Causes of Melasma on the Face

For ladies who love beauty by nature, having spots on their faces not only affects their appearance, but also makes them feel inferior, thus losing their former optimism and self-confidence. Especially when the face is covered with annoying and annoying chloasma, it is quite troublesome to deal with and greatly affects the appearance of ladies, which makes many women hate it. So what is the cause of chloasma on the face?

In fact, there are many reasons for chloasma on the face. Not only women, but men may also get chloasma. There are many reasons for the formation of melasma, which may be caused by ultraviolet rays, endocrine disorders, or improper use of skin care products. Below we will introduce in detail the specific causes of chloasma on the face.

Melasma, also known as liver spots, is yellow-brown pigmentation on the face. Multi-symmetric butterfly distribution in the cheeks. It is more common in women, and high estrogen levels in the blood are the main cause. Its onset is related to pregnancy, long-term oral contraceptives, and menstrual disorders.

Cause: The cause is still unclear. It is more common in women, and high estrogen levels in the blood are the main cause. Its onset is related to pregnancy, long-term oral contraceptives, and menstrual disorders. It is also seen in patients with some female reproductive system diseases, tuberculosis, cancer, chronic ethanol poisoning, liver disease, etc. Sunlight can precipitate the disease. Male patients account for about 10%, and some studies believe that the incidence of the disease in men is related to genetics.

Clinical manifestations: The lesions are yellow-brown or dark brown patches, which are often symmetrically distributed on the cheeks and zygomatic regions, and may also affect the periorbital region, forehead, upper lip and nose, with generally distinct edges. No subjective symptoms or systemic discomfort. The depth of pigmentation is related to season, sun exposure, and endocrine factors. Mental stress, staying up late and fatigue can aggravate skin lesions.

Causes of Melasma on the Face

1. Ultraviolet radiation: Melanocytes in the skin will produce catalytic enzymes due to the stimulation of ultraviolet rays, which promotes the production of large amounts of melanin, causing the skin to darken. If melanin accumulates in a certain part of the skin, it will form spots or make the original spot problem worse. After being exposed to strong sunlight, fair-skinned women are more likely to develop sun spots and even dark spots; melasma will become more severe and spread; the number of freckles may increase and the color will deepen, so freckles are also called "summer spots".

2. Age increase: Many women find that the number of spots on their faces inexplicably increases after entering middle age. This is because age causes the metabolism to slow down, resulting in the extension of the metabolic cycle of melanocytes and the weakening of the skin's self-repair "preservation ability".

3. Endocrine disorders: The formation of pigmentation is related to the secretion of estrogen in the body. During a woman's menstrual cycle, the color of freckles tends to darken. During pregnancy or menopause, changes in hormone levels in women can also stimulate the secretion of melanin, causing more and more spots and darker colors.

4. Continuous excessive stress: When the human body feels stress, it will secrete adrenaline to make physiological preparations to deal with stress. If the body is threatened by stress for a long time, the balance of metabolism will be disrupted, the supply of nutrients needed by the skin will slow down, and the pigment stem cells will become very active.

5. Improper treatment methods: Chloasma is different from other pigmentation spots. Its causes are very complicated. Treatment should focus on internal adjustments. Laser, freezing, electrocautery and other methods should not be used, otherwise it may damage the skin texture, deepen the pigmentation, and expand the scope of the spots. Frequently exfoliating the skin's stratum corneum using some medicines or cosmetics containing exfoliants will destroy the skin's own resistance and greatly weaken the sun protection effect. At the same time, in order to restore its defense function, the skin will secrete more melanin, making melasma more serious and even turning it into dark brown spots.

Prevention: Since sun exposure is related to the onset or aggravation of the disease, you should pay attention to sun protection. When going out, you can apply creams containing sunscreen (such as 5% titanium dioxide cream, 5% salicylic acid benzoic acid ointment) or use a parasol. Pay attention to rest and avoid staying up late and causing mental stress.

After reading the above question about the causes of chloasma on the face, I believe everyone has some knowledge and understanding of how chloasma is formed. If you want to prevent chloasma on your skin, it is best to do a good job of daily sun protection, eliminate ultraviolet radiation, remember to use a parasol and apply sunscreen when going out, and also pay attention to rest and avoid staying up late.
