Product Description:

The working principle of laser hair removal is based on selective photothermal effect, which uses laser energy of a specific wavelength to target the melanin in the hair follicles, converting light energy into heat energy, thereby destroying the hair follicles and inhibiting hair regeneration.

Working principle

- **808nm**: Well-balanced, suitable for most skin and hair types.
- **755nm**: Ideal for light skin and fine hair, with high absorption and fast treatment.
- **940nm**: Deeper penetration, suitable for dark skin and deep hair follicles.
- **1064nm**: Deepest penetration, high safety, suitable for dark skin and coarser hair.

### **Main functions of laser hair removal machines**

1. **Hair removal**:
- The main function of laser hair removal is to target melanin in hair follicles through selective photothermal action, destroying the hair follicles and thus inhibiting hair regrowth.

### **Skin rejuvenation function**

1. **Skin smoothing and firming**:
- Some advanced laser hair removal devices combine other technologies, such as RF (radio frequency) or photon technology, which can tighten and smooth the skin while removing hair. Although these functions are not the core purpose of laser hair removal, they can provide additional skin improvement effects.

2. **Auxiliary skin rejuvenation effect of laser**:
- Some laser devices (such as long-pulsed Nd:YAG lasers) are not only used for hair removal, but also have the ability to perform deep treatments on the skin. This laser can promote the self-repair and regeneration of the skin, thereby improving the skin's texture and elasticity to a certain extent.

3. **Comprehensive treatment equipment**:
- Some multifunctional beauty devices may include laser hair removal and skin rejuvenation functions. For example, some high-end devices are equipped with multiple modules or handles, which can perform multiple treatments such as hair removal, skin rejuvenation, and freckle removal on the same device.

Product details:

The 940nm wavelength laser is suitable for dark skin hair removal because its properties make it more suitable for treating darker skin tones and deeper hair follicles.

Applications:

### **Safety of laser hair removal**

1. **Equipment quality and operation**

- **Regular equipment**: Choosing a certified, high-quality laser hair removal device can reduce the risk of adverse reactions. Modern laser devices are usually equipped with a cooling system to protect the skin from overheating.

- **Professional operation**: Operated by trained professionals, they can ensure that the laser energy settings and treatment plans are suitable for the patient's skin color and hair type, reducing the possibility of side effects.

2. **Cooling technology**

- **Skin protection**: Many laser hair removal devices are equipped with cooling systems (such as sapphire cooling windows or cold air jets) to help reduce discomfort during treatment and protect the surface of the skin.

3. **Skin type and hair**

- **Personalized adjustment**: Modern devices allow the laser wavelength and energy settings to be adjusted according to skin type and hair color, thereby improving safety and effectiveness.
