Laser hair removal at WOOA Dermatology targets the melanin in hair follicles to slow regrowth, so you can enjoy smooth skin without constant shaving or waxing. WOOA uses the Clarity laser, a multi-platform device with 755nm and 1064nm wavelengths. The 755nm wavelength is absorbed quickly by dark hair, allowing follicles to be treated selectively while the surrounding skin is protected. An intelligent cooling system chills the skin before each pulse, so larger areas can be treated faster and more comfortably without anaesthesia. Energy, pulse duration and depth are set to your skin tone, hair thickness and follicle depth. Popular areas include the hairline, around the mouth, underarms, arms, hands and feet, thighs and calves. Most patients need 4 to 6 sessions to work with the hair growth cycle. Mild redness usually settles quickly, so daily life can continue straight away.
