Permanent Hair Removal — Laser Epilation

Laser hair removal at Petra Clinic uses selective photothermolysis: laser energy at the appropriate wavelength is absorbed by melanin in the hair follicle, heating the follicle to a temperature that damages its growth cells while leaving surrounding skin unaffected. Results are long-lasting — clinical studies show 60–90% permanent reduction after a full course — with treated hairs shedding over two to three weeks after each session. Because only hairs in the active growth phase (anagen) can be effectively treated, a minimum of five sessions spaced four to eight weeks apart is needed per area. Petra Clinic treats the full body including face, underarms, bikini and intimate areas, legs, arms and back. Preparation requires shaving 12–24 hours before each session and avoiding waxing or plucking for four weeks prior.
