This studies was designed to investigate the importance of skin type and UV-exposure on side effects after exposure to an Intense Pulsed Light Home-use device.
21 healthy subjects will receive 8 UV-exposures on one buttock and subsequently three weekly IPL-exposures.
详细描述
Twenty-one healthy subjects will be exposed to UV-exposures 8 times over 3 weeks on a test-area (4 x 6cm) on one buttock to induce pigmentation. This will be followed by 3 weekly IPL (intense pulsed light) exposures. At 24 hours after the first IPL exposure, biopsies will be excised from the buttocks of the subjects (4 each).The skin will be evaluated after IPL exposure for: skin reactions, pain and mRNA expression of two pigment markers.
