Target Depth and Mechanism: The 1927nm laser primarily affects the lower epidermis and upper dermis, where pigmentation and skin problems such as discoloration, wrinkles, and laxity are primarily found. Thulium Laser-1927nm is higher water absorption than Er:Glass (1550nm) about 10 times, less than CO2 laser about 24 times 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. 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. 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. Firming and lifting skin: anti-aging, stimulates collagen regeneration for firmer, more elastic skin.
