Trichloroacetic Acid (TCA) has long been recognized as a powerful and effective exfoliating agent in aesthetic medicine. Its mechanism of action is well-documented: provoking controlled chemical exfoliation, it induces deep dermal regeneration, leading to visible improvements in skin quality. TCA effectively addresses various aesthetic concerns associated with aging, including fine lines, deeper wrinkles, sunspots, and age-related hyperpigmentation, significantly enhancing patient self-confidence and overall satisfaction.

The clinical versatility of TCA is due to its ability to achieve different peeling depths based on concentration adjustments. Lower concentrations (10-20%) are ideal for superficial conditions such as mild photoaging, uneven texture, and pigmentary irregularities. Medium concentrations (20-35%) effectively target moderate wrinkles, solar lentigines, and superficial scars. High concentrations (35-50%) facilitate deeper penetration into the dermis, addressing pronounced wrinkles, deeper hyperpigmentation, and substantial photodamage. However, traditional TCA peels carry a risk of prolonged recovery, hyperpigmentation, and occasionally, scarring, necessitating meticulous patient selection, careful application, and rigorous post-procedure care.

An innovative solution addressing these limitations is PRX-T33 by WiQo, which incorporates TCA (33%) combined with hydrogen peroxide and kojic acid. This advanced formulation significantly minimizes superficial exfoliation while preserving deep dermal stimulation. The hydrogen peroxide neutralizes the surface exfoliating action of TCA, eliminating the typical “frosting” effect and minimizing associated side effects. Kojic acid further enhances treatment outcomes by addressing pigmentation issues.

PRX-T33 represents a notable evolution, providing significant clinical improvements with minimal downtime and enhanced patient comfort. Its application extends beyond facial rejuvenation, effectively treating the neck, décolleté, and hands, while seamlessly integrating into combination treatments with dermal fillers, neurotoxins, and injectable biorevitalizers. Complementing clinical treatments with specific home-care products further sustains and amplifies results.

In conclusion, innovations like PRX-T33 demonstrate the ongoing evolution of TCA in aesthetic medicine, highlighting a shift toward safer, highly effective, and minimally invasive skin rejuvenation treatments.
