Why: If you want the strongest chemical peel available, you're probably looking at trichloroacetic acid, a powerful ingredient more commonly known as TCA. Tanzi says TCA is best for patients with extensive scars or damage because of its ability to "retexturize" pores and reduce the look of sun damage.
"The concentrations [of in-office treatments] range depending on the depth of the peel," says Tanzi. A dermatologist may use as little as 15 percent TCA for a light peel or as much as 50 percent for a deep peel that requires several weeks of post-treatment downtime.
TCA is somewhat rare in store-bought treatments because of its inherent strength. "[You'll] see no more than 3 percent in over-the-counter products," says Tanzi.
