Problems solved by technology

However, this optical design requires relatively expensive optical components, such as diffractive lens arrays or a large number of fiber bundles, making it unattractive for low-cost home-use skin treatment devices
[0007] In addition, the width of the smallest lesion may be relatively large due to fiber spacing in the fiber tract

Embodiment Construction

[0058] figure 1 An exemplary cross-sectional view of a skin treatment device 10 according to an embodiment of the present invention is shown. The skin treatment device 10 is configured and arranged for topical treatment of human skin 100, although in some variations non-human skin may also be treated. For ease of use, skin treatment device 10 may be a single entity. It is generally believed that human skin 100 includes three parts, upper stratum corneum 101 , epidermis 102 and dermis 103 . In the illustrated embodiment, the laser beam 20 is directed (eg, focused) onto the dermis 103, and a treatment zone 50 is shown, although any portion or combination of skin 100 may be treated in accordance with the present invention, see Figure 6 . More details on the interaction of human skin with lasers can be found in Markolf H. Niemz, "Laser-Tissue interactions" Springer publications (1996), which is hereby incorporated by reference in its entirety. An overview of the effect of tem...

Abstract

The invention relates to a skin treatment device (10) for fractional treatment of the skin (100) of a human being. A radiation source (5) emits a multi-mode laser beam (20) with a superposition (23) of mutually different higher-order laser modes. The multi-mode laser beam is configured by said superposition of different laser modes to simultaneously cause a first plurality of high-intensity zones,where the thermal threshold (TC) for collagen denaturation for the treatment zone (50) of the skin is at least reached, and a second plurality of low-intensity zones where the thermal threshold (TF)for fibroblast stimulation for the treatment zone of the skin is at least reached. This is advantageous for obtaining a skin treatment device with a simple and therefore low-cost fractional laser skintreatment system for combined collagen denaturation and fibroblast stimulation. The skin treatment device is based on non-uniform laser radiation in the form of the multi-mode laser beam.

Description

technical field [0001] The present invention relates generally to the treatment of human skin using a skin treatment device. In particular, the invention relates to a device for carrying out such treatments. Background technique [0002] Laser skin rejuvenation is an intervention that uses optical means to deliberately destroy the skin to create new skin tissue. In selective non-ablative photothermolysis based on water absorption, tissue is heated to between 60-100°C to create damaged thermal zones that induce new collagen growth without ablating or vaporizing the skin . [0003] In some at-home devices, so-called topical skin rejuvenation is usually performed by creating distributed small lesions with a typical size of 100-300 μm, surrounded by healthy tissue, minimizing downtime and side effects while maintaining the desired level of efficacy . Thus, a topical treatment is a non-invasive treatment that uses a device to deliver a laser beam that is divided into many, fo...
