Brand Overview

This is a good, though fairly basic, fragrance-free AHA lotion exfoliant suitable for normal to dry or combination skin. It contains a mix of the AHA glycolic acid plus urea, an ingredient that can exfoliate when present in high concentrations, while also boosting skin's moisture content.

In terms of how much AHA this contains, we suspect it's 8–10%. The company wouldn't confirm that, but at least the pH of 3.5 ensures the AHA will function as an exfoliant.

Although this product can be an effective exfoliant, it's overpriced for what you get. Beyond the AHA, urea, and some green tea extract, you're just not getting your money's worth. This will moisturize skin, but its formula isn't as state-of-the-art as lots of other facial moisturizers, so using this rather than one of those isn't a great trade-off for your skin.

This deserves its rating because it works (and is an acceptable option for sensitive skin), but you can find superior, less expensive options on our list of Best AHA Exfoliants.

  • Fragrance-free and suitable for sensitive skin.
  • Contains enough glycolic acid and at the correct pH for it to work as an exfoliant.
  • Urea boosts exfoliation while also moisturizing dry skin.
  • Green tea provides an antioxidant kick.
  • Expensive, considering the formula isn't as state-of-the-art as lots of others.
  • Not a brilliant 2-in-1 replacement for your facial moisturizer.

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.
