”One white covers all the ugly”, but the chloasma emerges on the fair face, making the skin dull and colorless, which makes the beauty how distressed. Melasma, also known as liver spot, butterfly spot and stretch mark. It is a common acquired hyperpigmentation skin disease that occurs on the sun-exposed parts of the face and aggravates after sun exposure. It is a kind of flocculent diffuse pigmentation with unclear boundaries, sometimes it can be distributed in a network, often appearing around the cheekbones, forehead and mouth and lips, usually symmetrically distributed on the left and right. In addition to the tendency to grow chloasma during pregnancy, sun exposure, endocrine disorders caused by irregular work and rest, and certain chronic diseases may also contribute to the formation of chloasma or aggravate the original chloasma. If melasma is not treated, it is difficult to disappear by itself. Moreover, since melasma pigment is more active and there are more causes of melasma, it will take more time and patience to treat than other pigmentation. So, how to say goodbye to melasma and refuse to be a “yellow face”? 1.Balanced diet, reasonable nutrition structure, avoid eating some spicy and stimulating food, and pay attention to eating more vitamin-rich food in daily life, such as tomatoes, cucumbers, carrots, barley, milk, beans, citrus, strawberries, fresh peaches, hawthorn, etc. 2, work and rest should be regular, do not stay up late, do not smoke, do not drink, keep the body and mind happy. 3, pay attention to sun protection, especially when the UV rays are strong, go out to do sun protection measures. If you have been exposed to the sun for a long time when the UV rays are strong, in order to prevent your skin from becoming dry and taut, or even dry and cracked, you should pay attention to replenishing moisture, using moisturizing ingredients in the moisturizer on the face, and then gently press the face with the palm of your hand to promote the absorption of moisture into the skin, so that, after several repetitions, the skin can regain its original moisturizing ability and maintain the skin barrier. 4.When necessary, you can use some topical hydroquinone cream or retinoic acid cream under the guidance of a doctor, and at the same time, you can use some Chinese herbal medicine under the guidance of an herbalist to soothe the liver, tonify the kidneys, invigorate the blood and benefit the qi. 5.Supplemented with laser treatment: As melasma is pathophysiologically manifested by the special nature of abnormal active melanocytes, selective light blasting is only performed on melanin particles within or between melanocytes in terms of energy selection, and the function of melanocytes is inactivated or inhibited through low-energy, multiple light blasting effects. This can not only improve the epidermal pigmentation, but also correct the skin vascular abnormalities and inflammation, which is not a good way to treat melasma. In a word, the cause of melasma is more complicated and the treatment process is longer. Generally, two or more ways should be applied in combination to reduce melasma to the maximum.
