With the advent of time, there is a wide range of medical aesthetic devices that can be used to adjust the skin of the aesthetician to an ideal state. Regardless of the company that produces these devices or the name of the treatment, it is important to remember that their therapeutic effects are basically based on the use of two types of energy: light and heat. There are different levels of safety for light energy and heat energy. The safest and most effective light energy used in medical cosmetology is “Intense Pulsed Light” (IntensePulsedLight), while the safest and most effective use of heat energy is “Fractional Laser” (FractionalLaser). The safest and most effective use of thermal energy is the “FractionalLaser”. It is because of this that many beauty seekers take it for granted that “Pulsed Light and Fractional Laser are very safe and can be used by anyone”. In fact, it is a misconception that pulsed light and fractional lasers are so red that they are abused and even used to replace maintenance. After all, they are medical devices that inevitably produce side effects. Are these factors considered together in the course of treatment, the skin of the candidate can withstand? Even if they are safe, there are certain requirements at the operation level, and only professionally trained doctors can use them, and if they are not used properly, they can cause some damage to the skin of the candidate. The use of light and heat energy to help regenerate and repair the dermis is the best expression of using medical treatment to supplement maintenance. The use of light and heat energy is a safe and effective way to further enhance the effectiveness of cosmetic care. Light and heat energy can break through the epidermis without incisions and help strengthen and repair the dermis, which is not easily reached by beauty care. Therefore, the medical value of photothermal energy is to help various tissues in the dermis to proliferate, regenerate and repair, and to assist in the advancement of cosmetic skincare from the doctor’s point of view. In this process, the most easy to enter the beauty seekers misunderstanding is – many unhealthy skin can also be phototherapy, which is not true. This is especially important to alert beauty seekers to treat their skin with scientific rigor. If one’s skin condition is unhealthy and has hidden problems of one kind or another, intense stimulation with light and heat energy is not recommended. What should candidates with poor skin conditions do? First of all, through the professional medical aesthetic treatment team to carry out a comprehensive assessment of the skin, after which a targeted treatment program can be proposed, when to build, when to destroy, when to supplement the repair, etc.. Therefore, different skin types and different skin problems have corresponding treatment and repair methods. If you go into a salon and the practitioner immediately recommends some kind of pulsed light or some kind of laser, that’s when you should be skeptical about their professionalism. Tips: Gentle use of photothermal energy to assist in beauty maintenance of the two “special” features: 1, can be added to the maintenance of energy to stimulate the dermis; 2, energy can be used to treat skin problems.
