TCA Cross
TCA CROSS is a precision cosmetic dermatology treatment used to improve selected acne scars and prominent pores by stimulating controlled tissue renewal from within. Trichloroacetic acid is applied directly to the base of the scar or enlarged pore, creating a carefully confined healing response that encourages new collagen formation, shallow tissue regeneration, and gradual remodelling. Over time, this can help soften, lift, and refine the treated area, particularly when used as part of a specialist combination acne scar treatment plan.
Expert Assessment Matters
- TCA is highly effective for treating ice-pick, boxcar acne scars, and deep wide-open pores.
- The application method and concentration of TCA will vary depending on an individual's skin type.
- Recovery time is typically fast, ranging from 3-5 days.
- Combining TCA treatments with fractional lasers can lead to even faster results.

Frequently Asked Questions
TCA CROSS is most commonly used for narrow, deeper acne scars, particularly ice-pick scars and selected small boxcar scars. It can also be used in some cases to refine prominent or enlarged pores where there is a focal, scar-like opening in the skin. The treatment works best when the acid can be placed precisely into the base of the scar, stimulating controlled collagen renewal and gradual remodelling from within.
TCA CROSS is usually less suitable for broad, shallow rolling scars, widespread uneven texture, or scars caused mainly by tethering beneath the skin. In these situations, treatments such as laser resurfacing, subcision, vascular laser, microneedling, or regenerative collagen-stimulating treatments may be more appropriate. At Scars & Lasers, TCA CROSS is often used as part of a tailored combination acne scar plan, depending on scar type, skin quality, pigmentation risk, and overall treatment goals.
