What to know about a trichloroacetic acid TCA peel

TCA reacts with proteins in the treated skin. The practitioner controls the contact and depth to create the intended response, which may range from surface renewal to a more substantial peel. Redness, tightness, flaking, swelling or crusting can occur as the skin heals. The treatment may be considered for texture, selected marks or uneven tone, but the same approach is not suitable for every area or every skin condition. Recent tanning, active inflammation and some medicines can change the plan.

Before treatment, mention cold sores, eczema, allergies, medicines, recent sun exposure and any history of raised scars or pigment changes. Follow the clinician’s instructions about pausing irritating skincare. Afterward, cleanse gently, moisturise as directed and protect the area from sun. Let flakes or crusts detach naturally; scrubbing, picking and early use of acids or retinoids can irritate healing skin. Keep the clinic’s contact details available during recovery.

Call the treating clinic if discomfort, redness or swelling is getting worse, or if you notice increasing warmth, pus, fever, spreading redness, persistent burning or unusual colour change. Urgent care is appropriate for facial or throat swelling, difficulty breathing, faintness or widespread hives. If the product gets into an eye, obtain prompt medical advice and follow emergency instructions.

Ask what depth is planned, what result is realistic for your concern, how your skin tone affects the risk of colour change, which products to stop, how long to use gentle care and when normal skincare can resume.
