What is the highest percentage of TCA used by doctor's your face?

I find that lasers work better , but jessners + TCA 20-35% work very well but can have signficant downtime.  Pheol peels are the most aggressive.  Best, Dr. Emer.

For a solid medium depth peel , most physicians would use a 30 or 35% peel on the face and drop to lower concentrations on the neck and upper chest.  A light peel which is one that you would repeat more often for less of an effect and less downtime would be 15-20%

There are different concentrations/ percentages of TCA (trichloroacetic acid) peels, and generally the higher the percentage, the stronger the peel.  I use 15% and 30% TCA peels, and apply 1-3 layers, depending on the areas treated.  While most patients tolerate the 15% peel with minimal discomfort, the 30% peel is fairly intense; I find that patient (and my) comfort is greatest when using sedation with this peel.  Seek out a dermatologist, plastic surgeon, or facial plastic surgeon who performs skin resurfacing regularly, and schedule a consultation with him/ her to discuss your concerns and come up with a treatment plan.  Best of luck.

Jessner's and 35% is my maximal concentration, however over the years I have largely replaced TCA with Fractional and Fully Ablative laser resurfacing. TCA CROSS is another procedure where by we place very high strength TCA into FOCAL areas of acne scars (eg. Ice pick scars). Only in this setting do I use a higher concentration. All the bestDr Davin Lim Laser DermatologistBrisbane, Australia
