Hi,
TCA Cross is a deep chemical peel for acne scars such as deep box-car scars and ice-pick acne scars. Several sessions of TCA Cross might be needed for satisfactory results.
How to Get Good Results from TCA Cross for Acne Scars?
1. Optimise your Recovery
TCA Cross, like Fractional Resurfacing Lasers (Fractional CO2, Erbium, Pico lasers), improve acne scars by "damaging" your scarred skin in a controlled manner to stimulate healing, thereby improving the appearance of the scars.
Your recovery phase is a critical time period. Based on your photos, you are still in the recovery phase. It is important that you apply generous amounts of sunblock and moisturiser during this time to ensure that you get the best healing and minimal side-effects.
2. Combination of Acne Scar Treatments
Your scars appear to need more than TCA Cross.
Deep scars tend to be tethered down by fibrous bands - this requires subcision treatments.
Also, there might be skin atrophy/ localised volume loss which will require filler/rejuran treatments.
TCA Cross is a good treatment but it will not address these aspects of your scars.
It is best to consult your doctor regarding other synergistic acne scar treatments. Scars are best assessed by your doctor face-to-face under different lightings, manual palpation (by feel) and also animation (smiling/talking).
3. Sufficient number of treatment sessions
Collagen production and scar remodelling takes time and multiple treatment sessions - usually 3-5 sessions.
Each TCA Cross/Acne Scar treatment session will progressively improve your scar appearance.
Hope this helps!
Warmest Regards,
Dr Justin Boey
