Thulium Laser beauty Machine 1927nm Laser Skin Care Medical Equipment 1. Theory The thulium laser is an infrared laser and the main target tissue for skin absorption is water. Since the water content of the dermis is higher than that of the epidermis, the accumulation of heat and temperature rise in the dermis is higher than that in the epidermis during thulium laser treatment. Since the water content of epidermis is smaller, it will not be damaged by intense heating and cause edema and injury in the heating process. The skin will only be slightly reddened, with a certain sense of heat and pain, but it will not sting, burn or even be damaged. The 1927nm fractional mode is characterized by the use of a fractional handle to focus the laser onto a small spot (approximately 0.1-0.15mm in diameter) to irradiate the skin, achieving a non-ablative or micro-ablative effect, mainly for skin rejuvenation and wrinkle reduction. If the laser is applied for a long enough time, a micro-ablative effect is produced. If the duration of action and energy density are reduced, a thermal coagulation vertical band may be produced, which activates collagen and shrinks the skin. After the treatment, the skin experiences a series of lasting effects. First, the moisture in the epidermis heats up, causing some proteins to micro-coagulate. This simultaneously causes melanin to be damaged by the heat and then gradually discharged from the surface of the body, where it is phagocytosed and metabolized by the body's macrophages. Second, because it penetrates deep into the dermis and slightly stimulates the dermal papillary layer, it not only accelerates collagen synthesis, but also stimulates division. The 1927nm laser, which primarily uses thermal coagulation instead of stripping and vaporization, is a safer infrared laser.2. Application (1) Improve skin texture: reduce fine lines, wrinkles and enlarged pores for smoother and more refined skin. Treatment of static wrinkles: the core principle is to stimulate the proliferation of collagen fibers in the dermis, restructuring the fiber structure and flattening the sunken wrinkles, thus achieving the purpose of wrinkle removal. Treatment of enlarged pores: Through the action of non-peeling fractional thulium laser, skin renewal and metabolism can be stimulated, slight peeling and sebaceous gland secretion can be suppressed. Therefore, after adhering to regular treatment, pores and sebaceous gland secretion will be contracted and suppressed to a certain extent, and the skin will become more and more delicate and smooth. (2) Improve uneven Skin Tone: Reduce pigmentation, sunspots and melasma, make skin tone more even and brighter. The principle of thulium laser treatment in treating dominant vascular melasma is to protect the dermis and avoid irritation. Thulium laser penetrates deeply enough to protect the dermis and reduce the inflammatory reaction, thus reducing hyperpigmentation. (3) Treats acne scars: anti-inflammatory, promotes skin regeneration and improves the appearance of acne scars. The core principle of thulium laser treatment for skin inflammation is that the high temperature of the laser kills some disease-causing bacteria in the skin, and at the same time promotes blood circulation, improves skin metabolism, and achieves sterilization and anti-inflammatory effects. (4) Firming and lifting skin: anti-aging, stimulates collagen regeneration for firmer, more elastic skin. Parameters
