Photothermal therapy is widely used in the medical and cosmetic fields, and its core concept is mainly reflected in: first, the cosmetic “promotion of tissue repair and regeneration”; second, the medical “reconstruction of problematic tissue after destruction”. In short, it is regeneration and repair by stimulating the epidermis and dermis. Therefore, the combination of photothermal therapy for different skin types can achieve the purpose of skin regeneration and repair. However, it is important to note that not every skin type is subject to the same photothermal therapy. The exact combination of photothermal therapies used depends on the skin condition of the candidate. The skin’s oil and water distribution is an important reference factor. The following three situations can be used as a reference. 1, the skin with little water and oil secretion is not suitable for light and heat therapy The skin with little water and oil secretion means that the skin condition of the candidate is already very fragile. At this time, if you use light and heat to stimulate it, the skin is not able to withstand, not to mention repair. It is possible that once the light and heat treatment is applied, the skin will burn and turn black, which is a mistake. For this skin condition, we must use the “wipe” and “repair” treatment to repair the skin, gradually stimulate collagen growth, so that the maintenance products can be fully absorbed to restore the health of the skin. Only when the skin is restored to a healthy condition can we assess whether we need the assistance of light and heat. 2, water and oil less skin first use pulse light, then fractional laser water and oil less skin conditions, more likely to become dry skin and allergic muscle, resulting in poor skin immunity, that is, the dermis under the skin tissue damage, lymphatic circulation, blood circulation is not good. Therefore, we must first use the wide wavelength of pulsed light to stimulate the regeneration and repair of various tissues in the dermis and promote the improvement of f-tube lymphatic circulation, and at the same time supplement a large number of maintenance products rich in hydrating and water-locking ingredients, so that the collagen of the skin can be effectively increased. Only after the above treatment is done can the laser energy be used to stimulate the dermis underneath and strengthen the skin tissue layer by layer to achieve the goal of water-oil balance. In this process, the simultaneous use of zero or micro-thermal energy of the beauty micro-needle, with a minimally invasive way to supplement the beauty micro-sugar, can speed up the effect presented. 3. Fractional laser first for skin with less water and more oil, then pulsed light Because the acute phase of acne cannot be minimally invasive, oily skin can first use the fractional laser change technique with the probe applied away from the skin. The purpose is to allow the epidermis to receive uniform, appropriately intense thermal stimulation to deal with the troubling acute phase of acne first, so that the keratin and the different periods of acne across the face can be dried out simultaneously. In this way, the solidified keratin and pimples will become evenly falling skin flakes, and the face will enter a “synchronized pimple resting period”, looking much cleaner and brighter. Then, the wide wavelength of pulsed light is used to stimulate the repair of various tissues in the dermis layer, making the vascular and lymphatic circulation more smooth, and at the same time, a large amount of maintenance products rich in oil control and hydration ingredients are added to strengthen the conditioning of skin tissues and achieve a healthy water-oil balance. In this process, the simultaneous use of zero- or micro-thermal-energy microneedling and the minimally invasive supplementation of micronutrients can also make the results appear more quickly.
