The laser in the hair removal device penetrates the skin epidermis and reaches the hair follicles. The melanin in the hair follicles absorbs laser light energy, producing a photothermal effect. Light energy is converted into heat energy, and the temperature of the hair follicles rapidly increases. The hair follicles solidify and necrosis, thereby removing hair. The laser of the hair removal instrument mainly includes: 1. Laser: Strictly speaking, laser is what beauty salons usually refer to. Usually used by professional medical beauty hospitals, household hair removal machines are not commonly used because their oversized characteristics are that laser hair removal is very painful and the safety performance is relatively low. 2. IPL: Strong pulsed light and photons. After irradiation on the skin, it can close abnormal pigments, damage hair follicles, stimulate collagen regeneration, and other beauty effects. Initially used for whitening and dispelling Treatment for blemishes, skin tightening, etc. Nowadays, it is used by household hair removal equipment to remove body hair while also achieving a skin rejuvenation effect. 3. HPL: Home light laser hair removal technology is a laser developed in Israel for household use. The same principle as IPL. When light waves irradiate tissues, the pigments on the hair selectively absorb most of the light waves, while the surrounding tissues are not heated. The melanin on hair is responsible for absorbing light waves and generating heat energy. Finally, the effect of stopping hair growth is achieved. It is currently a relatively fast and effective hair removal technology 4. ELOS: That's what we call E-light. It is a new technology that combines IPL and bipolar radio frequency (a commonly used technology in beauty equipment), selectively synergistically acting on the skin to remove hair and rejuvenate the skin. The combination of IPL and radiofrequency for hair removal treatment has been proven to be safe and effective, and its efficacy is 20% higher than that of IPL alone.

1. Early shaving The day before using the hair removal device, it is necessary to scrape off the hair on the epidermis first. Otherwise, the light from the hair removal device cannot reach the root of the hair follicle, which will directly affect the hair removal effect. Additionally, there will be an unpleasant smell of burnt hair when using the hair removal device 2. Vertical skin When using the hair removal device, it is necessary to align the light outlet with the area to be removed and stick it vertically against the skin. If it is not fully attached or not vertical enough, it may cause light leakage and damage to the eyes. 3. Avoid repetition When using a hair removal device, it is important not to repeatedly irradiate the same area multiple times, as this can cause damage to the skin and may cause redness or water dogs. 4. Avoid tattoos If there are tattoos or wounds, it is important to avoid them. This area cannot be depilated because the principle of the hair removal device is to allow light energy to act on the melanin in the hair follicles to hypnotize them. However, tattoos or darker skin areas will accumulate a large amount of melanin, so using the hair removal device will affect the skin itself. 5. Pay attention to sun protection Pay attention to strengthening sun protection after releasing. To prevent the detachment area from turning black due to pigment deposition. So the best time to release can be early spring. If you want to release in summer, be sure to put on sunscreen and an umbrella when going out.

Mainly based on instrument wavelength The hair removal instruments used in clinical practice have a wavelength range of 694-1200m, which can be well absorbed by melanin in the hair follicles while ensuring its penetration depth into the hair follicles. From the perspective of therapeutic effects, the efficacy of semiconductor lasers and various strong pulse lights is basically similar. Under the same treatment frequency, the efficacy of long pulse Nd: YAG lasers may be slightly worse than that of semiconductor lasers and strong pulse lights. The ideal pulse width range for pulse width laser hair removal is 10-100ms or even longer, and it can even increase to hundreds of milliseconds for people with deep skin color, making it safer.

Freezing point hair removal adopts a new pulse mode and repetition frequency, which can increase the hair removal speed to 3-5 times the previous one through technological advantages, making large-scale hair removal more simple. It is fully computer-controlled and easy to operate, making both the operator and the user feel very relaxed. Through a specially designed dual pulse laser. Using only a lower energy density to irradiate the skin, the first laser pulse through the epidermis heats the skin tissue and hair follicles. The second pulse selectively increases the temperature of the hair follicle to around 45 degrees, and a sliding 10Hz laser ensures that the hair follicle is maintained at this temperature for a period of time. The hair follicle and growing stem cells lose their growth activity, thus achieving long-term hair removal. The biggest difference in mechanism between freezing point hair removal and traditional laser hair removal is that traditional laser hair removal requires instantaneous high-energy burning of hair follicles, while freezing point hair removal gently causes hair follicles to automatically lose activity. Therefore, it can achieve long-term hair removal without excessively stimulating the skin to avoid pain or risk.

1. Inflammation and wound conditions If you want to perform freezing point hair removal, you need to determine if there are wounds or inflammation in the hair removal area. Freezing point hair removal is not suitable for situations with wounds and inflammation. 2. People with photoallergic skin are not suitable for freezing point hair removal For photoallergic skin. Not only is it not suitable for freezing point hair removal, but all laser, color light and other projects are not suitable for people with photosensitive skin to avoid causing allergic reactions such as erythema and itching. 3. Pregnant women are not suitable for freezing point hair removal Freezing point hair removal is not harmful to both pregnant women and fetuses. To avoid miscarriage due to stress or other psychological factors, it is recommended that pregnant women do not undergo freezing point hair removal during pregnancy.
