Most patients find a BBL HEROic treatment to be well-tolerated. It is often described as feeling like a quick snap on the skin, with the sensation fading quickly as the handheld device pulses over the area. BBL HEROic’s CoolComfort technology cools the epidermis during the procedure, eliminating the need for topical anesthesia. After the treatment, it is normal for the skin to feel warm for about 30 to 60 minutes.
