What is CROSS TCA?
A chemical peel technique applying high-concentration TCA in small spots to regenerate deep scars
Specialized for narrow, deep scars like ice-pick scars. Multiple sessions gradually raise the scar floor.
Main causes & characteristics of CROSS TCA
CROSS TCA is known as a chemical peeling technique in which high-concentration trichloroacetic acid (TCA) is applied precisely and focally to the scar area. It is described as working by concentrating its action on narrow, deep areas to induce a localized regeneration response, gradually elevating the base of the scar. It is frequently discussed in the context of managing ice pick-type scars that are narrow and deep.
Managing CROSS TCA
Rather than being completed in a single session, stepwise management of the scar base over multiple sessions is generally recommended. As crusting forms and naturally sheds at the treated sites, sun protection and moisturizing care are important. Since this procedure involves applying a high-concentration agent with precision, proceeding under the direct consultation and supervision of a dermatologist is strongly recommended.

Often discussed alongside fractional laser, subcision, and microneedling in the context of scar management. For broader scars, combination with laser-based treatments is sometimes considered.
Everyday care tips
It is advisable not to touch or disturb the crusts and to allow them to fall off naturally. As scar management is a gradual process, proceeding in close consultation with a dermatologist is recommended.
