Will TCA CROSS reduce pigmentation caused by acnes?
TCA cross for the use of hyperpigmentation can work. It really depends on how you do the procedure. TCA means trichloroacetic acid. And cross means chemical reconstruction of skin scars. I think if you use TCA or trichloroacetic acid in the classical way for chemical reconstruction of skin scars you will get scarring from that. When you treat hyperpigmentation using such strong strength of the chemical you are putting the skin at risk for scarring. Chemical reconstruction of skin scars typically us a higher percentage concentrations of trichloroacetic acid. This is not the way to treat hyperpigmentation. You're going to want to use way less in terms of the strength of the chemical peels using to help hyperpigmentation. I personally use laser resurfacing. The settings I use with Laser Resurfacing helps with hyperpigmentation. I would not use TCA in this setting TCA is better used for depressed scars and ice pick scars when used in the CROSS method.
Hyperpigmentation from Acne
The best way to treat this hyperpigmentation generally speaking is to use hydroquinones and chemical peels. Please consult an expert in peels. Best, Dr. Green
Superficial Chemical Peels Work Well For Post Inflammatory Hyperpigmenation From Acne; TCA CROSS--Only For Pit Scars
TCA CROSS, either performed with traditional TCA or with full strength phenol is intended for the treatment of ice pick (pit) scars are very enlarged (dilated) pores. It is not intended to treat hyperpigmenation from any cause, since it actually may lead to scarring and persistent hyper or hypo pigmentation when applied over a large area (In TCA CROSS, it is simply placed down narrow shaft of the pit or pore). On the other hand, I have personally been using superficial peels containing full strength glycolic acid, salicylic acid, and Jessner's solution for over three decades in my Upper East Side Manhattan practice. The results for lightening or speeding up the fading of postinflammatory hyperpigmention from many causes, including following acne. can yield quite gratifying, especially if combined with the regular use of at-home, prescription strength agents (such as hydroquinone, or arbutin, kojic acid and glycyrrhizic acid). Be sure to consult with a board certified aethetic physician. Best of luck
TCA cross and ice pick acne scarring
no, TCA cross could make the pigmentation worse. this works well for ice pick scars. Please see an expert. Best, Dr. Emer.
TCA Cross for pigmentation?
This technique was developed in Asia and is used for improving acne scars. It works best for ice pick scars. It can do nothing for pigmentation and in the rare cases, it can actually cause hyperpigmentation.
