Defend derm duo
I just love how the vitamin c goes on. I’ve used it for 5 days and it feels great on my skin. Too soon to notice any changes. Slightly thicker than Skinceuticals but goes on smooth.

I love this skincare line
I started with one product because I was skeptical and was tired of wasting money. I really noticed a difference after two weeks. Then I purchased this duo and my skin looks so much brighter and smoother!

I have been using products from “the other company” for years. I am ecstatic that I am now able to buy quality products at a fraction of the cost and the results have been impressive.
