TCA CROSS Acne Scar Treatment

Service Description

What is TCA CROSS and who is it for? TCA CROSS — Chemical Reconstruction of Skin Scars — uses precise focal application of trichloroacetic acid directly into individual acne scars to stimulate deep collagen remodeling and progressive scar elevation from within. At New Skin by Lynn, TCA CROSS is offered as a targeted add-on for clients whose acne scars have not responded adequately to microneedling alone. It is particularly effective for ice pick, boxcar, and atrophic acne scars and enlarged pores — scar types that respond poorly to surface treatments due to their depth and narrow structure. How does TCA CROSS work? A precise drop of TCA at concentrations of 35-75% is applied directly into the base of each individual scar using a fine applicator — targeting only scarred tissue while leaving surrounding healthy skin undisturbed. This triggers the skin's natural wound healing response and stimulates new collagen production from the base of the scar upward. Treated scars turn white immediately — a process called frosting — confirming the acid has reached the appropriate depth. What skin concerns does TCA CROSS address? At New Skin by Lynn, TCA CROSS effectively treats: Ice pick scars — deep narrow pitted scars penetrating into the dermis Boxcar scars — wider sharply defined depressions with steep vertical edges Enlarged pores — particularly on the nose, cheeks, and upper lip Deep acne scarring resistant to microneedling or chemical peels alone What results can clients expect? Small scabs form at treated sites following each session — resolving naturally within 5-7 days. Most clients require 3-6 sessions spaced 4-6 weeks apart with visible improvement developing progressively as new collagen forms. Clients with Fitzpatrick Skin Types 4-6 may face elevated risk of post-inflammatory hyperpigmentation and will receive specific guidance from Lynn. Sun protection is essential throughout the treatment series. All treatments are performed under physician medical direction as required by California law. Lynn's Pro-Tip: "TCA CROSS reaches scar depths that surface treatments cannot access — it is the treatment I recommend when clients are frustrated that microneedling alone is not delivering the scar improvement they want."
