effect, which means it can’t be washed off or rubbed off for a minimum of 72 hours.
In the morning after cleansing, apply 4-5 drops to a dry face, neck and chest. Can also be used on the backs of the hands.

It is normal for vitamin C products to darken after opening due to air and light exposure. Any change in color does not affect the product's efficacy.

beautiful C+AHA is great for my combination skin - I use it at night and spot treat as needed in the mornings if i have any unruly pop-up blemishes. My hubby even asks for "the special face potion" sometimes! It leaves my skin feeling SO soft looking bright and balanced in the mornings - a great part of my nightly ritual! August 9, 2012
Glowing Skin! I definitely reccommend this product for anyone that has oily or acneic skin. I can say that since I started using this product (about 3 months ago) my skin is softer, smoother and has a healthy glow to it. I get compliments all the time on how great my skin is. I also use the Retinol 1.0 and when I apply the C+AHA the next morning there is some major tingling but it always passes quickly. I love this product and will continue to use it until they stop making it. October 9, 2011
Excellent! I have lived in Texas for more than 30 years... Unfortunately, I have the sun damage to prove it. I also suffered from cystic acne as a teen. This product has done wonders for evening my skin tone and smoothing out the texture of my skin. This product is excellent for daily use. I place 2 drops on top of my hand in the morning and then apply to my face...now hands and face benefit! August 14, 2011
