Good stuff Review by mkberry85

I've used products from thousands of brands, literally; from over the counter drug store brands, to high end, to medical grade products. I also was a medical esthetician for a long while, and this is one of the best products that I have ever used- personally or professionally.

Just a clarification on HopeAgain review. You do not need to use products from the same line or company for them to be effective. In fact, I never have strictly used one brand and rarely use more than two products from the same line, let alone the same brand. Likewise, when I worked in esthetics, I used products from multiple lines.

Love DermaDoctor!! Review by HopeAgain

Well, first, I have to qualify that the key to all skincare is to use the same brand/product line for your skincare because they're all designed to work together and that delivers the best results. So, when I try a new product line, I try the line - not just one individual thing, so I feel a little weird posting a review for just one product (I guess I'll post this on the other products I'm using too). Anyway, oddly enough I read about DermaDoctor in a Jezabel article about adult onset cystic acne. I was curious and hopped on over to the website. I've tried TONS of other product lines and brands since my once zit-free skin turned into a nightmare of cystic acne at 25 years old (seriously! Not a teenager. Why was this happening?!). 6 years later, I still hadn't found anything that helped THAT much. My doctor put me on a clinical anti-cyst topical gel. It helped, but not that much and turned my skin into a greasy mess. I decided to give this a try. I got the Ain't Misbehavin' cleanser, the Ain't Misbehavin' serum, and the Ain't Misbehavin' face mask. My skin started improving noticeably. I decided to add the Litmus test toner and this Litmus test facial moisturizer and WOW. My skin hasn't looked this good well. . . ever. Even back in my younger days when I didn't get acne, I ALWAYS had stubborn blackheads on my nose that I'd resigned to managing with a combo of attacking them once a week with a blackhead remover and covering them with makeup. They are GONE. I couldn't believe it. After all these years, no blackheads! And, no acne!!! Anyway, I've read some reviews about miraculous overnight results. Skincare doesn't work that way. It usually takes between 6-12 weeks to really start seeing results. I will say that I noticed improvement within the first week, and now 8 weeks later, my face is clear and (dare I use a cliche?) my complexion is luminous. Even my boyfriend commented on how great my skin looks, and he doesn't usually notice things like that. This stuff is not cheap, but at least in my case, it is worth every penny. If you're like me and your skin suddenly decided to revert to its teenage years well into adulthood, I'd say do yourself a favor, and try these products!

i love this product. since I started using this plus the litmus cleanser, my skin has looked incredibly clear. No more oil, no more blemishes. Not sure the products have anything to do with it considering I am using some oral meds but they definitely aren't hurting.

This product is on the pricey side, however it works wonders. I first bought it a few years ago and loved the results. But after my bottle ran out, I tried several other cheaper lotions expecting the same results. Finally, I came to my senses and purchased it again. I'm so glad I did. It's a great product, and will make your skin glow. I think it's helping with those bitty fine lines that are starting to form. I do use the retinol cream every other night and the facial moisturizer every morning and alternate nights. I swear, I can see those lines fading. I will continue to buy this cream.

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!

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.

From a glycolic acid junkie... Review by Anastasia

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!

Litmus Test is the very best of all our products in my opinion, Review by Karen

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...

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.

NOT Your Ordinary Glycolic Cream - This One's Magical! Review by sba, Trabuco Canyon, CA

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!

Too harsh for sensitive skin Review by JWB, Knoxville, TN

Value

The benefits of this product sound wonderful, and many people may be able to tolerate this and reap the rewards. However, I have aging, sensitive skin (50 years old) and am prone to rosacea and redness. My skin begins to sting as soon as I apply the moisturizer, and it still burns throughout the day. Also increases redness. I don't think my skin could tolerate this product even with continued or less frequent use. Sorry Dermadoctor, you have great skincare products and I had high hopes for this one, but it was not for me.

improved acne Review by CN, MA

Being almost 40, I have fine lines and some deep ones. But also suffer from adult acne. Blackheads and whiteheads. It is extremely frustrating. I exfoliate regularly and still have problems. I started using this lotion along with the toner and have found that my acne has greatly improved. I still have large pores on my nose and feel that this will always be problematic and I don't really feel like it did much for my fine lines. I have finished one bottle of lotion and am about to order another. I want to keep trying since I do feel that my skin looks and feels better
