Most probiotics that you buy over the shelf are worthless. Never mind the fact that most aren't even living by the time you get it off the shelf at the store; most don't survive the trip from your mouth down into your stomach.
Also beware of probiotics from dairy products, perhaps except yogurt or kefir, they tend to break people out still.
While its true that antibiotics wipe out both good and bad bacteria, a couple rounds of medicine here and there isn't going to make you lose enough healthy strands that you need to supplement with them.
Lastly, even if you do feel you are seeing a benefit from them (accelerating healing, healthier stools etc) once you stop taking them your right back to where you started.
I don't know your whole background with acne, but in my opinion if your still breaking out pretty regularly look into the common diet allergens (dairy, wheat, gluten, soy, corn, nuts) and all facial/hair care products.
I've been clear for a while now, but last year I was breaking out from my shampoo! I didn't realize it for the longest time and all the while I was becoming so anal about my diet that it became a chore to eat! Not worth it in my opinion....
Don't mask the symptom, find the cause and be on your way
Panic, when you say a couple rounds of antibiotics, do you mean months use of antibiotics or few weeks?
Do you think that antibiotics can permanently affect the skins healing ability or no?
yea i agree with your probiotic info, but if its found in fridges, its good
