Light therapy, as a non-invasive treatment modality, has been widely adopted in the medical aesthetics industry. Evolving from professional-grade medical equipment to today’s portable consumer products, light therapy technology has experienced significant development and market penetration.

Evolution of Light Therapy Technology

The history of light therapy dates back to the 1960s, when Hungarian scientist Endre Mester first discovered the positive effects of low-level laser therapy on tissue healing. With the maturation of LED technology and decreasing costs, light therapy devices have gradually moved from the laboratory to clinical settings and, ultimately, to consumer markets.

Market Demand Analysis

According to a Global Market Insights report, the global light therapy device market is projected to grow from $820 million in 2023 to $1.56 billion by 2030, with a CAGR of 9.7%. Key growth drivers include:

• Increasing consumer demand for non-invasive beauty treatments
• The rise of home care trends
• Continued decline in LED technology costs
• Accumulation of robust clinical research evidence

Product Positioning

This 3-in-1 light therapy device is positioned as a "professional-grade portable multifunctional beauty device," aiming to deliver clinic-level results in daily life. It integrates three different LED wavelengths and two electrical therapy features, forming a complete beauty care ecosystem.

Triple-Wavelength Light Therapy

Red Light Therapy (650nm)

Penetration Depth: 1–2mm, primarily targeting epidermis and superficial dermis
Biological Effects:

• Activates cytochrome c oxidase (CCO), promoting ATP production
• Stimulates fibroblast proliferation and collagen synthesis
• Enhances blood circulation and metabolism
• Anti-inflammatory, reduces skin inflammation

Clinical Applications:

• Anti-aging: reduces fine lines and wrinkles
• Wound healing: accelerates skin repair
• Acne treatment: reduces inflammation and promotes healing
• Pigmentation: improves uneven skin tone

Green Light Therapy (520nm)

Penetration Depth: 0.5–1mm, mainly acts on the epidermis
Biological Effects:

• Highly absorbed by melanin and hemoglobin
• Suppresses melanocyte activity
• Improves microcirculation, reduces redness
• Calms and soothes sensitive skin

Clinical Applications:

• Pigmentation: reduces melasma and freckles
• Redness: improves facial capillary dilation
• Uneven skin tone: brightens complexion
• Sensitive skin: soothes allergic reactions

Near-Infrared Therapy (940nm)

Penetration Depth: 3–5mm, reaching deeper dermis and subcutaneous tissue
Biological Effects:

• Deep tissue heating, promotes circulation
• Stimulates deep collagen remodeling
• Promotes lymphatic drainage, reduces edema
• Activates stem cells for regeneration

Clinical Applications:

• Deep anti-aging: improves deep wrinkles
• Firming: enhances skin elasticity
• De-puffing: facilitates lymphatic detox
• Muscle relaxation: relieves facial tension

EMS (Electrical Muscle Stimulation) Technology

EMS uses microcurrents to stimulate facial muscles, providing non-exercise muscle training.

How It Works:

• Specific frequency currents (typically 1–100Hz) stimulate muscle contraction, simulating natural movement
• Benefits:
  1. Enhances muscle tone and strength
  2. Improves blood flow
  3. Lifts facial contours
  4. Prevents muscle atrophy

Settings:

• Frequency: 1–50Hz adjustable
• Pulse Width: 50–300μs
• Intensity: 10 levels adjustable
• Treatment Time: 5–15 min

Iontophoresis (Microcurrent Infusion) Technology

Iontophoresis uses low-level current (0.1–0.5mA/cm²) to deliver active skincare ingredients deeper into the skin by repelling charged molecules into deeper layers.

• Increases ingredient penetration
• Improves absorption
• Extends retention time in the skin
• Reduces the skin’s barrier effect

Suitable Ingredients:

• Vitamin C (antioxidant, whitening)
• Hyaluronic Acid (moisturizing, anti-aging)
• Collagen (firming, repair)
• Niacinamide (oil control, pore minimizing)

Photobiomodulation (PBM) Mechanism

At the Molecular Level:

• Mitochondrial Activation: Photons absorbed by cytochrome c oxidase increase ATP production and cellular metabolism
• Signal Pathways: Activates transcription factors (e.g., NF-κB), upregulates growth factor expression, promotes cell proliferation and differentiation
• Gene Expression: Upregulates collagen synthesis, downregulates inflammatory gene expression, modulates cell cycle genes

At the Tissue Level:

• Angiogenesis: Promotes new blood vessel formation and nutrient delivery
• Collagen Remodeling: Stimulates type I collagen synthesis, improves fiber arrangement, boosts elasticity
• Inflammation Regulation: Decreases pro-inflammatory factors, increases anti-inflammatory mediators, accelerates inflammation resolution

Dose-Response Relationship

Follows a biphasic dose-response:

• Low Dose: Promotes cell proliferation and repair
• Moderate Dose: Optimal therapeutic effect
• High Dose: May cause inhibition

Key Parameters:

• Irradiance: 20–50mW/cm²
