What to do if you have chloasma on your face

The cause of melasma is unclear, and there are many factors involved in its occurrence, including genetic susceptibility, ultraviolet radiation, pregnancy, oral contraceptives, and certain cosmetic applications. The main reason is sun exposure, that is, ultraviolet radiation.

The generation and aggravation of melasma are closely related to light exposure, so the first step to prevent and treat melasma is to do a good job of sun protection. Physical sun protection mainly involves covering yourself, such as using a parasol, wearing a hat, and applying sunscreen. Sunscreen fits the skin better and has better preventive effects than the first two. The higher the sun protection factor (SPF), the longer the protection time and the better the sun protection effect. Use SPF15 to SPF20 indoors; if you are outdoors or traveling, you can use products with SPF20 or above; in areas with strong ultraviolet radiation such as plateaus and beaches, use sunscreen with SPF30 or above. It is best to apply it half an hour to an hour before being outdoors, and remember to reapply it at regular intervals.

Mild melasma can be treated with topical medications. The main drugs include hydroquinone, arbutin, retinoic acid, kojic acid, azelaic acid, vitamin C derivatives, etc. 2% to 4% hydroquinone preparations are the gold standard for depigmentation treatment but have adverse reactions including irritation or allergic contact dermatitis. Arbutin and deoxyarbutin are hydroquinone derivatives and are relatively less irritating. Retinoic acid may enhance the depigmenting effects of hydroquinone. Clinically, the combined use of hydroquinone and retinoic acid with topical glucocorticoids can achieve better therapeutic effects. In addition, my country also has traditional Chinese medicine ointments (such as Sibai Anti-Blemish Ointment) that can be used by patients every day for at least 2 months, and satisfactory results usually take 6 months.

Patients with severe melasma require systemic medication. Common drugs include vitamin C, glutathione, compound glycyrrhizin, tranexamic acid (toseramine), etc. Tranexamic acid is widely used in Japan to treat melasma, but excessive use can cause a rare adverse reaction, "thrombosis", so it is rarely used by domestic dermatologists. Some beauty salons use "whitening injections" for infusion and injection, and the ingredients mostly contain vitamin C, etc.; others use microneedles or no needles to inject drugs into the superficial layer of the dermis.

Based on the introduction of the above article, everyone should have a better understanding of the common sense of chloasma on the face. I hope it can bring more help to more female patients. Everyone must pay attention to taking care of their skin in life, eat a reasonable diet, pay more attention to rest and avoid excessive fatigue.
