I did a 35% TCA cross and some scabs fell off 2-3 days later, now holes are much bigger, what can I do?

I recommend following up with a cosmetic dermatologist for after care. I recommend silicone gel with growth factors and hyperbaric oxygen to promote healing. I don't recommend applying chemical peels yourself. They should be applied by a professional. See an expert. Best, Dr. Emer

TCA cross is not a great treatment for pitted scars in oily skin with pitted scars and if done wrong can cause much worse scarring that is difficult to fix.  Skilled laser resurfacing and or excision of the scars while on Isotretinoin (Accutane to reduce the oil) is the best treatment option in my hands. 

See a wound care specialist, TCA peels at high concentrations can be dangerous. For now, its minimising scarring, and promoting wound care. All the best, Dr Davin Lim. Brisbane Dermatologist. Australia.
