Glycolic vs. TCA peels
For safety reasons, I would try 2-3 glycolic peels spaced 1 month apart and take note of the results. These are more superficial, and generally very safe. If the results are insufficient, then I would consider TCA peels. That said, you may want to speak to your dermatologist about a modified Kligman's formula cream which can be very beneficial and more affordable. Also, you must wear sunscreen during and after treatment.
