Do not attempt to perform high-concentration (30%) TCA (trichloroacetic acid) chemical peels at home, as this presents severe risks of permanent scarring and pigmentation disorders.

Anthony Youn's advice is firmly anchored in standard dermatological practice. Research confirms that high-concentration chemical peels, such as 30% TCA, act by causing coagulation of cutaneous proteins and must be strictly controlled to avoid penetration that is too deep into the dermis (Source: Journal of Clinical and Aesthetic Dermatology, expert review/clinical consensus). The risk of atrophic scarring and dyschromia (hyper- or hypopigmentation) is documented, particularly in darker skin phototypes (Fitzpatrick IV-VI) due to the reactivity of melanocytes, which supports his warning (Source: Journal of the American Academy of Dermatology, systematic review). Application without professional supervision eliminates the ability to adjust contact time or neutralize the acid, exponentially increasing the risk of adverse effects. There is no exaggeration here: the complications mentioned are known and serious side effects of the misuse of professional-grade acids. The approach is preventive and aligned with safety standards in aesthetics.
