Can a TCA Chemical Peel Treat Post Inflammatory Hyperpigmentation (PIH)?

Yes, a TCA peel will improve post inflammatory hyperpigmentation in combination with a sound topical skin care regimen.

 

I also recommend a Melapeel for my patients to improve PIH. 

TCA chemical peels really help with post inflammatory hyperpigmentation such as acne marks. If your skin is more asian or black then a few light TCA peels 10-15% every 2-3 weeks do good. I like to use a bleaching cream with it as well such as Tri-Luma to help prevent any unexpected pigmentation problems and of course a sunscreen as well.
The TCA peels run about $250 each for the face. You can also do spot treatments instead of the whole face which are less expensive.

Brown skin, Asian skin, East Indian and African American skin is prone to hyperpigmentation.
Before you spend $$ on peels or IPL, try these topicals.
This is called post-inflammatory hyperpigmentation (PIH). 
I recommend Melarase AM and Melarase PM creams from Kare Skin as well as a broad spectrum sunblock like Spectrase. Bothe are from Kare Skin. Scler-x post inflammatory hyperigmentation relief complex is a great supplement to take as well. See link below. 
Spectrase is a wide spectrum sunblock SPF 50+that is also recommended to prevent ongoing inflammation. 

The tried and true TCA-Jessner's peel is an excellent strategy to combat post-inflammatory hyperpigmentation (PIH). It absolutely must be done in concert with a topical regimen including Hydroquinone and Retin-A. Typically, a series of lighter concentration peels (10-15%) are employed in series to treat PIH. A commitment to meticulous sun protection is required throughout this regimen for both success and safety. 

PIH can be teated with chemical peels including vitamin A peels, lactic acid, AHA Glycolic and also TCA peels. I would recommend TCA at 8-9% strength, every 2 weeks, for 4 sessions. PLUS fading agents such as Lytera or Hydroquinone. RegardsDr Davin Lim Laser DermatologistBrisbane and Gold Coast
