Laser beauty principle
Our skin is composed of cells and stroma of different origins, with different optical properties (ability to absorb and reflect light) different skin structures can absorb or reflect different wavelengths of light, most light is able to penetrate the skin. This difference in the absorption and reflection of light by skin tissues opens up the possibility of using light for therapeutic purposes.
Laser technology began to be used in clinical practice in 1968, and research in cosmetic laser medicine began in the 1980s.
Aesthetic lasers act only on the cells or pigment particles to be destroyed to cause irreversible damage, while causing no or minimal damage to other tissue cells, so that the disease can be treated without leaving scars.
The effects of various types of light on the human body
Red light: wavelength 635nm, can improve the activity of cells and promote cell metabolism.
Blue light: with a wavelength of 415nm, it has the effect of quickly inhibiting inflammation, treating acne and revitalizing the skin.
Violet light: It is a dual-frequency light of red and green light, which combines the efficacy of both kinds of light and is especially effective in treating acne and getting rid of acne. Remove or press the growth of parallel hairs in various parts of the body.
Yellow light: wavelength 590nm, with the red light has obvious effect on the relief and treatment of allergic skin diseases. Lighten the spots, inhibit the melanin increase, and cut off the spots.
Green light: green light with wavelength of 560nm, mainly works to control the secretion of oil. Improves sensitive skin and tightens enlarged pores.
Lake blue: Smoothing small wrinkles or reducing eye wrinkles, eliminating dark circles.
White light: remove red blood, arthritis and other secondary inflammation of the flesh skin.
Classification of laser beauty
1. Laser hair removal
Laser hair removal is based on the principle of selective photothermal action, the target of selective destruction by laser is the rich melanin in the hair follicle, the melanin in the hair follicle absorbs the laser energy and the temperature rises sharply, resulting in local micro "blasting", leading to the destruction of the surrounding hair follicle tissue, thus achieving the effect of hair removal.
Advantages: hair removal is very thorough, fast, and does not harm the epidermis.
2. Laser Mole Removal
The principle of laser mole removal is that the huge energy burst of the laser is placed in the pigmented tissue in an instant, breaking up the pigment and breaking it down so that it can be swallowed by macrophages and then discharged out of the body with the lymphatic circulation system, thus achieving the purpose of removing the pigment.
3. Laser spot removal
The emitted laser light penetrates the damaged skin extremely smoothly, enters the damaged area, and treats the pigment in the damaged area. The pigment will change under the powerful laser light and then dissipate by itself, thus getting cured. Moreover, only the diseased cells absorb the specific laser light, while the normal skin tissue is not damaged, so laser pigmentation will not leave scars.
4. Laser wrinkle removal
The reasonably designed laser can absorb the energy released by the laser through melanin, hemoglobin and especially water in the skin, and produce photothermal effect to convert it into heat, thus activating various matrix cells such as fibroblasts in the dermis to produce new collagen, elastin and various intercellular matrix, thus filling the skin with folds due to collagen reduction, thickening the dermis and reducing wrinkles.
Advantages of laser cosmetic treatment
- Fast treatment, less damage to the skin
- High safety
- Less possibility of scarring
For the application of medical laser cosmetic products, Wavelength Photoelectric develops reflectors, filters, focusing mirrors, etc., which are applicable to the light guide arm of cosmetic instruments.
Wavelength photoelectric photorejuvenation filters have the advantages of high cutoff steepness, high transmittance and high background light density, and the characteristic cutoff wavelength will shift to the short wave direction when the incident angle changes (from 0 degrees to large angle rotation), which is completely different from the traditional optical glass method. This feature can be applied to fine-tune the system and get the wavelength you need.
