I've been using DERMAdoctor Litmus Test pH correcting & renewing glycolic acid facial moisturizer since the beginning of March. I originally received a sample from Ulta and really enjoyed it. I decided to purchase a full size, but Ulta was out of the product for weeks. I finally went ahead and ordered it from Beauty.com. (Sephora carries DERMAdoctor products, but not the Litmus Test line).
DERMAdoctor Litmust Test is an entire line of products. It includes a cleanser, toner and moisturizer. I've only used the moisturizer. In regards to the moisturizer, the DERMAdoctor website says:
Litmus Test reestablishes healthy skin chemistry, promotes cellular turnover, soothes and quenches parched, sensitive skin. Restoring proper equilibrium reveals a luminous complexion, the universal indicator of youthful, balanced skin.
Litmus Test is a comprehensive approach to the challenges wrought by hormonal fluctuations, environmental stressors and aging skin physiology:

DermaDoctor Litmus Test makes a lot of promises. And it delivers on them. I am incredibly impressed with this product. I do think that my skin has dramatically improved since I started using it. My hyper-pigmentation is improving. Some acne issues I was experiencing are resolving. And overall, my skin feels considerably more hydrated and just looks better.
I use this product at night. The directions clearly say to use it morning and night, but since some of the ingredients can cause sun sensitivity, I don't use it in the morning. This product does contain a significant amount of glycolic acid so if you have any scratches or really inflamed blemishes or anything like that, it will sting.
It is pricey at $52 for 1oz of product, but a little does go a long way. I've been using mine every day for at least six weeks and I haven't run out yet.
The only truly disappointing aspect to this product for me is the ingredient list. It contains parabens. I realize that a lot of products out there contain parabens, but considering this line is built on the fact that it was created by a dermatologist it's just ... disappointing.
