How to remove chloasma

　　As spring arrives and the sun gets stronger, many people’s faces quietly develop yellowish-brown patches—this is the “chloasma” that plagues many women. It is not painful or itchy, but it affects the appearance and even makes people look tired and aging. It is also called "liver spot" in medicine. It is mostly symmetrically distributed on the cheeks, like butterfly wings. So, how to effectively remove chloasma? In fact, the key lies in "cultivation both internally and externally".

Causes of chloasma

　　1. Endocrine disorders

　　When women are pregnant, breastfeeding, or taking birth control pills, the levels of estrogen and progesterone fluctuate, which can stimulate overactive melanocytes, leading to pigment deposition on the cheeks, forehead and other parts of the body. In addition, abnormal thyroid function and irregular menstruation may also induce or aggravate chloasma, which is the main reason why the proportion of female patients with chloasma is high.

　　2.Ultraviolet irradiation

　　Long-term exposure to the sun, ultraviolet rays will directly damage the skin barrier, activate melanocytes to produce a large amount of melanin, and destroy skin collagen fibers, leading to abnormal pigment metabolism. Even if you are exposed to the sun for a short period of time daily, long-term accumulation will make the spots darker and larger, becoming a key factor in the aggravation of chloasma.

　　3. Genetic factors

　　Chloasma has an obvious familial genetic tendency. If a direct relative has chloasma, the individual's risk of developing the disease will increase. Heredity determines the sensitivity of the skin to ultraviolet rays and hormonal changes. Melanocytes in this group of people are more susceptible to external stimulation and abnormal proliferation, forming symmetrical light brown patches.

　　4. Bad life and improper skin care

　　Staying up late for a long time and experiencing high mental stress will affect the body's metabolism and endocrine balance, and indirectly aggravate pigmentation.； Frequent use of skin care products containing heavy metals and hormones, or improper skin care practices such as excessive cleansing and acid application will damage the skin barrier, reduce skin resistance, and make chloasma more likely to appear or worsen.

How to remove chloasma

　　1. Sun protection is the first and most critical step

　　Ultraviolet light is the "switch" that activates melanocytes. Even on cloudy days, ultraviolet rays can penetrate the clouds and stimulate the skin to produce more melanin. Therefore, applying sunscreen with SPF30 or above and PA+++ every day, combined with physical shielding such as hats and masks, can prevent the aggravation of chloasma.

　　2. External use + internal medicine, two-pronged approach

　　External use: You can use ointments containing hydroquinone, retinoic acid (or retinoids), and vitamin C derivatives. These ingredients can inhibit melanin production and promote keratin metabolism. It needs to be used under the guidance of a doctor to avoid irritating the skin.

　　Oral administration: Large doses of vitamin C and vitamin E help to resist oxidation and reduce pigmentation. Some patients can also take tranexamic acid (tranexamic acid) as directed by their doctor, which has a certain effect on refractory chloasma.

　　3. Medical beauty treatment: laser and photorejuvenation

　　For darker pigmentation, simple skin care will be slow to show results. Technologies such as Q-switched laser, picosecond laser or photorejuvenation (IPL) are commonly used in clinical practice to accurately crush melanin particles and then metabolize them out of the body. However, you must choose a regular medical institution. Improper operation may cause anti-blackness or worsening of pigmentation.

　　4. Regulate endocrine and improve living habits

　　Traditional Chinese medicine believes that "liver qi stagnation" can easily cause chloasma. Staying up late for a long time and being emotionally depressed will affect hormone balance and make spots darker. suggestion:

　　Make sure to go to bed before 23:00 to allow the liver to detoxify normally；

　　Eat less spicy and greasy food and more fruits and vegetables rich in VC (such as tomatoes and citrus)；

　　You can take Xiaoyao Pills, Wuji Baifeng Pills and other Chinese patent medicines that regulate qi and blood under the guidance of a doctor.

　　Melasma does not form in a day, nor can it disappear overnight. The most effective method is: strict sun protection + rational use of medication + regular work and rest + medical intervention. Don’t trust “quick-acting freckle removal creams”. Many illegal products contain heavy metals or hormones, which can whiten your skin in the short term and ruin your face in the long term. Only by adhering to scientific care can your skin become truly translucent.
