Precision 308nm Excimer Light System for Psoriasis, Vitiligo and Chronic Skin Conditions
The AS-308 Excimer Therapy Device delivers targeted 308nm excimer light therapy for dermatological treatment. Using xenon-chloride excimer technology, it emits a high-energy monochromatic UVB beam to achieve precise, localized phototherapy.
Product Overview
The AS-308 Excimer Light Therapy Device is a professional-grade 308 nm UVB treatment system designed for targeted phototherapy of chronic skin conditions.
It delivers precise and controlled monochromatic light for localized treatment, offering clinical efficacy in managing psoriasis, vitiligo, eczema (atopic dermatitis), seborrheic dermatitis, and leukoderma.
The AS-308 combines medical-grade excimer technology with compact design and easy operation, making it suitable for both home and professional dermatology applications.
Principle
The AS-308 uses 308nm excimer light within the UVB spectrum to deliver precise, targeted phototherapy. This wavelength effectively treats skin lesions without damaging surrounding healthy tissue. It works by modulating immune activity, stimulating melanocyte regeneration, and reducing inflammation, helping restore pigmentation in vitiligo and alleviate symptoms of psoriasis.
Features
-
Targeted therapy – precisely treats affected areas without damaging surrounding skin.
-
High energy & efficiency – faster therapeutic results compared with conventional phototherapy.
-
Non-invasive & safe – no systemic side effects, suitable for sensitive skin areas.
-
Flexible handpiece design – convenient operation and accurate irradiation.
Treatment Modes & Spot Options
The AS-308 features multiple spot sizes and adjustable parameters for precise, personalized therapy:
- Small Spot (Ø10 mm / 10×10 mm): For facial or small lesions; accurate and skin-safe.
- Medium Spot (Ø20 mm / Ø30 mm): For arms, legs, or mid-sized patches.
- Large Spot (Ø40 mm / 25×25 mm): For large areas like the back; faster coverage.
Each mode supports adjustable time (1–140s) and energy (up to 5 J/cm²). A built-in MED test mode ensures accurate, safe dosage for each user.
Applications
- Vitiligo (Leukoderma) – stimulates pigment regeneration
- Psoriasis (including scalp type) – controls keratinocyte overgrowth
- Eczema & Atopic Dermatitis – relieves inflammation and itch
- Seborrheic Dermatitis, Neurodermatitis, and other localized lesions
