Laser technology was born in the middle of the last century. It is a kind of light with the same nature emitted by particles at the high energy level when excited by a certain photon. Since its birth, laser has achieved extraordinary rapid development and is widely used in industry, medical treatment, commerce, scientific research, information, military and other fields. With the exploration and expansion of the global medical beauty market, the medical beauty field has also become an important application area of laser technology.
In recent years, with the continuous development of laser medical beauty technology, the application of laser in this field has gradually expanded. Laser cosmetology has become a new way of cosmetology in recent years, which can deal with a wide range of skin problems, including dealing with skin diseases, improving skin condition, and delaying skin aging. It can also provide targeted treatment for skin problems such as spots, acne, red blood, aging, tattoos, scars, and depilation, so as to whiten and soften the skin, improve the skin quality Anti aging and other effects.
The principle of laser cosmetology is very simple, which mainly uses the selective photothermal effect and optomechanical effect. The laser can remove or destroy the target tissue by generating high energy, focusing accurately, and having a certain penetration of monochromatic light, which acts on human tissue and generates high heat locally.
The selective absorption characteristics of light are mainly due to the different laser wavelengths, and the target tissues of the laser are also different. The components such as melanin particles, hemoglobin and water in the skin, as the target tissues often acted by the laser, have different absorption rates for different wavelengths of light. Therefore, as long as the laser with a specific wavelength is selected, targeted treatment can be given to different target tissues.
The photothermal effect and the photomechanical effect are the reactions generated after the laser acts on the target tissue. Whether thermal energy or mechanical energy is generated, it is a conversion of the energy form contained in the laser itself, and this energy conversion mainly occurs on the target tissue, has little impact on the surrounding normal skin, and ultimately produces the ideal therapeutic effect.
Laser cosmetology mainly relies on the above principles. For example, in the process of freckle removal, the selective absorption of light is used to select the appropriate wavelength of laser to lock melanin, and then the photothermal effect and optomechanical effect are used to explode the pigment particles in the skin, and then the pigment particles are discharged through the epidermis and metabolic system to achieve the effects of freckle removal, tattoo removal, and whitening.
In addition, in the process of laser beauty, the other effects of the above principles are also very obvious. For example, the photothermal effect can stimulate the regeneration of collagen in the skin, improve the skin condition, and delay aging; The photothermal effect of the laser can also directly peel off and vaporize the diseased tissue to achieve the effect of scar removal.
Laser beauty can not only deal with a variety of skin problems, but also has many advantages over other beauty methods.
First, the effect is remarkable. For different skin problems, laser has different solutions, which are more targeted. When laser cosmetology is used, the energy will directly act on the corresponding target tissue, and the root cause of the skin problem will be eliminated directly, so as to improve the skin problem and improve the skin state. In addition, laser cosmetology has a fast effect. Generally, the treatment effect can be seen immediately after the end of treatment and can be maintained for a long time, so the effect is very significant.
The second is high security. Compared with traditional beauty equipment, the energy of laser beauty works more on the target tissues without affecting the surrounding normal skin, so the impact of laser beauty on normal skin is minimal, which will not cause side effects and aggravate skin problems.
Finally, laser beauty is simple and fast. Different from the traditional beauty scheme, laser beauty is more simple and convenient. The treatment process of laser cosmetology does not require surgery, nor will it cause too much trauma. Therefore, after the end of laser cosmetology treatment, there is no need for too much post-operative repair, just pay attention to basic water and sunscreen, and reduce the irritation to the skin in diet and life.
In the actual treatment operation, many beauty lovers found that using laser medical cosmetology technology to improve skin problems often requires several treatments to achieve the best treatment effect, so they worried about dependence, and once the treatment stopped, some skin problems would recur.
As for whether the laser will cause dependence and relapse after treatment, beauty lovers need not worry too much.
