Chloasma is a worry for middle-aged women. Increased life pressure, irregular work and rest schedule, and endocrine disorders caused by the arrival of perimenopause are factors that lead to the formation of chloasma. Due to the desire for beauty, melasma has undoubtedly become a concern for people. Women invest a lot of time, money and energy in beauty, but in vain. To remove chloasma on the face, you can’t just treat the symptoms, you have to solve the problem from the root. There are many treatments for melasma, both systemic and local, but there is no truly effective method. In recent years, with the continuous development of laser technology, its role in the treatment of melasma has attracted more and more attention from researchers. In the absence of any breakthrough in current treatment drugs, laser treatment for melasma has become a treatment method that is more popular among people. The working principle of laser treatment for melasma is mainly based on the following points: 1. Melanin has a wide absorption spectrum, so lasers of various wavelengths can act on melanin; Second, the thermal relaxation time of melanin particles is relatively short, about 50 to 500 nanoseconds; 3. The longer the wavelength, the stronger the laser's penetrating ability, but the worse its absorption by melanin. The basic principle of laser melanin removal is based on selective photothermolysis, that is, laser of a certain wavelength, after irradiating the skin of the affected area for a certain period of time, is selectively absorbed by the melanin particles in the affected area. After absorbing the light, the melanin particles rapidly expand and rupture to form small fragments. It is then phagocytosed by the body's phagocytes and excreted from the body without causing damage to normal tissues. Most of our female friends have restored their fair skin through laser freckle removal. Being old is not scary, being ugly is not scary. What is scary is being ugly and lazy. There are no ugly women, only lazy women. Chloasma is not as stubborn as imagined. Laser freckle removal has brought us unexpected results. However, laser freckle removal should be performed under the guidance of a professional physician to achieve the best results. Melasma can also be prevented: 1. Do not expose yourself to the sun for a long time. Wear a sun hat or hold an umbrella when going out. You can also apply titanium oxide cream to exposed parts when going out. 2. If you suspect that chloasma is caused by certain cosmetics, you should stop using them and observe whether the chloasma gets worse. It would be best to find the specific ingredient that causes the chloasma so that you can avoid using cosmetics containing this ingredient in the future. 3. In terms of diet, you should eat more fresh fruits and vegetables: such as celery, spinach, day lily, black fungus, lotus root, apples, pears, watermelon, etc. Eat less spicy and other irritating foods: alcohol, strong tea, coffee, onions, garlic, cinnamon, chili peppers, peppercorns, etc. 4. Keep a happy spirit and exercise more, but pay attention to the combination of work and rest. 5. Actively treat chronic liver and kidney diseases, correct menstrual disorders, regulate endocrine dysfunction, etc. Women can stop taking oral contraceptives and switch to other contraceptive methods, which may produce unexpected results. 6. If chloasma is caused by pregnancy and does not disappear on its own within six months after delivery, medical treatment is necessary. |
