TCA Cross is a skin rejuvenation treatment causing Chemical Reconstruction of Skin Scars (Cross) through Trichloroacetic Acid's (TCA) skin repair action, one of the most preferred treatment options for ice-pick acne scars specifically. Dr. Nivedita Dadu at Dadu Medical Centre provides acne scar reduction treatments with safety and precision, helping patients achieve genuinely smoother skin. TCA is typically used in low concentrations to improve facial scars and skin ageing, and TCA Cross for acne scars is the most popularly performed treatment for atrophic scars. Inexpensive, safe, and effective with successive sessions, the procedure deposits a concentrated form of TCA directly onto the site of atrophic scars, causing a controlled inflammatory reaction that boosts new collagen production. As new collagen forms, it fills the depressions caused by scarring, leaving smooth, even-textured skin. Available at Dadu Medical Centre Vasant Vihar (South Delhi) and Rajouri Garden (West Delhi).

The treatment is performed by medical experts and takes just a few minutes, depending on how many scars need treating.
What makes TCA Cross uniquely suited to ice-pick scars is its precision: because the concentrated acid is applied only to the scar itself and not the surrounding tissue, it can trigger a strong, targeted inflammatory response exactly where new collagen is needed, without broadly affecting healthy skin. Collagen stimulation from that controlled inflammatory reaction takes at least 3-4 weeks to begin forming and peaks around 3-4 months, which is why treatment is gradually done across multiple sessions rather than delivering results in one visit. Most candidates need 3 to 6 treatments, repeated at 2 to 8-week intervals over roughly 6 months, for optimum improvement.
TCA Cross stands for Chemical Reconstruction of Skin Scars using Trichloroacetic Acid. A concentrated TCA is applied precisely on the acne scar, not the surrounding skin, to trigger a controlled inflammatory reaction that boosts collagen production, gradually filling in depressed scars for smoother, even-textured skin.
It is one of the most preferred treatments for atrophic (depressed) acne scars, especially ice-pick scars, and also works well for boxcar and rolling scars. It can also treat deep or prominent open pores.
TCA is applied only to the scar with a very fine instrument, so it is well-tolerated. There is a downtime of about 5-6 days: frosting for the first 12 hours, mild redness or soreness that subsides in 24-48 hours, and small scabs that fall naturally in 3-7 days.
Most candidates require 3 to 6 treatments for optimum improvement, usually repeated at 2 to 8-week intervals over about 6 months. Collagen stimulation takes at least 3-4 weeks to begin and peaks at 3-4 months.
Do not pick the scars; let them fall off naturally. Avoid normal makeup and sunscreen until healed, avoid harsh cleansers, apply prescribed moisturizers and antibiotics, and drink plenty of water. Normal face washing and makeup can usually resume after 7-10 days.
TCA Cross is one of the more inexpensive, safe acne scar treatments available. Exact cost depends on the number of sessions needed and scar severity; contact Dadu Medical Centre for personalised pricing.
