Abstract: The invention relates to a lower eyelid treatment device (1), which comprises a skin treatment structure (3) having a protruding shape which is able to perform a periodical first movement through a stationary reference point (P) in a skin treatment zone (8) of the device. Said periodical first movement occurs in the reference point (P) at a frequency within a frequency range between 0.5 Hz and 3.0 Hz. Said periodical first movement is a local movement of the protruding shape through the reference point (P), at a velocity in the reference point (P) within a velocity range between 0.005 m/sec and 0.05 m/sec, in a single local movement direction (12) in the reference point (P) being transverse to a local protrusion direction of the protruding shape. In this manner, the device provides a specific massage of eye bags of a treated person. The massage results in lymphatic drainage of fluid, which undesirably has built up in the skin of the lower eyelid area (52), towards (14) lymph nodes near the ear.

Abstract: The invention relates generally to the treatment of skin using laser light, and more particularly to a non-invasive device and method for such treatment. During skin treatments, heating of the epidermis is undesired because it may cause discomfort for the person being treated, adverse skin reactions and unwanted changes in skin pigment. The invention provides a laser treatment beam having a first 22a and a second 22b beam region of non-zero light intensity disposed at a periphery of a transverse cross-section of the beam, and a third beam region 22c, arranged between the first 22a and the second 22b beam region, of lower light intensity than said non-zero light intensity. The treatment beam 22 exits the device 10 along its optical treatment axis 13.

Abstract: The invention provides a non-invasive skin treatment device (200) comprising: a light source (10) constructed for emitting treatment light, an optical system (20) constructed for focusing the treatment light to a focus position (340) inside the skin tissue, and a positioning member (50) having a skin contact surface (52), the positioning member (50) and the optical system (20) being displaceable relative to each other for adapting a distance between the skin contact surface (52) and a final lens element (30) of the optical system. The final lens element, in use, faces a skin surface (300), and the positioning member (50) and the optical system are displaceable relative to each other into a treatment position (Pt) of the optical system (20) and into a further position (Pf1) of the optical system (20) different from the treatment position.

Abstract: The invention provides a non-invasive r.f. current treatment device to be used with an agent or treatment substance (20), such as an ionic salt solution. The substance is transported using an electric field generated by the device, such as in iontophoresis, to move the treatment substance (20) into the skin so that the skin's electrical transmission of the r.f-current is increased. The path of any r.f. current is influenced by the distribution of the treatment substance (20) in the skin. Applying r.f. current causes heating in skin tissues coinciding with the path of the r.f. current, allowing skin tissue to be treated that is either coincident with the r.f. current path or immediately adjacent thereto. The region of skin treated with r.f. current may be the upper tissue layers. This renders superfluous the conventional hydration step necessary for r.f. skin preparation, which is poorly controllable and highly variable depending on the anatomic site and the individual being treated.
