TCA CROSS downtime: what to plan for

Downtime is mainly about the appearance and sensitivity of the treated points rather than being confined to bed. The skin may sting soon after treatment, then feel tight or tender. Pinpoint areas can darken and crust as the chemical treatment creates a focused injury within selected scars. The visible marks may be difficult to conceal while they are fresh, and makeup should not be applied until the surface is closed and the clinician permits it.

Your schedule also matters: heat, sweating, friction and dust can irritate healing skin. The amount of visible recovery depends on the number and depth of scars treated, the strength and placement of the application, and how your skin responds.

Arrange gentle cleansing, the recommended aftercare product and reliable sun protection before your appointment. Keep the area away from rubbing, swimming, saunas and strenuous heat exposure until your clinician clears them. Avoid picking at crusts or trying to speed recovery with exfoliation. A calm schedule with fewer social commitments can make the visible phase easier to manage. See the procedure overview for [TCA CROSS](/treatments/aesthetic-procedures/tca-cross/) and the ingredient explanation for [Trichloroacetic Acid](/materials/trichloroacetic-acid/).

Ask the clinic for advice if discomfort is increasing, redness is spreading, swelling is pronounced, or healing areas are draining pus. Fever, a rapidly worsening reaction, or swelling near the eyes needs prompt medical assessment. Breathing difficulty is an emergency.

Ask how long you should avoid exercise, heat, swimming and makeup; whether your work setting affects timing; and what to do if a crust comes off early or the treated skin becomes unusually sore.
