What is a Thulium Laser?

Thulium laser is an infrared laser, and its primary target tissue for skin absorption is water. Because the dermis has a higher water content than the epidermis, heat accumulation and temperature rise in the dermis during thulium laser treatment are higher than in the epidermis. Due to the lower water content of the epidermis, it is not damaged by the intense heating during the heating process, causing edema and damage. The skin will only experience a slight redness, a slight sensation of heat, and pain, but no stinging, burning, or even damage. The 1927nm fractional laser mode utilizes a fractional handpiece to focus the laser light onto a small spot (approximately 0.1-0.15 mm in diameter) for a non-ablative, micro-ablative effect. It is primarily used for skin rejuvenation and wrinkle removal. If the laser exposure time is long enough, a micro-ablative effect will occur. However, if the exposure time and energy density are reduced, vertical thermal coagulation zones may form, activating collagen and tightening the skin. After treatment, a series of lasting effects occur on the skin. First, the water in the epidermis heats up, causing some proteins to micro-coagulate. This heat damages melanin, which is then gradually excreted from the body's surface and metabolized by macrophages. Furthermore, because it penetrates deeply into the dermis and gently stimulates the papillary dermis, it not only accelerates collagen synthesis but also stimulates its division.
The 1927nm laser primarily uses thermal coagulation instead of ablative and vaporized lasers, making it a safer infrared laser.
Benefits:
1. Improve Skin Texture: Reduces fine lines, wrinkles, and enlarged pores, resulting in smoother, more refined skin. Treatment of Static Wrinkles: Its core principle is to stimulate collagen fiber proliferation in the dermis, restructure the fiber structure, and flatten concave wrinkles, thereby achieving the goal of wrinkle removal. Treatment of Enlarged Pores: The non-ablative fractional thulium laser stimulates skin renewal and metabolism, causing mild peeling and inhibiting sebaceous gland secretion. With regular treatment, pores and sebaceous gland secretion will be somewhat contracted and suppressed, resulting in increasingly refined and smoother skin.
2. Improvement of Uneven Skin Tone: Reduces dark spots, sun spots, and melasma, resulting in a more even and brighter skin tone. When treating dominant vascular melasma, the principle is to protect the dermis and avoid irritation. Thulium lasers penetrate deeply, protecting the dermis and reducing inflammation, thereby reducing hyperpigmentation.
3. Treatment of Acne Scars: Reduces inflammation, promotes skin regeneration, and improves the appearance of acne scars. The core principle is that the high temperature of the laser kills pathogens in the skin, while also promoting blood circulation and improving skin metabolism, achieving antibacterial and anti-inflammatory effects.
4. Skin Firming and Lifting: Anti-aging and stimulates collagen regeneration, making the skin firmer and more elastic.
