I have been going to this clinic for 3 months now (3rd full leg treatment, 1st arm treatment)... and the tech was nice enough to offer to do my underarms. She has years of experience and I have never had this happen on my legs so far (and I am loving the results down there!) but today, she ended up burning my left underarm and told me to apply a triple AB cream and to sterily pop blisters. I have read against this on here and need advice! Presently unable to consult/afford dermatologist. Thanks!
