Vertical 1927nm&1550nm Thulium Laser

The 1927 nm & 1550 nm fractional fiber laser is a professional dual-wavelength mid-infrared system offering non-ablative and micro-ablative modes. By combining a wavelength optimized for epidermal resurfacing with one that penetrates deeper into the dermis, it promotes collagen regeneration, stimulates epidermal reconstruction, and delivers significant anti-inflammatory and deep anti-aging effects. It is a preferred solution for skin rejuvenation, acne and acne-scar repair, oil control, and treatment of inflammatory pigmentation and other pigmented lesions.

Clinically, the device is intended for trained professional operation and user-friendly: treatments are less painful, require almost downtime depends on treatment settings and client response, and the system uses no consumables. It can be combined with topical actives or drug-loaded protocols to enhance and prolong results, making it attractive to patients and a sustainable revenue source for medical clinics and beauty salons.

The 1927 nm thulium component (often called the BB Laser) produces controlled photothermal effects and thermal coagulation in water-rich tissue. Its high absorption in water enables both ablative and non-ablative effects with precise depth control determined by pulse energy, delivering dermal remodeling, pore tightening and wrinkle smoothing while reducing the risk of post-inflammatory pigmentation compared with single ablative methods.

How It Works

Thulium lasers operate at a wavelength of 1927 nanometers, penetrating the skin to a depth of approximately 200-400 micrometers. This depth allows the laser to precisely target the epidermis and superficial dermis, effectively treating superficial epidermal problems without causing significant damage to the epidermis. The 1927nm fractional laser is characterized by using a fractional handpiece to focus the laser into a tiny spot (approximately 0.1-0.15mm in diameter) to irradiate the skin, achieving a non-ablative or micro-ablative effect, primarily used for skin rejuvenation and wrinkle reduction. If the laser irradiation time is long enough, a micro-ablative effect can occur. Shortening the irradiation time and reducing the energy density may create thermal coagulation vertical bands, thereby activating collagen and causing skin contraction.

Furthermore, these microchannels can enhance the penetration of growth factors, peptides, and cosmeceutical essences, optimizing post-treatment results.

Treatment Characteristics of Thulium Laser

Thulium laser (Tm:YAG) is an infrared laser. In the wavelength range of 400-2000nm, the laser penetration depth increases with the increase of wavelength. The skin penetration depth of 1927nm thulium laser is the deepest, the scattering effect is strong, and the thermal effect of dermal tissue is significant.

The main target tissue of 1927 thulium laser is water. Since the water content of dermis is higher than that of epidermis, the heat accumulation and temperature rise of dermis are higher than that of epidermis during thulium laser treatment. As a “window”, the epidermis has limited heating, and the heating is mainly reflected in the dermis, accessory organs, and even subcutaneous tissue.

During the penetration process, the hemoglobin in the blood vessels absorbs it more strongly, so it has the effect of coagulation, treatment of red blood streaks and acne (inflammation).

Because thulium laser has a deep penetration depth and has a significant thermal diffusion effect on the skin, it is highly safe and not easy to burn the skin.

Non-ablative treatment of thulium laser does not damage the skin, has no inflammatory reaction, is not easy to stimulate pigment cells and tyrosinase activity, and is not easy to cause pigmentation.

After Thulium laser skin treatment, collagen can be reconstructed, thus achieving the effects of wrinkle removal, anti-aging, lifting, whitening, etc. Its non-invasive and non-inflammatory characteristics can also be used to treat vascular chloasma, acne, etc.

FAQ

▶What is the difference between Thulium laser treatments in aesthetics and medicine?

Thulium losers are mainly used in assthetic reatments with a wovelength of 1927nm,using non-ablative and micro-oblative treatments to improve somefacial skin issues, such as chloasma, acne, scars,etc.

▶What is the difference between Co2 laser 10600nm and Thulium laser 2940nm?

Influenced by traditional CO2 laser design, most commonly used infrared lasers are fractional lasers. There are two transmission methods: fiber optic transmission (1550nm, 1927nm), and optical fiber transmission (2940nm and 10600nm). This is because the longer-wavelength infrared lasers experience excessive losses in optical fiber transmission, necessitating the use of optical fiber transmission arms (at least for now).

Laser"penetration depth"and"treatment depth"can be two different things, often depending on the laser energy density.

During treatment, because 2940nm has the highest water absorption coefficient, when it reaches the epidermis, it is highly absorbed by the water-containing stratum corneum and papillary dermis. High laser energy can immediately cause exfoliation, vaporization, and charring in the epidermis. Therefore, during treatment, we cannot allow 2940nm erbium lasers to penetrate the dermis and form a"thermal coagulation zone."

The 10600nm laser has an absorption coefficient second only to 2940nm, allowing it to penetrate the epidermis. It primarily absorbs water in the dermis, allowing it to penetrate more easily with high-energy irradiation, causing micro-exfoliation and reaching the dermis. However, increasing the energy and exposure time can result in bleeding, charring, burns, and vaporization and exfoliation.

1550nm/1927nm are located in the near-infrared spectral range, which has two small peaks in water absorption. In comparison, water absorbs only one-sixth as much of the 1927 thulium laser as CO2. Therefore, while maintaining safe therapeutic energy, it can potentially penetrate deeper into the skin than CO2, avoiding vaporization and charring reactions. This means it avoids the intense damage to skin tissue that could lead to inflammatory reactions and stimulate melanin activation. Given this premise, the 1927, primarily used for thermal coagulation rather than ablative vaporization, can be considered a safer infrared laser, offering broader application prospects.

▶What is 1927nm Thulium Laser?

The fractional 1927nm thulium laser is a solid-state laser with a wavelength of 1927-1940nm. It is a long-pulse infrared laser, It emits lighting a dot-matrix scanning pattern. The main target chromophore of the thulium laser is water, but the melanin and hemoglobin in the skin also absorb the laser energy. It is one of the important machines in the 3D mesodermal whitening and anti-aging therapy.

Thulium laser has the functions of lifting and firming, treating static wrinkles, whitening and lightening spots (chos sma, pilgmentction), ant-inlammatory,.ollcontrol and acne removal, shrinking pores,shrinking eye bags,iting eyelids,acing dark circles,scolp care to stimulate halir growth, open the skin barier, ancenhance the absorption rate of functional products.

▶How does a thulium laser work?

A thulium laser works by stimulating collagen production and inducing its contraction, thereby shrinking pores, improving fine lines, and firming the skin. During penetration, hemoglobin in blood vessels absorbs it more strongly, thus having a blood-clotting effect and treating rosacea and acne (inflammation). It has an excellent effect on breaking down superficial melanin, making it extremely effective in treating acne scars and dull skin tone!
