How to choose laser hair removal machine?

2022-07-21
The hair cycle of the human body is generally divided into the growth phase, the regression phase, and the resting phase. After the telogen phase, the dead hair follicle is shed and another hair follicle is born, starting a new growth cycle.

Several problems commonly encountered in hair removal.
1. Is hair removal safe?
Hair removal is a very safe hair removal method. It is highly professional, has no side effects on the human body, has almost no effect on normal skin, and has the effect of rejuvenating and firming the skin.
2. is it effective to take it off once?
After taking it off once, most people's hair will be much thinner and grow more slowly, but it usually takes about 3-5 times to completely take off.

The hair growth cycle is divided into three stages:
Growth period: The growth period lasts from 2 to 6 years, depending on different parts;
Telogen: The hair will stop growing when it enters the telogen phase, but it has not left the hair follicle;
Shedding period: During the shedding period, the old hair will fall off, and new hair will grow in the follicle at the same time.
Optical hair removal is mainly aimed at the hair in the growing period, but it does not work for the hair in the telogen and shedding period.

3. Will sweating be affected after hair removal?
Perspiration mainly depends on the eccrine glands, and the openings of the eccrine glands are not in the hair follicles. At the same time, OPT hair removal is to remove the hair follicles and will not damage the sweat glands, so it does not affect human metabolism and perspiration.
The principle of hair removal is the principle of selective photothermal: that is, the selected wavelength only acts on melanin, not on normal skin tissue.

4. Is it possible to achieve a permanent hair removal effect?
Generally speaking, after many treatments, the purpose of permanent hair removal can be achieved, of course, its efficacy is affected by many factors.

Let's talk about the difference between OPT hair removal device, 808 semiconductor hair removal device, and magneto-optical 360 hair removal device on the market:

Difference 1: Principle difference

The spectrum of DPL Precision 550 is compressed within 550~650nm while ensuring the perfect ratio of melanin absorption rate and penetration depth. When the concentrated light energy is irradiated to the skin, the pigment particles are instantly destroyed and decomposed, engulfed by phagocytes in the body, and followed by The lymphatic system drains the body. A two-pronged approach can achieve the purpose of removing melanin and freckle. (referred to as the role of the magneto-optical system).

Another iconic function of DPL 360 magneto-optical light is magneto-optical hair removal: the use of intense pulsed light selectively acts on melanocytes, the hair follicles absorb energy and are destroyed, and the hair removal effect can be achieved without damaging the normal skin.

The principle of OPT pulsed light hair removal is that intense pulsed light acts on the skin tissue to produce photothermal and photochemical effects, rearrange collagen fibers and elastic fibers in the deep skin, restore skin elasticity, and at the same time enhance the function of vascular tissue so that facial skin wrinkles can be eliminated or lightened. At the same time, it can also absorb the intense pulsed light through the hair shaft and the hair head in the hair follicle, generating heat to the hair follicle, the temperature of the hair follicle rises rapidly and necrosis, so as to achieve the effect of long-term hair removal.

Difference 2: Energy Difference
DPL hair removal and OPT hair removal are quite similar in principle, but in fact, DPL magneto-optical has three times more light sources than opt, ten times stronger energy, and more efficient efficiency.

Difference 3: technical difference
• DPL Precision Light Technology
DPL uses specially designed crystals to convert traditional photon spectral lines to yellow-green spectrum, and then applies ultra-narrowband filters to filter out stray spectra, and outputs 100nm precise light with highly concentrated energy. It is currently the most advanced skin rejuvenation technology in the world. , is also a new generation of high-end photons in the beauty market.
Compared with other traditional photons, DPL is more in line with the principle of selective photothermal action. At the same time, combined with the unique magnetic properties of the magneto-optical system, it realizes the greater absorption of light intensity by the target tissue, greatly improves the photothermal selectivity, and breaks through traditional photons. Rejuvenation limit, get more accurate and efficient skin rejuvenation effect.

• OPT intense pulsed light technology
We all know that opt ​​is a type of photon, an upgraded version of photonic skin rejuvenation such as E-light. The opt strong pulse technology is ideal at some level, but the dual system of 360 magneto-optical is an upgrade of the opt strong pulse light system. version, breaking through the shortcomings of the original OPT in some cases. More advanced skin rejuvenation and hair removal can be achieved.
Dual-mode operation: You can slide quickly, or operate at a fixed point, switch freely, and do whatever you want!

The 808 semiconductor hair removal device is a diode laser device. It uses a 15mmX15mm wide light irradiation area. The high-power 808nm wavelength laser is combined with a cooling system to improve the energy transfer effect. During operation, the damage to the skin tissue will also be minimized.

808 diode laser hair removal principle?
1. Act on the skin surface by 808nm laser. The laser is passed through the skin to the point where the melanin concentration of the hair shaft is highest.
2. The light is converted into heat energy, and the hair rods and most of the hair evaporate instantly. Then the high temperature acts on the hair and also destroys the follicular epithelium, and the upper part of the hair disappears.
3. Hair cycle - growth phase, recession phase, and dormant phase, hair follicles have the best hair removal effect during the growth phase, but only 10%-20% of the hair is in the growth phase, so it is necessary to completely remove the hair according to the course of treatment.

How to choose a hair removal and skin rejuvenation device?
The first type of OPT hair removal machine.
OPT hair removal machine (SHR+OPT dual beauty system) is an intelligent, non-ablative skin reconstruction system integrating epidermal cooling technology, perfect pulse light technology, and RF radio frequency technology. The principle of action is the same as that of freezing point hair removal. It adopts the selective photothermolysis principle of the patented intense pulsed light source and uses the melanocytes in the hair follicle to absorb the light of a specific wavelength band so that the hair follicle generates heat and selectively destroys the hair follicle. At the same time, the emitted heat can be transmitted to the deep part of the hair follicle through the cross-section of the hair shaft to rapidly increase the temperature of the hair follicle, so as to achieve the effect of removing hair while avoiding damage to the surrounding tissue. Since the hair follicle can no longer be regenerated, OPT photon hair removal is permanent. Hair removal effect.

The second category is the magneto-optical 360 DPL hair removal machine.
There are single-head and double-head configurations, but the function of the working head is fixed, one for hair removal, one for skin rejuvenation, no function extension, fool type, no laser head, no eyebrow washing, no tattoo washing and spotting Etc., it belongs to the same kind of technology upgrade instrument for OPT pulse hair removal. The advantage is that it automatically matches the light source, the light is not so dazzling, and the life of the working head is about 3 times longer than that of OPT. The disadvantage is that the body is much more expensive than the multi-functional OPT. The price is several times more expensive than the OPT working head. Most of the magneto-optical 360 instruments on the market are OPT instruments with a magneto-optical 360 working head. This type of DPL magneto-optical 360 instrument is actually just an OPT instrument replaced by a longer-life magneto-optical instrument. The 360 hair removal or skin rejuvenation work head has solidified the extension of the function. The relative price is more expensive than the ordinary OPT because of the difference in the replacement work head. It is not a complete magneto-optical 360, so the cost performance is very low! ! Purchasing is not recommended! ! The market price is generally around 13000-15000, and the price of the true magneto-optical 360 machine is generally around 16000-20000; it is suitable for high-end beauty salons and plastic surgery hospitals

The third type of 808 diode laser hair removal device.
The semiconductor laser hair removal device (full name is freezing point 808nm semiconductor laser hair removal device), its working principle is based on selective thermodynamics, the laser power supply is controlled by the microprocessor to provide an adjustable constant current for the laser module, so that the high power inside the laser module The laser diode converts electrical energy into light energy, and outputs a continuous laser with a wavelength of 808 nm. The effective penetration depth of the 808 nm wavelength can reach the target tissue (hair papilla). The appropriate pulse duration ensures that the target tissue produces enough thermal damage and the surrounding tissue is almost Unaffected so that the hair falls off and loses its ability to regenerate, achieving the purpose of permanent hair removal. In addition, the 808 freezing point semiconductor laser hair removal device adopts a sapphire epidermis cooling system, and the skin has a cool feeling during treatment, which is a real painless permanent hair removal device.
