Intimate Area Skin Rolling Needle

Skin roller needle is a cosmetic device that uses densely arranged micro needles (0.25-2.5mm) on the surface of a roller to physically stimulate the skin. The core principle is the "minimally invasive wound regeneration and repair" mechanism. The process of its action can be divided into three stages: Micro needle puncture: forming controllable microchannels on the surface of the skin, activating the repair response of the epidermis and dermis layer; Collagen induction: By stimulating fibroblasts to secrete collagen and elastic fibers, it improves skin structure and elasticity; Nutrient penetration: Microchannels temporarily enhance the transdermal absorption efficiency of active ingredients such as hyaluronic acid, growth factors, and collagen. The core advantages of skin needle rolling: 1. Promote collagen regeneration: By stimulating the dermis layer with microneedles, the synthesis rate of collagen and elastic fibers is induced to increase by 30% -40%, significantly improving pro…
