TCA CROSS at home: before and after

TCA CROSS places a concentrated acid into selected depressed acne-scar points rather than spreading a peel over the whole face. Before treatment, a clinician checks whether the scar type, skin condition, active acne, and history of dark marks make the procedure suitable. Afterward, treated points may look white briefly, then become darker, crusted, or tender while the surface repairs. The visible change develops gradually as new collagen forms, and more than one session may be considered.

Do not copy a clinic procedure with an online acid or improvise concentration, tools, or placement. Arrange a skin assessment and disclose eczema, cold sores, medicines, previous pigment changes, and recent exfoliation. After professional treatment, follow the exact cleansing and ointment instructions, leave crusts undisturbed, reduce sun exposure, and use the recommended broad-spectrum sunscreen once your clinician says the skin can tolerate it. Avoid picking, waxing, scrubs, and other acids until healing is complete.

Contact the treating clinic promptly for worsening pain, spreading redness, marked swelling, pus, fever, or a wound that is not settling. Seek urgent medical help for facial swelling affecting breathing or swallowing, eye involvement, or severe blistering. A new dark or pale patch that persists beyond the expected healing period also deserves review.

Ask which scar types you have, why TCA CROSS fits them, how the acid will be controlled, what aftercare products to use, and which changes should trigger a same-day call.
