[The doctor answers].Melasma on is a common problem, especially as you age, when they are more likely to appear on the face. Some people may have these spots all over their face, while others can maintain clean skin. This phenomenon has sparked curiosity, and many people wonder why this discrepancy is occurring. This article will delve into the causes of melasma and why some people are susceptible to it, while others keep their skin clean and healthy.
1. Definition and classification of melasma
Melasma, also known as age spots, dark spots, or brown spots, is a pigmentation problem. They usually appear as brown or black spots that appear on the face, neck, back of hands, and other areas exposed to the sun. Melasma is classified into the following types:
Exposure to sunspots: These spots are formed due to long-term exposure to ultraviolet sunlight, resulting in hyperpigmentation. They usually appear on the face, chest, and arms.
Freckles: Freckles are a hereditary pigmented spot that usually appears at a young age. They are small, light brown spots that are mostly located on the face.
Melanocytic spots: These spots are usually larger, darker in color and appear on the face, neck, and arms. They are pigmentation due to sun exposure or other factors.
Mixed pigmented spots: This type of pigmented spots can be caused by a variety of reasons and is usually a combination of sun-exposed spots and melanomalous spots.
2. Causes of melasma
The causes of melasma are complex and diverse, mainly including the following factors:
Ultraviolet exposure: Ultraviolet B (UVB) and ultraviolet A (UVA) radiation stimulates the production of melanin, resulting in pigmentation. Long-term exposure to the sun, especially without sun protection, increases the risk of melasma.
Genetic factors: Genetic factors play an important role in the formation of melasma. If there is a case of melasma in the family, then the risk of developing melasma in the individual is also increased.
Hormonal changes: Hormonal changes can affect pigmentation. Melasma is more likely to occur in pregnant women, women with polycystic ovary syndrome (PCOS), or those who take certain birth control pills.
Age: As we age, our metabolism slows down, making pigmentation more likely to appear.
Inflammation and irritation: Some problems, such as inflammation, wounds, or chemical irritation, may cause hyperpigmentation.
Pigmentation**: Some people** are inherently more prone to pigmentation, making them more susceptible to melasma.
3. Why are some people prone to melasma?
To understand why some people are prone to melasma while others maintain clean skin, we need to consider individual differences and the influence of a variety of factors.
Type: Different types react differently to UV rays and pigmentation. Some people** contain more melanin and are therefore more prone to pigmentation. In addition, sensitivity** may be more susceptible to external irritants and damage, which can trigger hyperpigmentation.
Heredity: Genetic factors play a key role in the formation of melasma. If there are cases of melasma in the family, then the genetic background of the individual may increase the risk of developing the disease.
Lifestyle: An individual's lifestyle habits, especially sun exposure and protective** habits, will directly affect whether they are prone to melasma. Precautions such as using sunscreen, avoiding sun exposure, and wearing hats and sunglasses can reduce the risk of hyperpigmentation.
Hormone levels: Hormonal changes may trigger hyperpigmentation. For example, a woman's hormone levels change during pregnancy, increasing the likelihood of developing melasma.
Age: As we age, our metabolism slows down, making pigmentation more likely to appear. This is one of the reasons why melasma is more common in older people.
Healthy Winter Plan Melasma is a common** problem, and a variety of factors can contribute to its formation, including UV exposure, genetics, hormones, age, and lifestyle.
