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.
Overview & characteristics
CROSS TCA (Chemical Reconstruction of Skin Scars) is known as a chemical peeling technique in which high-concentration trichloroacetic acid (TCA) is precisely applied in small amounts directly onto the scar tissue. It is described as concentrating its action on narrow, deep areas to stimulate a localized regenerative response, gradually raising the base of the scar over time. It is most commonly discussed in the context of managing narrow, deep icepick-type acne scars.
How to manage
Rather than achieving results in a single session, a gradual, step-by-step approach across multiple sessions is generally recommended to progressively improve the scar base. Crusting forms at the application site and eventually falls away naturally, making sun protection and moisturization important throughout the process. As this clinic care involves the precise application of a high-concentration agent, it should only be carried out under the supervision of a dermatologist and is strongly recommended to be discussed in advance.
Good to know alongside
It is often discussed alongside other scar care options such as fractional laser, subcision, and microneedling. For broader scars, combining it with laser-based care may also be considered.
Everyday care tips
It is best to leave the care area alone without touching or picking at the crusting, allowing it to fall off naturally. Since scar management is a gradual process that takes time, it is recommended to proceed in close consultation with a dermatologist.
