Brand Overview

One of DERMAdoctor’s most popular products is KP Duty, a treatment cream designed to improve a skin disorder known as keratosis pilaris. More commonly known as KP or chicken skin, this disorder is characterized by a swath of pink to red, raised bumps dotting the upper arms and thighs of many people. It’s a benign condition but one many find unsightly. 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. That’s one of the reasons we rated DERMAdoctor’s original KP Duty product highly.

The backstory above was necessary because KP Duty Intensive Priming Serum is meant to be applied before the company’s original KP Duty treatment, with the goal being to further reduce redness and inflammation. To that end, this lightweight serum contains several anti-irritants along with some good skin-repairing ingredients and antioxidants. The tiny amount of glycolic acid isn’t enough to promote exfoliation, but if you’re using another AHA (or BHA, which many find preferable for KP), exfoliant this isn’t an issue.

The major problem we have with this product is the price: Assuming someone with KP will be using it on affected areas, one ounce of this product isn’t going to last long if applied daily to arms and legs. For certain, this isn’t a product that will offer much if any improvement for KP, especially not when compared to many other well-formulated body products that cost a lot less.


  • Lightweight serum texture won’t make keratosis pilaris (KP) worse.
  • Contains a very good range of antioxidants and anti-irritants to help reduce redness.
  • Fragrance-free.


  • Expensive if you plan to apply this daily to larger areas affected by KP.

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.
