Working principle
The four-wavelength laser hair removal machine usually includes the following four common wavelengths:

1. **755nm (Alexandrite laser)**
- **For light skin and fine hair**: Mainly absorbs melanin in hair follicles, especially suitable for hair removal of light skin and fine and soft hair.

2. **808nm (semiconductor laser)**
- **Multi-function wavelength**: Energy penetration is deeper, suitable for most skin types and hair types, balancing the effect and treatment speed.

3. **940nm**
- **Deep penetration and low side effects**: Deeper penetration than the 808nm wavelength, better effect on dark hair, while reducing damage to the epidermis, suitable for sensitive skin and dark skin.

4. **1064nm (Nd:YAG laser)**
- **Dark skin and deep hair**: Strongest penetration, suitable for dark skin and thicker hair, can effectively reduce pigmentation and burn risks.

### Palladium Rod
- **Enhancing Components**: Palladium rods are often used in the core components of lasers as part of the enhancing device. It helps improve the efficiency and stability of the laser, ensuring that the laser beam can continuously emit high-energy photons to effectively target and destroy melanin in hair follicles.
- **Thermal Stability**: Palladium is a precious metal with good thermal stability, which means it can maintain stable performance in the high temperature environment of the laser, thereby extending the life of the laser and improving the quality of the output energy.

### Sapphire
- **Cooling and Protective Effect**: Sapphire crystals are often used as contact cooling windows for laser hair removal devices, directly in contact with the skin. Sapphire has extremely high thermal conductivity, which can quickly remove excess heat from the skin surface, reduce the risk of burns, and provide a cooling effect to improve comfort during treatment.
- **Optical Transmission**: Sapphire crystals have excellent optical transmission properties, which can effectively transmit laser energy while protecting the skin from high temperature damage of the laser. Its transparency ensures that the laser energy can be accurately delivered to the hair follicles deep in the skin.
- **Durability**: Sapphire crystals are very hard (second only to diamonds) and can resist scratches and wear, ensuring that the device maintains efficient optical performance during long-term use.

Applications:

Laser hair removal machines have several advantages in terms of hair removal and treatment effects, as follows:

### 1. **Long-lasting**
- **Destroy hair follicles**: Laser hair removal generates heat and destroys hair follicles by focusing laser energy on the melanin in the hair follicles. This destruction inhibits hair regrowth, allowing the hair removal effect to last longer, and it usually takes multiple treatments to completely remove hair.

### 2. **Precision**
- **Targeted melanin**: Laser energy is mainly absorbed by the melanin in the hair follicles, causing less damage to the surrounding skin. This precision makes laser hair removal particularly suitable for removing hair in specific areas, such as the face, underarms, bikini line, etc.
- **Suitable for different types of hair**: Lasers of different wavelengths (such as 755nm, 808nm, 1064nm) can provide customized treatments for hair of different thicknesses and colors.

### 3. **Fastness**
- **Large-area treatment**: Laser hair removal can cover a large skin area in a short time, so it is suitable for areas that require large-area hair removal, such as legs and back. Each laser pulse can treat multiple hair follicles, reducing treatment time.

### 4. **Comfort**
- **Advanced cooling technology**: Many laser hair removal devices are equipped with cooling systems, such as sapphire cooling windows, which can protect the skin during treatment, reduce pain and discomfort caused by heat, and improve the comfort of treatment.

FAQ:

### 1. **What is the principle of laser hair removal? **
- **Answer**: Laser hair removal targets melanin in hair follicles through laser energy of a specific wavelength, destroying the structure of the hair follicles and inhibiting hair regeneration.

### 2. **Is laser hair removal safe? **
- **Answer**: Laser hair removal is safe under normal operation. Modern equipment is usually equipped with a cooling system to protect the epidermis and reduce side effects such as burns and pigmentation.

### 3. **Is laser hair removal effective for all skin types? **
- **Answer**: Lasers with different wavelengths are suitable for different skin types and hair types. Modern four-wavelength laser hair removal devices can provide customized treatments for various skin colors and hair.

### 4. **How ​​many treatments are needed for laser hair removal? **
- **Answer**: Usually 6 to 8 treatments are required because hair growth has different cycles and laser hair removal works best during the growth period. The number of treatments depends on the individual's hair condition.

### 5. **Will laser hair removal hurt? **
- **Answer**: You may feel a slight sting during treatment, but most devices are equipped with a cooling system to reduce discomfort.

### 6. **What are the side effects of laser hair removal? **
- **Answer**: Common side effects include temporary redness, stinging, and slight pigmentation after treatment, which usually subside within a few hours to a few days. Serious side effects such as blisters and scars are extremely rare.

### 7. **Is laser hair removal permanent? **
- **Answer**: Laser hair removal can significantly reduce hair regrowth, but it is difficult to completely and permanently remove all hair. Most people can achieve long-term hair reduction after multiple treatments.

### 8. **What should I pay attention to after laser hair removal treatment? **
- **Answer**: Avoid sun exposure, use gentle skin care products, avoid strenuous exercise to reduce skin irritation, and keep the treated area clean.

### 9. **What are the advantages of laser hair removal compared to other hair removal methods? **
- **Answer**: Laser hair removal is long-lasting, safe, and highly targeted, suitable for large-area treatment. Compared with traditional methods such as shaving, plucking, and waxing, it is more convenient and reduces the problem of hair regrowth.

### 10. **What are the differences between lasers of different wavelengths? **
- **Answer**: Lasers of different wavelengths have different absorption levels of melanin and skin penetration, so they are suitable for different skin and hair types. For example, 755nm is suitable for light skin and fine hair, while 1064nm is suitable for dark skin and coarse hair.
