（Core Technologies）

1. Multi-module Synergy Technology: Adopting an intelligent interface integration system, the four handpieces (808nm laser, IPL, Nd:YAG picosecond, and RF) can be quickly plugged, unplugged, and switched. The device automatically identifies the handpiece type and matches the exclusive working mode, eliminating the need for repeated parameter adjustment and improving diagnosis and treatment efficiency.

2. 808nm Precision Hair Removal Technology: Equipped with an imported high-power diode laser source, the wavelength stability error is ≤±2nm. The energy is concentrated with moderate penetration depth (up to the superficial dermis), which can accurately act on hair follicle target tissues while avoiding epidermal damage. It is suitable for people with skin types Ⅰ-Ⅵ.

3. IPL Broad-Spectrum Skin Rejuvenation Technology: With a wavelength range of 530-1200nm, it can selectively act on epidermal pigments and capillaries, improving problems such as freckles, sunspots, and telangiectasia. At the same time, it stimulates collagen regeneration and enhances skin luster.

4. Nd:YAG Picosecond Skin Rejuvenation Technology: Offering dual-wavelength options (1064nm/532nm) and a picosecond-level pulse width (≤700ps), it can shatter pigment particles into smaller fragments, accelerating their metabolism and excretion. It effectively improves chloasma, tattoos, and pigmentation with a short recovery period.

5. RF Firming Technology: Using monopolar RF energy, it penetrates to the dermis to generate a thermal effect, stimulating the contraction and regeneration of collagen fibers. It improves skin sagging and fine lines, and enhances facial contour and skin elasticity.

6. Intelligent Regulation and Cooling System: Equipped with a skin type detection module, it can automatically match the optimal treatment parameters for each handpiece. The dual cooling system (air cooling + water cooling) maintains the treatment head temperature at 5-10℃, reducing epidermal thermal damage and discomfort.

7. Efficient and Portable Design: The 808nm handpiece is equipped with 12×12mm and 9×9mm light spots, increasing the efficiency of large-area hair removal by 30%. The device is lightweight (about 20kg) with built-in universal wheels, facilitating flexible movement in diagnosis and treatment scenarios.

（Working Principle）

Each handpiece of the device achieves targeted aesthetic effects based on different optical and physical principles, following the core treatment logic of "precise action and minimal damage":

• 808nm Laser Handpiece: Based on the principle of selective photothermolysis, the wavelength is preferentially absorbed by melanin in hair follicles and converted into thermal energy. This raises the hair follicle temperature to above 60℃, destroying the follicle activity and achieving permanent inhibition of hair growth.

• IPL Handpiece: Utilizing the selective photothermolysis of intense pulsed light, different wavelengths are absorbed by pigments (such as freckles) and hemoglobin (such as telangiectasia) respectively. The thermal effect shatters pigments, seals abnormal blood vessels, and stimulates collagen regeneration.

• Nd:YAG Picosecond Handpiece: The picosecond-level short pulse generates a strong photomechanical effect, which vibrates and shatters pigment particles into tiny fragments. This avoids the thermal damage of traditional lasers, and the fragments are excreted through human metabolism to achieve skin rejuvenation effects.

• RF Handpiece: Based on the RF thermal effect, the energy penetrates the epidermis to act on the dermis, raising the dermis temperature to 40-45℃. This stimulates the contraction of collagen fibers, activates the activity of fibroblasts, and promotes the synthesis of new collagen, achieving firming and anti-aging effects.

Each handpiece can be used independently or in combination. For example,
