Facing all kinds of hair removal equipment on the market, and various hair removal principles, OPT, 808 semiconductor hair removal technology is currently the hottest hair removal technology. All of them advertise their effects very well, and the prices of similar instruments vary. The price of the most widely used OPT instrument ranges from thousands to tens of thousands. How to choose a suitable instrument?

Let’s talk about hair removal first! The principle of hair removal under popular science.

The hair of the human body can be divided into bristles and vellus (cuì), commonly known as bristles and vellus.

Hard hair: hard, darker in color, and medulla. Including long hair, such as hair, beard, armpit hair, chest hair, pubic hair, etc., generally greater than 25px in length; short hair, such as eyelashes, eyebrows, nose hair, ear hair, etc., generally less than 25px in length.

Vellus hair: thin, soft, lighter in color, without medulla, and relatively vellus hair or hairs, mainly distributed on the face, neck, limbs and trunk.

The hair cycle is generally divided into growth phase, anagen phase and stationary phase. After the resting period, the dead hair follicle falls off, another hair follicle is born, and a new growth cycle begins.

808 semiconductor laser hair removal and OPT hair removal are currently the two most advanced hair removal methods on the market. Both methods can achieve painless hair removal and permanent hair removal. Many customers ask what is the difference between these two hair removal methods?

Semiconductor laser hair removal device

Semiconductor laser hair removal device (full name freezing point 808nm semiconductor laser hair removal device), its working principle is based on selective thermodynamics, the laser power supply is controlled by a microprocessor to provide an adjustable constant current to 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 808nm. The effective penetration depth of the 808nm wavelength can reach the target tissue (hair papilla). The appropriate pulse duration ensures that the target tissue produces sufficient thermal damage and the surrounding tissues are almost It will not be affected, so that the hair will fall off and lose the ability to regenerate, achieving the purpose of permanent hair removal. In addition, the freezing point semiconductor laser hair removal device adopts the sapphire epidermal cooling system, and the skin feels cool during treatment. It is a true painless and permanent hair removal device.

OPT Hair Removal Device

OPT hair removal device (SHR+OPT dual beauty system) is an intelligent, non-exfoliative skin reconstruction system integrating epidermal cooling technology, perfect pulsed 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 photopyrolysis principle of patented strong pulse light source, and uses the absorption of specific wavelength of light by the melanocytes in the hair follicle to generate heat and selectively destroy the hair follicle. At the same time, the emitted heat can be conducted 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, thereby achieving the effect of removing the hair while avoiding damage to the surrounding tissues. Since the hair follicle can no longer be regenerated, the effect of permanent hair removal is achieved.

They are all air-cooled, water-cooled, semiconductor refrigeration, the treatment process feels comfortable, and can achieve the effect of permanent hair removal. It is worth noting that OPT uses dual wavelength cut-off technology: 640nm and 530nm to make the effect more precise. Among them, 640nm is used for hair removal; 530nm is mainly used for whitening and rejuvenating skin, removing spots and acne, etc.

In summary, the difference between semiconductor laser hair removal and OPT hair removal machine is that the former uses semiconductor laser: the wavelength is 808nm, which can only be used for hair removal treatment, and it is more professional. The latter uses intense pulsed light and radio frequency technology, dual-wavelength cut-off technology, in addition to hair removal, it can also be used for whole face rejuvenation, facial pigmented lesions (such as freckles, sunburns, age spots, and various types of pigmentation) and acne scars. Treatment etc., the effect is remarkable. In addition, OPT uses flat-top square wave technology to make the light uniform and the treatment more comfortable.
