To observe the alteration ultraviolet radiation (UVR) of skin's tolerance after its exposure to the small dose of UVR under the protection of sunscreen.Eleven subjects who applied sunscreen were exposed to 0.75 dose minimal persistent pigment darkening (MPPD) and minimal erythema dose (MED) by the Phototherapy Unit for 4 weeks. Each week their MPPDs and MEDs were measured by solar simulator. Meanwhile, SPECTCOLOMETER® and VISIOSCAN VC98® were used to detect the test areas and control areas.The values of MPPD and MED increased significantly after the exposure to UVR. But there were no visible changes on the surface of skin's texture.With the protection of sunscreen, the UVR tolerance of skin was greatly increased after the skin's exposure to the small dose UV. |
