Since the rise of “lunch break beauty”, “steal time” to do a short beauty treatment, has been a common fast maintenance method for office workers. However, in the past, most of the beauty seekers are to do a facial maintenance, infrared light, once upon a time, but also popular to quickly play a laser, pulsed light, as if the light therapy has become a basic maintenance as if, everyone applies. This phenomenon worries many doctors at home and abroad, because they know very well that the light used in “medical aesthetics” is not the light saber in “Star Wars”, which everyone can play with; not to mention upgrading to the medical level and higher intensity of the laser! The beauty seeker has been brought into the realm of “medical aesthetics” without even realizing it. Lasers are also known as laser light. Because of the hype surrounding it, many people and even salon practitioners are under the mistaken impression that lasers are common and safe treatments that do not cause any harm. Now, it’s time to re-examine your aesthetic philosophy! Are the skin problems of the candidate solvable in the field of “lifestyle aesthetics”? If there are suitable treatments available, then the aesthetician should be the first choice. If the skin condition can only be improved with the help of “medical aesthetics”, then you can also consider it. Once you are in the “medical aesthetic” field, you need to choose carefully. Phototherapy is widely used in both the medical and cosmetic fields. Many media like to quote such an example, as early as the beginning of the 20th century, the United States National Aeronautics and Space Administration (NASA) on the use of LED light source on the astronauts’ muscles and bones for moderate irradiation, to promote wound healing. Because different wavelengths of light to different degrees to stimulate cell activity, speed up the metabolism. NASA’s medical experiments have proved that “in the wavelength of 650nm or so of red light irradiation, collagen eggs from the number of human body than the number of normal cellular differentiation produced by a full 5 times more”! No medium is needed to “penetrate the skin” and “generate heat”. The two properties of light make it a favorite of the medical and cosmetic communities. The medical profession has long proven that photothermal energy can promote blood circulation, accelerate lymphatic drainage, and enhance tissue repair. The beauty industry to use light thermal energy to achieve the effect of skin care has been practiced for many years, with the function of heat dissipation of small beauty instrument, in a variety of e-commerce platforms are very popular, which shows that the market by the degree of acceptance of the high. This kind of non-medical beauty equipment is even more indispensable for general beauty centers. The most common are infrared rays, far infrared rays, rock plate, steam, ionic activation of light heat energy, ultrasonic heat energy. We are surrounded by beauty and health care products full of light and heat energy, but the point is that these maintenance behaviors are non-invasive, non-exfoliative, all belong to the low-energy “light” and “heat” level, will not produce the phenomenon of anti-black. Beauty seekers need to establish the correct concept of light and heat: in the medical field, it can indeed promote tissue repair and regeneration; while the field of medical aesthetics, it is the destruction of problematic tissues and then construction. If you get it wrong, the consequences will be unimaginable. For example, if a candidate has a lot of acne marks on his face, what he needs is a dose of cosmetic repair, while the esthetician gives him the energy of a medical cosmetology instrument, which is inappropriate. It is also problematic to use the same photothermal energy in a thousand different ways to serve all candidates and all skin types. Photothermal energy is only a means to an end, and the proper use of medical devices and the maintenance of problematic skin must be taken into account in order to provide the best possible care for the patient. Even though there are many types of “lunch break beauty treatments” that are as convenient as buying clothes and cosmetics, it is advisable to choose a phototherapy program carefully. Thermal treatments performed at home must be non-invasive and non-exfoliating.
