Single Function 980nm Diode Laser: Dedicated Vascular Removal for Salons | ZENI

Facial Red Blood Vessels & Telangiectasia

Facial telangiectasia presents as visible red or purple capillaries on the nose, cheeks and chin. The 980nm wavelength targets oxyhemoglobin within these vessels, heating the vessel wall until it collapses and is gradually cleared by the body. A clinical study of a new 980nm diode laser reported effective treatment of facial telangiectasias without any observed complications. Multiple sessions may be required depending on vessel size and depth.

Spider Veins & Other Vascular Lesions

The 980nm diode laser is effective for a wide variety of small vascular abnormalities, including spider nevi, cherry angiomas, venous lakes and other superficial vascular formations. The wavelength is particularly effective for linear vessels larger than 350 microns (0.35 mm), making it suitable for both delicate facial vessels and slightly larger lesions on the body.

Leg Veins & Red Blood Streaks

Leg telangiectasia and small varicose veins respond to 980nm laser energy. The wavelength penetrates to the depth of superficial leg veins while being absorbed by hemoglobin. Clinical evidence confirms that the long-pulse 980nm diode laser is effective for leg veins. The platform is suitable for treating vessels up to approximately 1.4 mm in diameter.

Skin Types I–IV

The 980nm diode laser can be safely used on patients with Fitzpatrick skin types I to IV. FDA 510(k) documentation for 980nm vascular laser systems confirms intended use across Fitzpatrick skin types I–V for benign cutaneous vascular lesions, including facial and truncal telangiectasias. The wavelength’s lower melanin absorption compared to shorter visible wavelengths reduces the risk of epidermal damage in darker skin tones.

Selective Photocoagulation

980nm laser energy is strongly absorbed by oxyhemoglobin in red blood cells. When the laser is applied to a vascular lesion, the absorbed energy converts to heat within the vessel. The vessel wall reaches a temperature that causes protein denaturation and vessel wall collapse — a process called photocoagulation. The treated vessel is then gradually absorbed and cleared by the body’s natural processes. Because the energy is selectively absorbed by hemoglobin, surrounding tissue is largely spared.

Porphyrin Absorption Spectrum

The 980nm wavelength is described as the optimum absorption spectrum of porphyrin vascular cells. Vascular cells absorb the high-energy 980nm laser, leading to solidification and eventual clearance of the targeted vessel. This mechanism provides a precise and predictable treatment endpoint.

Collagen Stimulation as a Secondary Benefit

Beyond vessel clearance, 980nm laser energy can stimulate dermal collagen growth during vascular treatment. This increases epidermal thickness and density, so that small blood vessels are no longer exposed, and the skin’s elasticity and resistance are also significantly enhanced. This dual action — vessel removal plus collagen support — contributes to longer-lasting aesthetic improvement. Learn more about laser treatment technology for clinical background.

Output power, pulse width, frequency, fiber diameter, aiming beam, screen size, voltage and certification should be confirmed in the model-specific specification sheet. Industry-typical single-function 980nm vascular laser specifications include 15–30W output power, 15–100ms pulse width, 1–20Hz frequency, 650nm aiming beam and 8–10.4 inch touchscreen.

Is the treatment painful?

Most clients describe the sensation as a brief, warm pinprick or a light snapping sensation. Topical anesthesia may be applied for larger or deeper vessel treatments. No downtime is typically required, though mild redness or swelling at the treatment site may occur and typically subsides within hours to a few days.

How many sessions are needed?

It depends on the vessel size, depth and treatment area. Small facial telangiectasia may respond after 1–2 sessions. Larger leg veins may require 2–4 sessions spaced 4–8 weeks apart. The 980nm wavelength is particularly effective for linear vessels larger than 350 microns, which may respond more predictably than very fine vessels.

How is this different from ZENI’s multi-function 980nm models?

This SKU980NM019-1 is a pure single-function vascular laser with a portrait screen. It contains no nail fungus, physiotherapy, eczema/herpes or lipolysis functions. It is the simplest, most focused 980nm platform in the ZENI line — designed for clinics that want vascular treatment capability without the training and maintenance overhead of multi-modality systems. Multi-function models (SKU980NM014, SKU980NM001-5in1, SKU980NM006) are better suited for clinics that need to address a broader range of conditions.

Can this machine treat leg veins?

Yes. The 980nm wavelength has sufficient penetration depth to target superficial leg veins and telangiectasia. Clinical studies confirm that the long-pulse 980nm diode laser is effective for leg veins, with the platform suitable for vessels up to approximately 1.4 mm in diameter.

What should I request with the quotation?

Ask for the model-specific specification sheet covering output power, pulse width, frequency, spot size, fiber diameter and compatibility, aiming beam, screen size (and portrait orientation confirmation), dimensions, weight and voltage. Confirm the complete accessory list including fibers, handpiece, protective eyewear and power cord. Verify CE or relevant certification documentation for your market.
