摘要： A wrinkle tissue preparation method is for preparing wrinkle tissue for a light-based wrinkle tissue treatment method. The preparation involves increasing the amount of target particles in the wrinkle tissue. In an overall wrinkle treatment method, these target particles are then ablated by a subsequent light-based wrinkle tissue treatment method. The preparation stage improves the effectiveness of the light-based treatment for performing wrinkle reduction.

摘要： A light-based skin treatment device is for treating skin by laser induced optical breakdown of hair or skin tissue. A focusing system has an exit focusing lens for focusing the incident light beam into a focal spot in the hair or skin tissue. This lens has a central aperture. This serves to reduce back-reflectance from the lens surface, which can cause damage to the focusing system.
