Photorejuvenation is a technique that has been developed in recent years as a cosmetic treatment. In general, photorejuvenation is actually a cosmetic treatment using Intensive Pulse Light (IPL) to eliminate/lighten various skin pigmentation spots, enhance skin elasticity, eliminate fine wrinkles, improve facial capillary dilation, improve facial pore size and skin roughness, and also improve yellowing skin color and other Skin problems. Treatment principle 1.Biostimulation Biostimulation is the photochemical reaction produced by the action of strong pulse light on the skin, which mainly has a chemical change in the internal molecular structure of collagen and elastic fibers in the dermis to restore elasticity; 2.Photothermolysis principle The pigmentation site allows its temperature to be higher than that of the surrounding skin after absorbing light, using their temperature difference to make the pigment break down and eliminate pigmentation, and will not damage normal tissue. Precautions after phototherapy Generally, no special skin care is required, but it is recommended to use skin care products under the guidance of a doctor, including stopping the use of all functional cosmetics (including various blemish creams, wrinkle creams, etc.), prohibiting skin grinding and the use of scrubs, etc. Since the cause of pigmentation and all kinds of photoaging is sun exposure, sun protection and sunscreen application is important, while skin moisturizer application is also needed. Who is suitable for photorejuvenation treatment? The first group of people: those who have spots on the face, whether sun spots or freckles, usually have a feeling of “dirty face” and cannot be covered up despite the use of powder. The second group of people: the face begins to appear sagging, fine wrinkles, aging skin changes. The third group of people: want to change the texture of the skin, hope that the skin elasticity is better, the skin is smoother, and improve the dull skin problems. The fourth group of people: facial skin roughness, enlarged pores, acne marks and facial capillary dilation. Usually the treatment effect is more obvious for the first three groups, and relatively less effective for the fourth group. Who are not suitable for photorejuvenation treatment? 1, photosensitive people and patients with recent application of photosensitive drugs, such people are sensitive to light and prone to skin damage after treatment; 2, pregnant women: because the treatment has varying degrees of pain, theoretically it cannot be completely ruled out that there may be potential effects on fetal development; 3, systemic use of retinoic acid (at least 2 months after cessation of use before treatment), such patients may have potential skin repair function of temporary weakening; 4, patients with melasma should be treated with caution, in most cases photorejuvenation does not solve the problem of melasma treatment, on the contrary, it sometimes makes the situation worse; 5, people with darker skin tone and prone to pigmentation should not use the method; 6, patients with unrealistic expectations of the treatment effect, photorejuvenation, although it has outstanding cosmetic ability, is only a very common It does not have the ability to change the nature of the skin, so patients should not have unrealistic expectations. What is the interval between photorejuvenation sessions? Photorejuvenation is generally divided into a treatment period, a rejuvenation period and a maintenance period. It is usually done five times, once every three weeks, and lasts for twenty minutes each time, and generally two to three times to see obvious results How to take care of the skin after photorejuvenation? 1, photorejuvenation treatment period of the skin is very sensitive, especially at this time to pay attention to sun protection, doctors recommend that try not to go out in the hottest and most sunny time.
