Properly done and with high TCA %, yes, its very effective.

what doi expect after the treatment

Huh?

tca cross + fractional co2 is this treatment combination is good to my acne scar ?

Why don't you formulate a proper question before you blab your picture all over the forum?

i think that TCA cross + co2 lasers + recell are the most effective treatments we have today for scars

but will need time: i do think TCA is the most powerful non-cirurgical source that can lift up the atrophic scars and you can do at home, if you can manage to lift up them with TCA cross then 3 session of CO2 with a GOOD and EXPERIENCED surgeon << a good professional is the most important thing
