Laser is a technology that is no stranger to those operating in the field of cosmetology and skin care. Over the past 15 years, the world cosmetology industry has witnessed continuous great achievements in the application of laser technology to aesthetics. Especially in Vietnam, although the start is quite late, but now a number of cosmetic centers have started to research and put in some of the latest generation of aesthetic laser equipment in the world.
Applications of lasers in cosmetology
In the field of aesthetics, laser technology has made important breakthroughs in cosmetic treatment, applied to perform many cosmetic treatment services, bringing satisfaction to many customers such as:
1. Laser treatment of vascular lesions
There are many different vascular lesions that can be treated with lasers. Laser treatment of vascular lesions became popular with the introduction of the argon laser in the 1970s.
Because of the location of blood vessels in the dermis, regulation, stabilization and cooling of the epidermis in the treatment of vascular lesions is important when using wavelengths that are also within absorption. of melanin. Longer wavelength vascular lasers can be operated without epidermal cooling. The selective photothermolysis effect plays an important role in the treatment of vascular lesions. The target oxyhemoglobin must absorb light, generate heat, and coagulate blood vessels without damaging surrounding tissue. Older vascular lasers often cause a high rate of hypopigmentation and scarring. Thus, the combination of photothermolysis and suitable pulse width will allow safe and effective treatment of vascular lesions without scarring.
Vascular lesions are common in people with skin accidents caused by using topical creams (mixing creams) containing corticosteroids, congenital hemangiomas in newborns, red birthmarks on the face that look less aesthetically pleasing, etc. addressed by laser safely and effectively.
2. Laser tattoo removal
Previously, once tattooed on the body, the tattoos would be permanent and difficult to remove without leaving scars on the skin. Hình xăm thẩm mỹ thường là sự pha trộn của nhiều loại mực khác nhau, khiến chúng vô cùng khó khăn để loại bỏ. Laser tattoo removal involves ablation of the entire area of skin that covers the tattoo, resulting in tattoo removal, but alteration of skin pigmentation, and even scarring. Devices for non-selective skin removal include CO2 lasers, argon lasers, and dermabrasion.
Nowadays, tattooing is gradually becoming a feature that many people love. Tattoo technology has also gradually changed significantly with the improvement of colors, including fluorescent and luminous ink. Currently, Laser can meet the needs of customers to remove unwanted tattoos relatively effectively without leaving bad scars. However, you also need to understand that laser tattoo removal is not an eraser, so many tattoos will not be completely removed no matter how many treatments are performed. In addition, there are some tattoo inks that actually become dark because of oxidation of the tattoo particles, which can lead to the formation of an ink color that cannot be removed. For professional tattoo removal, six to ten treatments may be required, spaced at least 6 weeks apart. For amateur tattoos is about three to five treatments.
3. Laser hair removal
Excess body hair is always a concern of many customers because they are directly related to aesthetic problems. Many people remove or remove hair by themselves by methods such as shaving, plucking, using hair removers, etc. However, none of the above methods can permanently remove hair and most of them can be used to remove hair. skin consequences such as scratches, folliculitis, atopic dermatitis, etc.
Today, permanent hair removal is one of the most commonly performed uncomplicated cosmetic treatments today. Almost every salon, spa and beauty clinic offers this service to their patients, using different equipment. In particular, Laser technology has been recognized by FDA (US Food & Drug Administration) as a safe and permanent hair removal technology. The energy from the laser will completely destroy the hair follicle and prevent hair from growing back. In addition to the completely destructive effect, the strength of this technology is that the energy from the laser does not damage the skin surface and does not cause harm to the client.
