Laser machine 1927nm Thulium laser

Overview
The 1927 nm Thulium fractional laser is a dermatology device designed for superficial skin indications such as pigmentation, sun damage and tone irregularities. Operating at 1927 nanometers, the wavelength is strongly absorbed in the epidermal water content and melanin, enabling targeted treatment of superficial lesions while preserving surrounding tissue.

Introduction
Typically used in fractional mode, the system delivers energy as an array of microzones (dots or columns), creating controlled epidermal ablation and thermal stimulation. The fractional approach promotes faster re-epithelialization and reduced downtime compared with non-fractional ablative lasers.

Key features

• Fractional delivery: patterned microzones to treat targeted areas while sparing adjacent skin.
• Superficial penetration: 1927 nm absorption by water confines effect to superficial epidermal layers.
• Target specificity: effective on melanin-rich lesions such as sunspots and lentigines.
• Collagen stimulation: induces remodeling to improve texture, fine lines and skin firmness.
• Adjustable intensity: settings from mild to high to match patient skin type and clinical indication.
• Minimal downtime: typical side effects limited to transient erythema or mild swelling resolving within days.

Technical specifications

• Wavelength: 1927 nm
• Operation mode: Fractional delivery (microzones / columnar pattern)
• Typical penetration depth: approximately 200–300 µm (superficial epidermal layers)
• Primary targets: melanin (pigmented lesions), superficial water absorption in skin
• Indications: pigmentation, sun damage, uneven skin tone, texture improvement, reduction of fine lines
• Clinical effect: stimulates collagen remodeling and epidermal renewal
• Treatment intensity: adjustable (mild to high) to accommodate various skin types/conditions
• Downtime: minimal; temporary redness or swelling expected to subside within days
