What should you know about TCA 20 chemical peel?

At this concentration, careful assessment and application matter. The clinician chooses the area, preparation, contact time, and number of passes according to your skin and goal. It may be discussed for selected texture, acne scarring, or sun-related changes, but a stronger peel is not automatically the right choice.

A frosted or pale appearance during application may be seen, followed by redness, tightness, crusting, and peeling. Pigment can temporarily change as inflammation settles. A history of melasma or post-inflammatory hyperpigmentation should be discussed before proceeding.

Before treatment, disclose active dermatitis, cold sores, open skin, recent tanning, medicines, allergies, and prior reactions to peels. Pause only the products your clinician names. Avoid self-treating with internet instructions because concentration and application errors can injure skin.

Keep the treated area clean and moisturised according to the aftercare plan. Let crusts and flakes fall away without pulling. Avoid steam rooms, hot showers, intense exercise, swimming, fragrance, scrubs, and direct sun until the clinician permits them. Use sunscreen consistently once advised.

Report escalating pain, spreading warmth or redness, pus, fever, severe swelling, or unexpected blistering to the treatment provider. Emergency assessment is appropriate for breathing difficulty, facial swelling, or eye exposure.

Ask whether your concern needs this strength, how your skin tone affects planning, what healing stages to expect, how to prevent pigment changes, and what follow-up is available if the reaction becomes severe.
