Compare more than advertised treatment speed. Regular use also depends on the light-window area, automatic flashing, access to small areas, cooling level, weight, included heads and clarity of the mode for the chosen body area.
IPL targets melanin and therefore works best where skin and hair have a clear contrast. Very light blonde, grey, white or red hair may respond poorly, while deeper skin tones require especially careful use of the manual's suitability chart.
At-home IPL requires a course and maintenance sessions rather than a single use. Results vary with individual hair growth, skin tone, hair colour, consistency, selected intensity and technique; an advertised percentage is not a guarantee for every user.
Ulike may suit an adult with a compatible skin-and-hair combination who can follow the manual and schedule. Anyone with a skin condition, photosensitivity, sensitivity-increasing medication or other uncertainty should discuss IPL with a clinician first.
