Reviewed and rejected: DERMAdoctor Picture Porefect

Is a Solution for:
Large Pores
Reviewed by Marta October 3, 2008 1 Comment
Within half an hour of using DERMAdoctor Picture Porefect ($40) on my nose to see if it would, indeed, minimize pores, I looked like I was auditioning for Bewitched. The itchiness that caused my nose to twitch as I tried to resist scratching it had been preceded by two other equally unpleasant sensations: the first was a tightness, as though my skin had shrunk; the second was stinging on one side of my nose.

I often find that DERMAdoctor's formulations are a little heavy-handed and this is no exception. Why stop at one alpha hydroxy acid (exfoliating agent) when you can squeeze in five. There is also retinol, which plays a similar role. No wonder I keep scratching my nose: the two major side effects of alpha hydroxy acids are irritation and sun sensitivity.  The FDA has issued the following guidelines for AHAs in cosmetics:

  • The AHA concentration is 10% or less

  • The final product has a pH of 3.5 or higher

  • The final product must have an effective sunscreen in the formulation or warn people to use sunscreen products


There is no sunscreen in Picture Porefect.

I am curious about the inclusion of aluminum zirconium tetrachlorohydrex glycine. This is an antibacterial used in deodorants. It is banned in Europe. DERMAdoctor's own website admits that aluminum products can cause irritation but goes on to claim that "aluminum zirconium tetrachlorohydrex glycine, is much better tolerated by the skin and less likely to cause irritation or acne". That may well be, but aluminum is still strongly associated with neurotoxicity, which is why Europeans aren't too keen on it.

Polyacrylamide is another eyebrow raiser. It is something you will also find in an injectible filler called Aquamid. One study suggests it can degrade under normal environmental conditions, releasing acrylamide, a known nerve toxin.

    I just want to leave a quick comment in case any other oily-skinned readers happen to come across this entry. I have resistant, not sensitive skin, and this product feels soothing, and it's never itched or burned my skin. I think it's fantastic for improving the appearance of my pores, and reducing oil breakthrough. I use it as a primer beneath sunscreen, or on top of sunscreen, and/or makeup. It helps mattifying the annoying grease from sunscreens, particularly zinc and titanium ones, and it smooths the bumpy, pore-ridden areas. The restrictions for use of Aluminum Zirconium Tetrachlorohydrex Glycine in antiperspirant preparations in Europe is exactly the same as it in the US: it cannot be used in aerosol products. The health concern comes from inhalation of AZG, not topical application.(http://www.cosmeticsdatabase.com/product/129529/Secret_Skin_Renewal_Invisible_Solid_Antiperspirant_&_Deodorant,_Velvet_Powder_Sticks/?prod_id=129529), (http://cosmeticsinfo.org/ingredient_more_details.php?ingredient_id=125)
    The concerns about Polyacrilamide were investigated in 2003, and it was determined that at the regulated concentration for use in cosmetics, it is safe. http://cosmeticsinfo.org/ingredient_details.php?ingredient_id=398
    A very small amount of product, topically applied, is needed for application, once a day.
