Description

Exfoliating skin handheld device for dermatology

Technical Field

The invention relates to the field of skin science and technology, in particular to a dead skin removing handheld device for dermatology.

Background

The skin is divided into epidermis, dermis and subcutaneous tissue; the surface layer of the skin is divided into five layers, namely a basal layer, a spinous cell layer, a granular layer, a transparent layer and a cuticle from bottom to top in sequence. Skin cells grow from the basal layer and undergo aging and death processes as they go out, and the horny layer is the final product of the continuous regeneration of epidermal cells, the thickness of the horny layer on the surface of the skin is thick, the skin loses luster, becomes dull, peels off, generates wrinkles and the like, and the horny layer is also commonly called dead skin. The cycle of skin keratinization is about one month, so cosmetic experts recommend exfoliating once in 28 days. At present, a plurality of mechanical products for polishing cuticles exist in the market, most of the mechanical products utilize a motor to drive a friction drum to rotate and then act on the cuticles of human bodies so as to achieve the aim of removing the cuticles.

Chinese patent (granted publication No. CN 102958461B) provides a skin removal device comprising a housing having a handle portion, a drum assembly and an electromechanical drive system; a drum assembly connected to the handle portion, the drum assembly including a drum having an abrasive outer surface; an electromechanical drive system is at least partially located within the housing and is configured to rotate the friction drum. This technical scheme is through setting up the rubbing drum, grinds off cutin with the mode of grinding.

Although the cutin is ground off by the grinding mode through arranging the friction drum in the technical scheme, the cutin which is ground into chips is difficult to be splashed everywhere and difficult to be cleaned because the cutin is polished by the friction drum.
