What Causes Melasma?
While the exact cause of melasma is still unknown, there are several factors that are believed to contribute to its development. Some of the most common causes of melasma include:
Sun Exposure
One of the main causes of melasma is exposure to the sun's ultraviolet (UV) rays. This is because UV radiation increases the production of melanin, which is the pigment that gives colour to our skin. When the skin is exposed to too much sun, it can trigger the development of melasma.
Hormonal Changes
Another significant factor in the development of melasma is hormonal changes, particularly in women. Melasma is often referred to as the "mask of pregnancy" because it frequently occurs in pregnant women due to the hormonal fluctuations that occur during pregnancy. Hormonal birth control and hormone replacement therapy can also cause melasma.
Genetics
Some people are more susceptible to melasma due to their genetics. If you have a family history of melasma, you may be more likely to develop the condition and need melasma treatment.
Skin Irritation
Certain skincare products can irritate the skin and trigger melasma. Harsh chemicals, fragrances, and even some medications can cause skin irritation and lead to melasma.
Health Conditions
Certain health conditions, such as thyroid disease, can also contribute to melasma. Thyroid disorders can affect the hormones responsible for melanin production in the skin. Polycystic Ovary Syndrome (PCOS) can cause an increase in androgens, which stimulate the production of melanin in the skin, and can lead to melasma.
