Review Overview

This body moisturizer is designed for those struggling with a skin condition known as keratosis pilaris (KP). This benign condition is characterized by red, raised bumps on skin covering the upper arms, legs, and buttocks. Although there isn’t a cure for KP, gentle cleansing, disinfecting with benzoyl peroxide, and exfoliating with a well-formulated AHA or BHA product can make a remarkable difference in the severity and appearance of these bumps. This product contains the AHA glycolic acid (approximately 10%) to exfoliate skin and its pH is low enough for exfoliation to occur, although salicylic acid (BHA) is preferred for KP because it is oil-soluble and can penetrate into the pore where the problem begins. On the other hand, some people find that their KP responds just as well to exfoliation with AHAs. It is best to experiment to find which option works best for you (Source: http://emedicine.medscape.com/article/1070651-treatment).

That said, KP Duty Moisturizing Therapy for Dry Skin is an excellent AHA body moisturizer for normal to dry skin needing exfoliation (whether KP is present or not). It contains an impressive amount of antioxidant green tea extract and its urea content will help boost skin’s moisture levels and improve barrier function. Those looking for the same level of effectiveness for less money may want to consider Paula’s Choice Skin Revealing Body Lotion with 10% AHA.


KP Duty incorporates medically proven technology including ingredients for hydrated and healthy skin. Medically potent levels of Glycolic Acid blends with Urea, the dermatologist recommended humectant, to soften and smooth away the driest roughest skin.

Brand Overview

DERMAdoctor At-a-Glance

Strengths: Company provides complete product ingredient lists on its Web site; well formulated AHA products; sunscreens provide critical broad-spectrum protection, good oil-control product; a couple of great, though pricey, cleansers.

Weaknesses: Expensive; mostly poor anti-acne products; anti-wrinkle products making imossible claims; clinical studies alluded to are not made available to the public (which is odd, given that this is a brand fronted by a dermatologist); some product formulas suffer due to jar packaging.

The DERMAdoctor line is the brainchild of Kansas City-based dermatologist Dr. Audrey Kunin. Dr. Kunin's Web site retails not only the DERMAdoctor brand but several products from other brands, many of which have ties to specific dermatologic concerns (everything from athlete's foot to warts). Many of these specialty products are available from your local drugstore, but Kunin's site provides helpful, mostly reliable information concerning various skin-care concerns.

We wish her own products followed the strength of her advice, but alas, most do not. This is another dermatologist-developed line with plenty of products whose names and claims make you think they're a cosmetic corrective procedure in a bottle (or, in some cases, a jar, which is never a good packaging move). There are some products to pay attention to, though whether you want to strongly consider them or not comes down to how much you feel comfortable spending (DERMAdoctor products aren't cheap).

DERMAdoctor isn't exactly "your prescription for beautiful skin" but Dr. Kunin gets enough right that her line isn't one to gloss over, particularly if you're shopping for sunscreens, AHA products, and facial cleansers. Those with acne should look elsewhere, because DERMAdoctor's products don't have the solution, despite their cute product names.

For me, there was better and cheaper.

At first, this was a miracle. The KP bumps on my arms did become dramatically reduced. Not totally gone, but better than it was. The lotion is thick and would feel good working into my skin. Your arms are sticky for awhile, but it eventually soaks in. I stopped using this because I found Paula's Body Treatment with BHA. The BHA lotion works better for me and is a LOT cheaper. It soaks in faster, too. I do appreciate the KP Duty lotion and if Paula disappeared, I'd use it again.
