With the continuous improvement of people’s living conditions, it has become the pursuit of the majority of beauty lovers to seek for fine, smooth, beautiful and healthy skin. However, due to various factors such as genetics, endocrine, metabolism, tumor, drugs and inflammation, pigmentation spots have crept onto people’s facial skin and become the biggest problem in the pursuit of beauty. What are the facial pigmentation spots? Melasma is the most common pigmentation spot on the face, which is a kind of flaky and relatively uniform brown spot on the face, mostly distributed in the cheek area, so it is commonly known as butterfly spot. Freckle is a kind of brown spot which is usually found on the face, and it starts to develop in early childhood, but usually people grow out slowly in adulthood, usually more in women, and this kind of spot also affects the beauty very much. This kind of spot is mostly found in middle-aged people, but it can also occur in the face of young people in their 30s. Sometimes age spots can also change in other parts of the body, and sometimes these spots can slowly rise above the surface of the skin, which is called age warts and is also very aesthetically displeasing. This pigmentation looks similar to freckles, but unlike freckles, a sunspotted face looks more like a “dirty” face and may be accompanied by other problems, such as sagging and dry skin. Freckle-like nevi appear as brown spot-like lesions very similar to freckles, but the distribution is very different from that of freckles, mostly in the form of limited flakes. Café au lait is a brown patchy pigmented lesion, mostly oval in shape, but of course it can also be irregular in shape. Nevus of Ota appears as a greenish-gray patch on the face. Cheek brownish-gray spots are a kind of punctate pigmented spots that occur in middle-aged women on both cheekbones, and may actually be a special type of nevus of Ota, so some people also refer to it as acquired nevus of Ota. Some of the lichen planus and sweat keratosis may also manifest as freckle-like damage. In addition various inflammatory skin diseases of the face (such as acne, etc.) can leave pigmented lesions (post-inflammatory hyperpigmentation) to varying degrees. Trauma or any skin inflammation can cause pigmentary changes in the skin. Some congenital skin diseases may also manifest themselves as various pigmented spots. How to treat facial pigmentation? There are various causes of pigmentation spots, and of course, the treatment methods are also different, and the efficacy also varies very much. Melasma: the best treatment is to avoid light as much as possible (sunscreen can be used appropriately) and to apply topical pigmentation drugs; acne (pimple) marks and pigmentation spots: it usually takes 1 year to fade slowly on its own, you can apply pigmentation drugs to accelerate the fading of pigmentation spots, photorejuvenation treatment and the latest E light technology can also help this kind of pigmentation spots to fade as soon as possible. Freckles: Q-switched multi-frequency Nd: YAG or Emerald laser treatment is not only highly effective but also does not leave any scars, the effect is very satisfactory. However, after the treatment, we still need to pay attention to sun protection, we can use sunscreen in summer, and we can use some spot removal drugs such as L-C. Sunlight tanning (photoaging): Photorejuvenation and the latest E light technology are ideal treatment options with very good efficacy, of course, Q-switched frequency Nd: YAG or emerald laser treatment also has good therapeutic effect. Of course L-vitamin C, and the application of retinoic acid creams have very good results on photoaging sunspots, but long-term use is necessary. Age spots and warts: laser treatment is a very reasonable option. Q-switched laser treatment is available, as well as high-energy CO2 pulsed laser treatment for damage that starts high in the skin. Post-inflammatory hyperpigmentation: medication options such as L-vitamin C, tretinoin or retinoic acid creams are preferable. Pigmented dermatitis from cosmetics: the best choice is medication, which can also be combined with photorejuvenation treatment. Freckle-like nevus, coffee spots, etc.: can be treated with Q-switched laser, but there is some recurrence, medication is usually ineffective, and surgical excision will leave significant scars. Nevus of Ota, Acquired Ota (brownish blue spots on cheek): Q-switched laser treatment is the most ideal treatment choice, which is not only highly effective, but also does not leave scars and has very high cosmetic value, but the course of treatment is usually long, usually requiring about 2 years of treatment. Flat warts, sweat hole keratosis: can apply high energy CO2 pulse laser treatment, or use Q-switched laser treatment, cryotherapy also has some therapeutic value. Therefore, before treating pigmentation spots, we should firstly make a clear diagnosis, and then choose a suitable treatment method (sometimes a comprehensive treatment is needed), and do not rush to the doctor. In addition, the treatment of pigmentation spots is an important part of medical cosmetology, and the efficacy of treatment must be guaranteed only by professional medical cosmetology specialists. What should I do if I have pigmentation spots on my face? First of all, you should go to the dermatology department of the hospital to see a doctor to get a clear diagnosis of pigmentation spots and find out what kind of problems your pigmentation spots are. Generally speaking, a clear diagnosis + a reasonable treatment plan + the necessary treatment time (course of treatment) will definitely have a very good treatment effect. How does the Q-switched frequency doubled Nd: YAG laser treat pigmentation? Q-switched laser is a high-tech modern laser technology developed in the 80s and 90s, which has a high degree of selectivity, which means that this laser only treats pigment particles, with no or only very little damage to normal skin. The surrounding tissues are also not burned, therefore, no scars are caused after the treatment. This laser can penetrate the normal skin on the lesion and reach the lesion. The pigment particles in the lesion are broken and destroyed by the powerful laser irradiation, and these broken pigments are then swallowed and eliminated by phagocytes in the body, thus the pigment spots are cured. However, the fading of the fragmented pigment is a very long biological process, so there is usually a certain interval of time between laser treatments, such as 1~6 months. Q-switched laser treatment for pigmentation spots, how many times will it cure my pigmentation spots? This is a question that doctors are most consulted, but it is a question that is almost impossible to answer because there are so many different kinds of pigmentation spots, and the nature of different pigmentation spots is different, and their treatment methods are also different, and of course the effect and the treatment course and the number of treatments are also very different. Is Q-switched laser treatment painful? At the time of treatment, you will only feel a slight pain on your skin, like a small ant bite, which is usually completely tolerable. For a full face treatment, the pain will be a little more intense, but completely tolerable. Think about how happy it is that the freckles that have been growing on your face, affecting your image and never giving you face are going to be cleared away, consider this feeling as your ritual to say goodbye to freckles. Will pigmentation spots recur after treatment? Different pigmentation spots are different in nature, and the treatment effect is different, so the possibility of recurrence will also be different. Some pigmentation spots will not recur after treatment, but some pigmentation spots have a certain possibility of recurrence after treatment.
