① solid-state laser; ② gas laser; ③ liquid laser; ④ Semiconductor laser.
The appearance of cosmetic laser provides a new technical treatment method for plastic surgery, and also solves many problems that cannot be solved by previous treatment methods. However, most cosmetic laser equipment only entered the medical industry in China in recent years because of its complicated technology and high price.
Laser realizes its function by interacting with tissues. According to what kind of energy the tissue converts the laser into, the laser is divided into;
① Photothermal effect: tissues convert the light energy of laser into heat energy, and different tissues have different absorption coefficients, so the laser with a specific wavelength can be absorbed by some specific tissues, which is the fundamental reason for choosing high laser for fine cutting, hemostasis and facial wrinkle removal.
(2) light burst effect: pulsed laser can produce shock wave with strong impact force, which makes tissues burst and smash, such as laser destroying pigment particles;
(3) Photochemical effect: tissue converts laser into chemical energy, resulting in chemical decomposition. Such as ArF excimer laser to correct corneal deformation;
④ Photodynamic effect: It is mainly used to treat tumors.
2, laser beauty according to the purpose can be divided into:
(1) Laser removes various pigments from facial skin, such as melanin (nevus, tattoo) and red pigment (hemangioma);
(2) Laser removal of skin defects, such as moles, warts, papules, vegetation and benign tumors;
(3) permanent removal of excess body hair by laser;
(4) removing facial wrinkles by laser;
(5) Using laser knife instead of scalpel to perform fine, minimally invasive and bloodless plastic surgery.
Pixel laser skin replacement
Skin photoaging is the manifestation of skin photodamage, which is mainly the cumulative result of long-term exposure to ultraviolet rays. It is characterized by wrinkles, slack skin, leathery skin and rough skin. When the skin is seriously damaged by light, it can be seen that the skin becomes thin, dry and rough, the skin pigment is abnormal, the capillaries dilate and the skin brittleness increases.
After treatment, the work and makeup will not be affected, and the skin will regain its vitality unconsciously, making it tender and elastic.
Composite Guang Cai freckle removing
Compound color light rejuvenation and freckle removal breaks through the traditional single color light technology and opens up a new technology of seven-color light beauty. Compound color light rejuvenation and freckle removal Seven bald heads are seven kinds of light source generators, including the latest five kinds of AFT color light, Q switch and long pulse laser, which act synergistically on skin target tissues, remove spots and bloodshot, stimulate collagen proliferation, enhance skin hydrophilicity, improve skin elasticity, and make freckle removal, whitening and skin rejuvenation one-stop. It only takes 15-20 minutes to remove freckles, spots, senile spots, sun spots, white spots, eyebrows, eyeliner and tattoos. Composite color light can rejuvenate skin and remove spots, and effectively solve your troubles. Let you quickly have radiant and charming young skin.
The function of various lights: red light: also known as bioactive light. The red light with the wavelength of 635nm has the characteristics of high purity, strong light source and uniform energy density, and has remarkable effects in skin care and health care treatment. It can improve cell activity, promote cell metabolism, and make the skin secrete a lot of collagen and fibrous tissue to fill itself. Suitable for any skin, promote blood circulation, regenerate collagen, make skin smoother, and improve the treatment of dry skin, desquamation, alopecia and scar. Blue light: treating acne
The wavelength of 4 15nm can rapidly inhibit inflammation. Propionibacterium is mainly at work in the process of acne formation. Blue light can effectively destroy this bacterium without damaging skin tissue, minimize the formation of acne, and obviously reduce and heal acne in a short time. Suitable for sensitive, oily and acne skin, reducing acne bacteria, thus achieving the purpose of repairing acne and acne, promoting the synthesis of protein and collagen, activating skin, tightening loose skin and stretch marks. It can accommodate or irradiate Tang Yin acupoints, play a calming role, relax the body and expression, and have therapeutic effects on pain, sadness, blood stasis, soothing and calming.
Purple light: It is a dual-frequency light of red light and green light, which combines the efficacy of the two lights, especially in the treatment of acne and acne. Remove or inhibit the growth of parallel hair in different parts of the body.
Yellow light: wavelength of 590nm, combined with red light, has obvious curative effect on relieving and treating allergic dermatosis. Fade spots, inhibit melanin increase, and remove spots.
Green light: Green light with a wavelength of 560nm, which is mainly used to control the secretion of oil. Improve sensitive skin and tighten coarse pores.
Lake Blue: Smoothes the tiny wrinkles in eyes and face or lightens wrinkles, and eliminates dark circles.
White light: remove secondary skin inflammation such as red blood silk and fanghua pox.
