TCA CROSS post-care: looking after treated skin

After treatment, each scar opening may sting, redden, swell slightly, or form a small crust. These changes reflect a deliberate local injury and do not need to be rubbed away. The surrounding skin may look normal while the treated points heal at a different pace.

A crust is a temporary covering over fragile new skin. Pulling it off can restart bleeding, increase irritation, and make colour change more noticeable. Texture improvement also continues after the visible surface has settled, so early appearance is not the final assessment.

Cleanse gently with the product and method supplied by the clinic, pat dry, and apply the recommended ointment without rubbing. Keep hands away from the spots, avoid deliberate sun exposure, and use the advised sunscreen once the clinician says it is suitable for the healing surface.

Pause exfoliating acids, retinoids, scrubs, facial waxing, and harsh antiseptics until you receive clearance. Avoid swimming, steam rooms, and strenuous heat exposure for the period your clinic specifies. Do not cover the sites with makeup until the surface is closed unless your clinician has approved a product.

Call the treating clinic if discomfort is becoming stronger, redness is spreading, swelling is pronounced, or the area feels increasingly hot. Drainage, pus, fever, blisters, or a wound that is not closing needs assessment. Eye pain or vision change after treatment near the eyes requires prompt medical advice.

Ask when to wash, which ointment to use, how to handle an accidentally removed crust, and when exercise, swimming, shaving, and makeup are acceptable. Request a contact route for after-hours concerns and a review date for judging scar texture.
