hi everyone, i would like to know more about tca cross 70% treatment....

i've recently undergo tca cross 70% under an aesthetic clinic.

this is my fourth day but I still haven't seen any black crust form over my targeted area yet. 

can i know is it mean the treatment is ineffective? or my acne scar can still heal even there is no sign of crusting and scabbing? Thanks alot

It's hard to say since everyone heals differently. As for me, my skin is raw for the first 2 days and then incrementally darken over the next 3 days before showing any crust. However, not all scars will scab, especially tiny icepick scars.
