The spots on the face are a big problem for many female beauty seekers. After the spots grow on the face, they naturally think of using skincare products first, but the more disappointed they are with the things they bought, the longer they are, the more they seem to have no effect? Yes, skincare products are not effective because they cannot eliminate spots, but at most they can only prevent them from arising. There are many kinds of pigmentation, far from the word “spot”, and some of them are difficult problems for doctors. Therefore, it is necessary to classify the “spots” here so that they can be classified and treated in a more targeted manner. 1.Freckles Freckles are brown spots on the bridge of the nose and the sides of the nose, the size of a grain of rice. Generally, they have a genetic tendency and are often born, and are more obvious when they develop in adolescence. The color deepens in summer after sun exposure. The first thing to do for freckles is to protect them from the sun. You can use physical sunscreen, which has a certain covering effect and makes the color of freckles less obvious. If the color of freckles is lighter, the effect of using whitening products will be better, but it is difficult to get rid of them completely. At present, the best way to get rid of freckles is to use laser or photorejuvenation, and the effect is better for people with white skin. The area where laser has been done will not grow new spots, but still need strict sun protection, otherwise new freckles will be produced in other areas. 2.Chloasma Chloasma is commonly known as “butterfly spot”, “stretch mark” or “liver spot”. Generally, it is a yellowish spot on cheekbones, nose, forehead or around the mouth, and the edges are not clear. The appearance of chloasma is mostly related to endocrine, especially the level of estrogen and progesterone in women, therefore, irregular menstruation, pregnancy, taking birth control pills, poor liver function and chronic kidney disease are all prone to chloasma. In addition, sunlight and mental factors will also aggravate melasma. Because of the complex causes of melasma, it is difficult to treat melasma. Most of the chloasma appearing due to pregnancy can gradually fade away after delivery. If it does not fade for a long time, it needs to be treated. The treatment of melasma should be a combination of internal and external, sun protection is essential, and local use of whitening and spot-removing cosmetics can make the pigmentation fade. Oral intake of vitamin C, vitamin E and other anti-aging drugs will help. The treatment of melasma needs patience, at least two months to see the effect, do not be anxious. In addition, it should be noted that many lasers are not effective for melasma, and some of them will aggravate it, so be sure to consult your doctor before treatment. 3.Age spots have a great relationship with sunlight and are a manifestation of skin aging. In the early stage, they can be relatively small brown spots, the most exposed parts, flat at first, gradually become larger and thicker, and over time will raise the skin, the surface is rough, which is the most common elderly warts, the scientific name is seborrheic keratosis. Sometimes the age spots grow very large and dark, but they are still a benign rash and do not become malignant. There is no need to worry too much, you can see a dermatologist. Strict sun protection is the best way to prevent age spots, starting at a young age. People who work outdoors especially need to use broad-spectrum sunscreen all year round. If age spots have already appeared, topical whitening skin care products are not very effective, and laser can be done for flatter ones, and frozen for thicker ones. Tips: What is a physical sunscreen? Physical sunscreens are essentially very fine particles made of opaque substances that reflect or scatter UV rays so that they cannot enter the skin, providing broad-spectrum protection against UVA and UVB. The main ones are titanium dioxide, zinc oxide, talc, magnesium oxide, calcium carbonate and white clay. The advantage of physical sunscreens is that they are safe, not easily allergic, and more suitable for children and sensitive skin. The disadvantage is that it is thicker and easier to be white and unnatural when applied on the face.
