摘要： The invention provides a skin treatment device comprising a laser source (40) and focusing optics (50), such that a focal spot (18) is positioned in a dermis layer (24) of the skin to be treated. The laser beam (42) is powered and focused (16) such that a LIOB (laser induced optical breakdown) phenomenon is obtained, which affects the skin in order to stimulate re-growth of tissue. This in turn reduces wrinkles (30). The device may comprise wrinkle-determining means (52, 54, 56, 58). The focusing optics (50) may have a numerical aperture of at least 0.4. The invention also provides a corresponding method to treat skin, in particular to reduce wrinkles (30), by providing a focused laser beam (16) that causes LIOB in the dermis layer (24) of the skin. The advantage is that damage to overlaying epidermis layers may be avoided by the use of the very local LIOB phenomenon.

摘要： The invention relates to a device (1) for hair-growth control of hairs (3), in particular hairs growing from human skin (5). The device (1) has a laser source (7) for generating a laser beam (9) during a pulse time, an optical system (15) for focusing the laser beam into a focal spot (25), and a laser beam manipulator (17) for positioning the focal spot in a target position. According to the invention, a dimension of the focal spot (25) and a power of the generated laser beam (9) are such that, in the focal spot (25), the laser beam has a power density which is above a characteristic threshold value for hair-growth related skin tissue above which, for the pulse time, a laser induced optical breakdown (LIOB) phenomenon occurs in the hair-growth related skin tissue. The LIOB phenomenon results in a number of mechanical effects, such as cavitation and the generation of shock waves, which damage the hair-growth related skin tissue in positions surrounding the LIOB phenomenon. An advantage of the device (1) according to the invention is that the amount of total energy which is necessary to cause trauma and induce (semi-)permanent cessation of hair-growth is at such a level that irritation and damage of the surrounding skin tissue is very limited or even completely prevented.
