The 1927nm thulium laser represents the most advanced domestic technology available, delivering superior micro-ablative performance for epidermal lesions with exceptional beam stability and reliability.
Synchronized Dual-Wavelength Emission
Simultaneous 1927nm + 1550nm emission treats both epidermis and dermis in a single pass—addressing superficial pigmentation while stimulating deep collagen remodeling without extending procedure time.
Three Specialized Treatment Modes
Standard Fractional for precise spot treatment, Sliding Mode for rapid large-area coverage, and Private Mode for specialized gynecological applications—all in one device.
Enhanced Safety for Diverse Skin Types
Non-ablative fractional mechanism preserves epidermal integrity, making this system ideal for Fitzpatrick III–VI patients with significantly reduced PIH risk compared to ablative alternatives.
Overview
The Gentlefrax PRO 1927/1550nm Laser System combines China’s most advanced 20W thulium technology with a powerful 30W erbium glass laser in a single intelligent platform. This dual-wavelength system delivers precise layer-specific treatment—1927nm for epidermal micro-ablation and 1550nm for deep dermal remodeling.
Three specialized treatment modes—Standard Fractional, Sliding Mode, and Private Mode—provide unmatched clinical versatility. The unique synchronized beam emission enables simultaneous epidermal and dermal treatment in a single pass, maximizing efficacy while minimizing procedure time. Three interchangeable handpieces (5mm, 10mm, 20mm) ensure optimal energy delivery across all anatomical sites.
Applications
1550nm Mode – Dermal Remodeling (Non-Ablative)
Atrophic Acne Scar Revision Stimulates neocollagenesis deep within dermis, remodeling rolling, boxcar, and icepick scars through controlled thermal injury zones.
Fine Lines & Wrinkles Reduction Gentle dermal heating smooths periorbital, perioral, and forehead rhytides by inducing new collagen and elastin production.
Surgical & Traumatic Scar Improvement Softens and flattens hypertrophic and normotrophic scars through progressive dermal remodeling over 3-5 treatment sessions.
Skin Laxity & Elasticity Enhancement Tightens loose facial and body skin by stimulating dermal matrix contraction and neocollagenesis.
Enlarged Pore Refinement Reduces visible pore size through perifollicular collagen remodeling and sebaceous gland modulation.
Striae Distensae (Stretch Marks) Improvement Treats both red and white stretch marks by stimulating dermal regeneration in atrophic areas.
Comprehensive Photoaging Correction Simultaneously ablates photodamaged epidermis while stimulating deep dermal collagen—addressing both surface and structural aging in one pass.
Mixed-Type Melasma Treats both epidermal and dermal pigment components simultaneously, improving outcomes in refractory melasma cases.
Deep Acne Scars with Surface Irregularities Combines deep dermal remodeling for atrophic scars with superficial smoothing for associated texture abnormalities.
Maximum-Impact Rejuvenation Delivers full-thickness treatment in fewer sessions—ideal for patients seeking dramatic results with limited downtime.
Periorbital & Perioral Comprehensive Rejuvenation Addresses both fine lines (dermal) and surface texture/pigmentation (epidermal) in delicate anatomical zones.
Body Area Transformation Treats chest, neck, and hands with combined epidermal brightening and dermal tightening for comprehensive photodamage correction.
Working Principle
The 1,927 nm thulium wavelength is strongly absorbed by water in the epidermis, creating controlled micro-ablative zones that remove superficial pigmentation, smooth texture irregularities, and treat actinic damage with minimal thermal diffusion to surrounding tissue.
The 1,550 nm erbium glass wavelength penetrates deeper into the dermis, generating microscopic thermal zones (MTZs) that stimulate neocollagenesis and elastogenesis through controlled wound healing response while preserving the epidermal barrier.
In synchronized mode, 1927nm creates superficial micro-channels that temporarily reduce epidermal impedance, allowing 1550nm energy to reach deeper tissues with enhanced efficiency. This synergistic delivery achieves full-thickness treatment—from epidermal surface to deep dermis—in a single pass.
Clinical Support
Proven Efficacy Across Indications
Clinical studies demonstrate consistent improvement with 1550nm for scarring and melasma, and 1927nm for photoaging and pigmented lesions—supported by histologic evidence of dermal remodeling and reduced melanin after treatment.
Superior Safety for Skin of Color
The dual-wavelength system is safe and effective in Fitzpatrick III–VI patients, with integrated cooling reducing epidermal heat buildup and adjustable parameters enabling data-driven protocols that minimize PIH risk.
Histologically Verified Remodeling
Within 24 hours, microscopic necrotic debris forms; by Day 7, complete epidermal regeneration occurs with increased type III collagen; at 3 months, dermal remodeling is complete with increased elastic fibers and hyaluronic acid deposition.
Versatile Treatment Platform
Over 15 years of clinical evidence supports both wavelengths independently, enabling personalized protocols based on treatment area, skin type, and individual risk factors.
