Litmus Test

I am in the skic care/beauty industry so I have tried a lot of products & I have to say this is amazing! It even makes your makeup look flawless once you have applied this moisturizer first. Because it is a little steep in price, I use something else at night & save this for daytime so I can wear it under my makeup for that flawless looking finish! I have very sensitive eyes & this does not bother them. This is my first DD product to try & I will definitely be trying some of your other products!

I purchased this moisturizer and it has changed my skin its glowing, its softer, clearer and so radiant. I feel beautiful. I use with ain't misbehavin ance cleanser and acne control serum. I live in Atlanta, so it gets pretty hot here. Wears beautifully with makeup. Absolutely no irritation or reaction. I'm in love♥

My dear friend ordered this product and we decided for the price we should share the contents and decide upon the next step.
We both will be ordering this product in the future. Already, my skin has a different feel. I will report more later after more use.

Started using the Litmus Test moisturizer and within and week or two my skin went from dry flakey oily all in the same day to normal. I won't be without it.

I have tried them ALL... and Litmus Test is thee best! Unfortunately (for me), I've developed a pretty high tolerance to glycolic acid and since it doesn't come in levels or strengths, I have to use a lot more to achieve the same results as most... and with the already steep $50.00 for 1 ounce price tag, it can become quite costly. But it's still my favorite... Believe me, if the price weren't so prohibitive, I would never buy any other brand again!

I've tried them ALL... and Litmus Test is definitely my favorite. Unfortunately (for me), I now have a pretty high tolerance for glycolic acid and since it doesn't come in levels or strengths, I simply have to use much more than the average person to achieve the same results... which can get costly. But I still love it the best!

I've used a prescription strength AHA product (30%) for 20+years and LOVED it.. Then when I hit 50 it just didn't work like it had. I bounced around but never again found anything I was CRAZY about. I started using Derma Dr PiL, Photo therapy sunscreen and Photo therapy eye cream...love them all BUT I'd had some MATRIX treatments for Actinic keratosis and afterwards my face had a fine peel constantly. Makeup just emphasised the flaky ness . THEN Litmus Test.AMAZING! I'm 62 and am constantly told how fresh and beautiful my skin is. Sure, I have a few tiny wrinkles too but the pores are fine, tone is even , and so soft I can't tell you. Still use everything else too but I will always buy this...always...

nice and light. seems to collect moisture so skin feels great without feeling greasy. Will need to use longer than the 1 week I've had it but so far no irritation.

I can't believe the difference in the texture and brightness this has brought to my skin. My pores are much reduced and I am very happy with the results. However, the price can be prohibitive and I am not waseful when it come to using the products.

Wow. Wow. Wow! Throughout the '90s I used AHAs and BHAs faithfully, but as the "latest and greatest" pushed their importance aside, I didn't use them regularly. Over a year ago, when I discovered Dermadoctor, my skin was driving me nuts - melasma, aging, uneven tone, dull...I started using Wrinkle Revenge 3, then 2, plus Poetry In Lotion every night, with Wrinkle Revenge Eye Balm and my skin has never been better...until...I got a sample of Litmus Test. I applied the sample at night, before bed, as an alternate to PiL. When I woke up and passed my mirror, I actually did a double-take. My face was radiant, with no sallowness in my olive skin, and the skin around my eyes wasn't puffy or dark! My skin felt as soft as my three year old daughter's skin. Now, this is my every other day alternate with PiL, or I use it beneath my sunscreen if I'm not spending much time outdoors. Fantastic, sublime...not to be missed!
