A multicentre trial of the epilation efficacy of a new, large spot size, constant spectrum emission IPL device.

This study assesses the efficacy of a new, low fluence, constant spectrum IPL device. In three European centres, 52 females underwent epilation of one arm axilla with the new IPL, the contralateral axilla serving as a treatment control. Satisfied patients at the 1-month assessment received no further treatments and in the other patients up to five further monthly sessions were given. Clinical photography was taken at the pretreatment baseline and at approximately 1 month later. Side effects and hair attributes were graded. Patient satisfaction was graded. All patients completed the study: 11 required one treatment, with eight, 13, 11 and nine requiring two, three, four and five sessions, respectively. Side effects were minimal. A total of 44 patients were very satisfied with the final result, eight were somewhat satisfied and no patient expressed dissatisfaction, giving an overall satisfaction score of 84.6%. In all cases, hair regrowth in the treated side was finer and lighter. The greatest efficacy was seen in coarse dark hair in darker skin, and least efficacy was noted in fine blonde hair in lighter skin. Epilation with this constant spectrum IPL was safe, effective, well tolerated, and with high patient satisfaction. Repeated sessions were required in some patients with lighter hair and skin.
