The sun is warm, but it will do great harm to our skin. Too much exposure to the sun will not only make our skin black, but also form sunburn that is difficult to remove. How to remove sunburn? To solve this problem, a skin care expert at Mei Jia Hospital said, First of all, let's look at the causes of sunburn. The main causes of sunburn are as follows: 1. Ultraviolet rays: In the process of melanin production, the most direct influence comes from ultraviolet rays in sunlight. It can activate tyrosinase in melanocytes and react with tyrosinase in blood to produce a substance called dopa, which is then converted into melanin. 2. Toxin accumulation: Toxins in the skin can activate the activity of cells, and at the same time, they will undergo an oxidation reaction with tyrosinase to generate "dopa" to release melanin. The pollution, radiation and smog that we have to face in life will aggravate the oxidation process and make the skin color darker and more uneven. 3, cells are stimulated: pollution, sunlight and other external threats will cause inflammation of skin cells. In order to repair inflammation, skin cells will naturally react and secrete a tetraenoic acid, which will activate tyrosinase and promote the production of melanin to some extent. Laser freckle removal is the best way to remove sunburn. The principle of laser sunburn removal is that different types of lasers produce different colors of light, and a certain wavelength of laser is only absorbed by the pigment of the corresponding color. Therefore, a laser instrument is used to generate a high-intensity beam to make the pigment fade, so as to achieve the purpose of removing the color spots. Through the accumulation of tens of thousands of cases of clinical experience and years of research, Mei Jia has created a comprehensive freckle-removing therapy that combines internal adjustment with various laser and skin treatments assisted by traditional Chinese medicine, internal adjustment with external treatment, and integrated traditional Chinese and western medicine. The cure rate of simple chloasma is 98%, the effective cure rate of freckles, sunburn and pregnancy spots is 90%, and the cure rate of other comprehensive spots and moles is 85%. It is your first choice for freckle removal.
