Laser technology was initially used to treat various diseases, including hemangioma. With the development of laser technology, it is gradually applied to beauty rejuvenation, so color light rejuvenation and composite color light rejuvenation have been studied. In fact, from the development of laser technology to today, it is divided into many types of light, each of which has different functions. In this paper, the functions of various light in laser technology will be introduced in detail.
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. It has remarkable effect in skin care and health care treatment. It can improve the activity of cells, promote cell metabolism, and make the skin secrete a large amount of collagen and fibrous tissue to fill itself. Suitable for any skin, promote blood circulation, regenerate collagen, so as to make the skin smoother, improve skin dryness and scar treatment, and improve peeling hair and hair follicle appendicitis alopecia areata.
Blu ray: treatment of acne
The wavelength of 415nm has the effect of rapidly inhibiting inflammation. Propionibacterium mainly plays a role in the formation of acne. Blue light can effectively destroy this bacterium without damaging the skin tissue, minimize the formation of acne, and significantly reduce and heal acne in the inflammatory stage in a short time. Suitable for sensitive, oily and acne skin, reduce acne bacteria, so as to achieve the purpose of removing acne and acne, promote the synthesis of protein and bone collagen, activate skin, tighten loose skin and pregnant lines. It can contain or irradiate Yintang acupoints, play the calming effect, relax the body and expression, and have an effect on pain, sadness, blood stasis, soothing and calming.
Purple light: it is a dual frequency light of red light and green light. It combines the effects of the two kinds of light, especially in the treatment of acne and acne. Remove or inhibit the growth of hair in all parts of the body.
Yellow light: wavelength 590nm, combined with red light, has obvious effect on the relief and treatment of allergic skin diseases. Fade spots, 3 low waisted Korean women’s Taka pants, restrain the increase of melanin 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: smooth small wrinkles or lighten eye and face wrinkles and eliminate dark circles.
White light: remove the secondary skin inflammation such as red blood filaments and acne.
It can be seen from the above introduction that laser technology plays a different role in treatment. With the continuous development of science and technology and the innovation of means, laser beauty technology will develop in deeper and broader fields. With this trend, laser beauty technology will benefit people.
