50 Percent TCA Peel for Legs?

TCA is considered a medium depth peel. However,a full depth could be reached if a high concentration is used or layering of the peel is done. I would highly recommend that you use the TCA under the direction of physician. I'm very surprised that you could purchase a highly concentrated TCA without a physician. To be specific for the concentration on the legs,i would start with 15% first and go deeper as needed.

I agree with the other responses to your question. The safest way to administer chemical peels is under the direction of a physician. The likelihood of producing scars on the legs with 50% TCA is extremely high. It is simply irresponsible for vendors to sell 100% TCA to individual consumers. I'm glad you asked your question in this forum as you have likely saved yourself a great deal of heartache.
Good luck.

I type this answer with my mouth open. I cannot believe people would sell such a caustic substance online. Experienced dermatologists and plastic surgeons know 50-100% TCA is inappropriate for off-face use because of a variety of medical reasons too complex to discuss here. We prefer 35% TCA for the face and that area is the safest area to peel. Needless to say, suggesting 50% TCA on the legs is irresponsible advice.
I recommend you throw this TCA away. The last person I saw who had a "do it yourself " online TCA peel had to spend several hundred dollars and 2 weeks inside before the scars were corrected.
