GMKJ Medical Aesthetic & Therapeutic LED Light Sources
Wavelength Reference Guide and Application Overview
The following wavelength reference guide is compiled by GMKJ based on industry standards, published research, clinical consensus, and customer-provided studies.
This document is intended solely for product development, equipment design, and LED source selection reference. It does not constitute medical advice, clinical treatment recommendations, efficacy guarantees, or regulatory claims.
All medical applications require appropriate clinical validation, regulatory approval, and compliance with local medical device regulations.
1. Ultraviolet Spectrum (200nm–400nm)
| Wavelength Range | Typical Wavelengths | Primary Medical & Aesthetic Applications | Notes |
|---|---|---|---|
| UVC (200–280nm) | 254nm, 265nm | High-efficiency sterilization and disinfection by damaging bacterial and viral DNA; surface wound disinfection and infection control | Limited penetration depth, primarily affecting the epidermal layer. Not typically used for cosmetic skin rejuvenation. |
| UVB (280–320nm) | 308nm, 311nm | Treatment of psoriasis and vitiligo; stimulation of melanin production; promotion of Vitamin D synthesis | Narrowband UVB (311nm) is widely recognized as a first-line dermatological treatment. Dose control is critical to avoid skin damage. |
| UVA (320–400nm) | 365nm, 405nm | Photodynamic Therapy (PDT); acne treatment; vascular lesion treatment; adjunct treatment for psoriasis | Penetrates deeper into the dermis. Long-term exposure may contribute to photoaging. Proper protection is required. |
2. Visible Light Spectrum (400nm–700nm)
Violet & Blue-Violet Light (400–450nm)
| Wavelength | Applications |
|---|---|
| 415nm, 430nm | Anti-inflammatory treatment, acne bacteria suppression, sebum regulation, redness reduction, sensitive skin support |
Key Benefits
- Inhibits Cutibacterium acnes (formerly Propionibacterium acnes)
- Reduces inflammatory acne lesions
- Helps calm irritated and sensitive skin
- Commonly used in professional acne therapy systems
Blue Light (450–495nm)
| Wavelength | Applications |
|---|---|
| 460nm, 470nm | Acne treatment, sebaceous gland regulation, skin inflammation management |
Key Benefits
- Targets acne-causing bacteria
- Reduces excess oil production
- Minimizes recurrence of inflammatory acne
- Widely used in IPL and phototherapy devices
Green Light (495–570nm)
| Wavelength | Applications |
|---|---|
| 530nm, 550nm | Post-treatment recovery, redness reduction, sensitive skin care |
Key Benefits
- Calms irritated skin
- Reduces redness and discomfort
- Supports recovery after aesthetic procedures
- Improves skin balance and comfort
Yellow Light (570–590nm)
| Wavelength | Applications |
|---|---|
| 590nm | Skin brightening, circulation enhancement, lymphatic drainage support |
Key Benefits
- Improves microcirculation
- Reduces edema and inflammation
- Enhances skin radiance
- Helps improve visible capillaries and skin sensitivity
Orange Light (590–620nm)
| Wavelength | Applications |
|---|---|
| 605nm | Pigmentation management and skin tone improvement |
Key Benefits
- Helps reduce hyperpigmentation
- Improves uneven skin tone
- Promotes epidermal renewal
- Often combined with yellow light therapy
Red Light (620–700nm)
| Wavelength | Applications |
|---|---|
| 630nm, 640nm, 660nm | Tissue repair, collagen stimulation, anti-aging treatment |
Key Benefits
- Promotes collagen production
- Supports wound healing
- Reduces inflammation and redness
- Improves skin elasticity
- Helps reduce fine lines and acne scars
Red light therapy remains one of the most widely utilized wavelengths in both dermatology and medical aesthetic applications.
3. Near Infrared Spectrum (700nm–2500nm)
NIR-I Region (700–1000nm)
| Wavelength | Applications |
|---|---|
| 810nm, 830nm, 850nm, 880nm, 940nm | Deep tissue therapy, pain relief, circulation improvement, anti-aging |
Key Benefits
- Penetrates into dermal and subcutaneous tissue
- Supports muscle recovery and joint comfort
- Promotes wound healing
- Stimulates deep collagen remodeling
- Supports hair growth therapy
Among these wavelengths, 810nm–850nm are considered highly effective due to strong absorption by Cytochrome C Oxidase (CCO), making them popular choices for PBM (Photobiomodulation) and therapeutic devices.
NIR-II Region (1000–2500nm)
| Wavelength | Applications |
|---|---|
| 1064nm, 1320nm, 1550nm | Skin tightening, collagen remodeling, scar treatment, body contouring |
Key Benefits
- Deep dermal thermal stimulation
- Non-invasive skin rejuvenation
- Reduction of wrinkles and skin laxity
- Improvement of acne scars and enlarged pores
- Fat reduction and body contouring applications
1064nm is also widely utilized in laser hair removal and pigmentation treatment systems.
4. Mid-Infrared Spectrum (2500nm–3000nm)
| Wavelength | Applications |
|---|---|
| 2790nm, 2940nm | Skin resurfacing, scar treatment, wrinkle reduction, thermal therapy |
Key Benefits
- Precise epidermal and superficial dermal ablation
- Treatment of acne scars and pigmentation
- Skin rejuvenation with shorter recovery periods
- Thermal therapy for muscle relaxation and circulation enhancement
The 2940nm Er:YAG laser remains one of the most commonly used wavelengths in advanced aesthetic resurfacing systems.
Important Application Notes
Clinical Performance Depends on Multiple Factors
Therapeutic outcomes are determined not only by wavelength, but also by:
- Optical power
- Irradiance (Power Density)
- Treatment duration
- Pulse parameters
- Tissue penetration depth
- Device design
Wavelength alone does not determine clinical effectiveness.
Safety Considerations
- UVC and UVB systems require professional operation and strict exposure control.
- Near-infrared and mid-infrared systems must be carefully designed to avoid excessive thermal effects.
- Protective measures should always be implemented according to local regulations and clinical protocols.
