Why did I break out after vitalize peel?

3 years ago i had mild break outs, andci did a vitalize peel. my skin looked amazing for the first three days after it peeled, but thn i had the worst break out ever with lots of comedones, which were hard to get rid of. I would like to try peels again to get the sale smoothing effects, but im not so sure which one would give le smoother skin without the comedones. any advice? at home i have bn using 20% glycolic pads for years.
