If a licensee intended to achieve the strongest possible chemical peel, which acid should they select?

Selecting Trichloroacetic Acid (TCA) for the strongest possible chemical peel is appropriate due to its deep exfoliating capabilities. TCA is a medium to deep peel, and it effectively penetrates the epidermis and can reach into the upper layers of the dermis. This depth of penetration allows TCA to significantly improve various skin issues, such as deep wrinkles, hyperpigmentation, and other texture irregularities.

Unlike more superficial peels, which primarily target the outer layer of skin and may lead to milder results, TCA can stimulate collagen and elastin production more profoundly. This makes it particularly beneficial for clients seeking dramatic improvement in skin texture and tone.

In contrast, glycolic acid, typically associated with superficial peels, can enhance the skin's surface but does not offer the same depth of treatment as TCA. Alpha Hydroxy Acid (AHA) encompasses a broader category of acids that generally produce less aggressive results compared to TCA. Salicylic acid, while effective for oily and acne-prone skin due to its ability to penetrate and clear clogged pores, is less effective for achieving the dramatic transformations that TCA can provide.

Therefore, for achieving the strongest possible chemical peel results, TCA is the most suitable
