Description
TCA Cross (Trichloroacetic Acid Chemical Reconstruction of Skin Scars) is a dermatological procedure for treating acne and atrophic scars. It involves applying high-concentration trichloroacetic acid in a precise, targeted way to individual scars.
Best suited for
- Ice-pick scars
- Deep atrophic acne scars
- Enlarged or dilated pores
Pre-care
- Avoid active skincare (Vitamin A/Retinol, Vitamin C, AHAs, BHAs, Benzoyl Peroxide, strong exfoliants) for 5–7 days before treatment.
- Stop using prescription acne or skin medications (unless directed by your doctor/clinician) at least 1–2 weeks prior.
- Do not undergo waxing, laser, peels, or dermal needling in the treatment area for at least 2 weeks before.
- Avoid excessive sun exposure or tanning (including fake tan) for 2 weeks before treatment.
- If prone to cold sores, commence antiviral medication as prescribed to prevent flare-ups.
- Arrive with clean skin – no makeup, SPF, or skincare products on the area.
Post-care
- Redness, frosting, scabbing or crusting in treated spots is expected – allow scabs to fall off naturally (do not pick).
- Keep the area clean and dry for the first 24 hours.
- From Day 2, cleanse gently with a mild, fragrance-free cleanser and apply the prescribed healing ointment/soothing barrier cream.
- Strictly no active skincare (Vitamin A, C, AHAs, BHAs, scrubs, or peels) until healing is complete (approx. 7–10 days).
- Avoid sun exposure during the healing period and apply SPF 50+ daily once crusting has shed to prevent post-inflammatory hyperpigmentation (PIH).
- No swimming, spas, saunas, or heavy sweating until the skin has healed.
- Some temporary redness or pigmentation may persist as the skin remodels; collagen stimulation and scar improvement continue for weeks to months after treatment.
- Multiple sessions may be required for best results.
