Trichoroacetic acid is used in different strengths depending on the individual’s skin and desired results. This helps to correct photodamaged skin and hyperpigmentation. The TCA peel also improves fine lines, texture, and acne scars. Prepping the skin for this particular chemical peel is recommended. Patients report that it feels like a sunburn immediately after the procedure and usually the peeling begins by the 2nd-3rd day and then continues for 7-10 days.
