How many types of laser hair removal machines are there?
Now hair removal is the most acceptable medical beauty program for women. Everyone likes to be smooth as jade. There are many hair removal machines. Best for permanent hair removal? Let's take a look at which hair removal machines are there and what are the differences.
1. Long-pulse ruby laser: The wavelength is 694nm, which is the shortest wavelength in clinical hair removal lasers. The laser energy is easily absorbed by the melanin in the epidermis, resulting in relatively many adverse reactions, so it is most suitable for patients with dark hair and fair skin. . It is not suitable for people with darker skin in the yellow race, and the pain is more obvious and there is a possibility of burns.
Suitable for: patients with dark hair and fair skin
2. Long Pulse Alexandrite Laser:
With a wavelength of 755nm, it is the most widely used laser hair removal device in clinical practice. The selectivity for skin color is relatively low, and the adverse reactions are mild. The erythema and papules that appear after surgery can be relieved by cold compresses. It is a treatment device with high safety factor for hair removal treatment. 3. Long pulse width Nd: YAG laser: wavelength 1064, which has been proved to have obvious hair removal effect, especially for thick black hair. In addition to edema and pain during treatment, the incidence of other adverse reactions such as pigment changes is very low, especially suitable for patients with dark skin.
Suitable for: Coarse black hair
3. Long pulse width Nd: YAG laser: wavelength 1064, which has been proved to have obvious hair removal effect, especially for thick black hair. In addition to edema and pain during treatment, the incidence of other adverse reactions such as pigment changes is very low, especially suitable for patients with dark skin.
Suitable for: Coarse black hair
Manufacturer of laser hair removal equipment: YAG is yttrium aluminum garnet as a laser generator with a wavelength of 1064, suitable for people with light skin and dark hair. At present, few people use this instrument for hair removal.
Ultra-picosecond is also a wavelength of 1064, but it is not a long pulse width, so q1064 (ultra-picosecond) cannot be used for hair removal.
4 Intense Pulsed Light (IPL):
An intense pulsed light (IPL) device is a non-continuous, multi-wavelength combination light source that is essentially an incoherent ordinary light rather than a laser. The wavelength is 500 to 1200 nm. Using the synergistic effect of electric energy and light energy, the heat energy of electric energy is concentrated on the hair follicle and dermal papilla, and the heat energy of light energy is concentrated on the hair shaft, so that both the hair shaft and the hair follicle are destroyed to achieve the effect of hair removal. Selectivity is worse than laser. He is hesitant that Asians have darker skin than Caucasians and that IPL tends to cause hyperpigmentation or hypopigmentation. However, the pain degree during treatment is relatively small, and the operation is fast and convenient due to the large spot size, and the depth of action can be adjusted through the selection of optical filters (645, 695, 755), and the treatment cost is low.
Laser hair removal equipment manufacturers: At present, informal medical institutions such as personal studios or beauty salons basically choose to use photon hair removal methods to attract customers. For a few yuan hair removal experience, they generally choose cheap beauty salons without medical qualifications version of the so-called IPL hair removal device.
Compared with all hair removal methods, IPL takes the longest time to remove hair, usually about 6-12 times.
5. Semiconductor laser hair removal equipment
The semiconductor laser hair removal machine is one of the most clinically used laser hair removal systems, with a wavelength of 800nm or 810nm. In terms of wavelength, hair follicle melanin has relatively strong light absorption in this band, which can effectively destroy hair follicles; epidermal melanin absorbs less energy from semiconductor lasers, so it has advantages in hair removal treatment for dark skin. At present, the mainstream hair removal method has been clinically applied, and the effect is obvious, and the customer experience is better.
Are home hair removal devices reliable?
Home hair removal device: generally use IPL technology. Since household hair removal devices are generally imported brands, they are designed with European and American parameters. Because Asians have relatively few hairs and have darker skin than Europeans, once the pores absorb strong light, the burning sensation is obvious. In addition, the home hair removal device lacks professional guidance. The leaked strong light is harmful to the eyes, and the publicity is suspected of exaggeration. A certain brand publicity stunt "can be used for unlimited continuous hair". . The IPL will end its life after tens of thousands of times of use, and the light emitted by it will have no energy. Before then, the lamp head should have been reimbursed long ago. Many customers have reported that the experience is poor, and the severe cases are suspected to be red, swollen and burnt.
Manufacturers of laser hair removal equipment: In recent years, various household medical beauty equipment has been sold very well. Consumers will think that they can enjoy the achievements of medical beauty technology progress at home, and can avoid the big pit of irregular sales of medical beauty, but these Once the instrument enters the home, for safety, the energy is turned down, and it cannot achieve the proper function and effect. Irregular use and improper use by people who do not have any medical cosmetic foundation may also induce other side effects, which are not worth the harm. In the end, most people get it in three minutes, and it will be put on the shelf after a few days. The state of abandoning it is actually a waste of money.
Freezing point hair removal: Freezing point is not a hair removal technology, but a cooling technology used in the process of hair removal to improve the pain caused by the thermal stimulation of the skin by laser or IPL.
Vacuum hair removal: Vacuum is not a hair removal technology. It is only in the process of hair removal. Vacuum technology is used to inhale the part of the hair to be removed, so that light waves or heat can enter the hair follicles of the skin more accurately, avoiding the impact on the surrounding skin. Conclusion: There are many ways to remove hair. These methods can eventually remove the hair to an inconspicuous state. The key is time. Generally speaking, hair has a resting period and a growing period. No matter which hair removal method is used, it only affects the hair in the growing period. The effect, so persistence is a must. You must not take off your hair once, if you don’t go for two months, then go again in the third month, it will never be clean.
Manufacturers of laser hair removal equipment: Any hair removal method has the benefits of rejuvenating the skin. This is also a good buy-one-get-one-free item. Although everyone may say that they don't care whether the skin on the body is smooth and white, But inadvertently the skin is getting better and better and whiter.
Human aging is related to UV exposure. The older the person, the more obvious melanin in the skin. Not only the face has melanin, but all the skin on the body will have melanin pigmentation. Therefore, the benefits of hair removal are not only smoothness, but also skin rejuvenation and beauty. Skin remove melanin effect.
