Melasma is a common skin problem. It causes dark patches on the face. These patches usually appear on the cheeks, forehead, nose, or upper lip. Many people wonder what causes melasma. Understanding the reasons can help you prevent it or manage it better.
What Is Melasma?
Before we talk about what causes melasma, let’s know what it is. Melasma is a skin condition. It makes dark, brown, or gray spots on the skin. It mostly affects women but can also happen to men. It is not harmful but can affect how you feel about your skin.
Doctors say melasma happens because of too much melanin in the skin. Melanin is the pigment that gives your skin its color. When melanin grows more in one place, it makes a dark patch. Now, let’s see what causes this increase in melanin.
Sunlight and UV Rays
The number one cause of melasma is sunlight. Ultraviolet (UV) rays from the sun can make melasma worse. When your skin gets too much sun, it makes more melanin to protect itself. This extra melanin causes dark patches.
If you spend a lot of time outside without sunscreen, you might get melasma or see it get darker. Even a short time in the sun can make melasma worse. That is why doctors say to use sunscreen every day.
Hormonal Changes
Hormones can play a big part in melasma. Many women get melasma when their hormone levels change. For example, during pregnancy, many women get melasma. This is why some people call it the “mask of pregnancy.”
Hormonal medicines, like birth control pills, can also cause melasma. These medicines change the balance of hormones in your body. This can make your skin produce more melanin.
Genetics and Family History
Melasma can also run in families. If your parents or brothers and sisters have melasma, you might get it too. Some people have skin that is more likely to make extra melanin. This is because of their genes.
Genes are passed down from parents to children. They decide many things about us, including our skin type. If your family has melasma, you should be careful about sun exposure and skin care.

Skin Type
People with darker skin tones get melasma more often. This is because darker skin has more melanin to start with. When something makes the skin produce even more melanin, dark patches can form easier.
But melasma can happen to all skin types. Fair skin can get it too, but it is less common. No matter what your skin color is, you should protect your skin from the sun.
Cosmetic Products
Some skin creams or cosmetic products can cause melasma. If a product irritates your skin, it can make melasma worse. The skin becomes sensitive and produces more melanin to heal itself.
Always check the ingredients of skin products. Avoid products with harsh chemicals or strong fragrances. If you notice dark spots after using a product, stop using it and see a doctor.

Other Causes of Melasma
- Stress: Stress can change your hormone levels. This might cause melasma.
- Thyroid problems: Some thyroid diseases can cause melasma.
- Medications: Certain medicines can make your skin sensitive to sun.
- Heat: Heat from the sun or other sources can worsen melasma.
How Does Melasma Develop?
Melasma happens when skin cells called melanocytes make too much pigment. This extra pigment stays on the skin surface. It shows as dark patches.
When you get more sun or have hormone changes, melanocytes get activated. They start producing more pigment. This can happen suddenly or slowly over time.
