LEDs work on the principle of Electroluminescence. On passing a current through the diode, minority charge carriers and majority charge carriers recombine at the junction. On recombination, energy is released in the form of photons.

In this era of pursuing efficient skin care, beauty lamps have become the new favorite of skin care experts with their "light therapy black technology"! But do you know? What really determines the effectiveness of the lamps are those seemingly tiny but energetic LEDs. Today, let's take a look at it - how different wavelengths of light can accurately target skin problems!

## Precise skin care mechanism of monochromatic light

Modern phototherapy beauty uses LED light of different wavelengths to penetrate the skin layers and trigger photobiomodulation:

Red light (620-660nm)**: Penetrates into the dermis and stimulates fibroblasts to produce type I collagen. Clinical studies have shown that it can reduce wrinkle depth by 36%

Blue light (460nm)**: By activating porphyrin to produce singlet oxygen, it effectively kills Propionibacterium acnes and improves inflammatory acne by 76%

- **Yellow light (590nm)**: Targets mast cells to stabilize membrane structure, reduces histamine release, and reduces erythema index by 42%

- **Green light (520nm)**: Inhibits tyrosinase activity, reduces melanin synthesis, and uses red light to improve pigmentation by 2 times

## Principle of compound light synergistic enhancement

1. **Red and blue light combination**: Coordinated regulation through the PPAR-γ pathway, reducing inflammatory factor TNF-α and promoting TGF-β1 secretion

2. **Infrared light composite system**: 850nm and 1064nm form a deep gradient stimulation, which promotes microcirculation (blood flow rate increased by 58%) and collagen remodeling (density increased by 29%)

## Key parameters of lamp bead technology

| Model | Wavelength combination | Light power density | Applicable scenarios |
|------|----------|------------|----------|
| 5050RGBYOC | 5-color mixing | 80-120mW/cm² | Full-effect care |

Three-in-one LED diode:

Integrated red light (630nm), blue light (450nm) and infrared (850nm/940nm/1064nm) three wavelengths. Suitable for treating a variety of skin problems, such as anti-aging, acne removal and deep care.

Four-in-one LED s:

Integrated red light, blue light, green light (520nm) and infrared light four wavelengths. Green light is added to effectively improve spots and brighten skin tone, suitable for all-round care.

‌Five-in-one LED light:

Yellow light (590nm) is added on the basis of four-in-one, further expanding the phototherapy function, suitable for high-demand care needs.

Mixed light: a smart combination of 1+1＞2

When monochromatic light joins forces, the skin care effect is fully upgraded:

Red and blue CP: anti-inflammatory + repair, a golden partner for sensitive skin stabilization.

Blue light (440-480nm): awaken skin energy, accelerate metabolism and renew.

Purple light (280-400nm): cell power bank, specially for staying up late and dull skin!

Special light: deep healing that penetrates the bottom of the skin

Infrared light (830-950nm)

Promote microcirculation, improve chronic damage, and do "Thermage" for the skin.

Long infrared light (1064nm)

Directly hit the dermis, stimulate collagen regeneration, and fine lines have nowhere to hide!

Choose the right lamp beads = customize your own skin care plan

The mainstream large row of lamps on the market are often equipped with 5050RGBYIR five-color lamp beads (red/green/blue/yellow/infrared), which can achieve the following through intelligent combination:

Anti-aging and light lines Oil control and acne removal Whitening and brightening Soothing and repairing

**Usage precautions**: It is recommended to irradiate for 15-20 minutes each time, 20-30cm away from the face, and sensitive skin should avoid continuous use for more than 10 minutes. Clinical data show that after 8 weeks of standardized use, skin elasticity is increased by 27% and the recurrence rate of acne is reduced by 63%.
