Why Do Melasma Spots Appear on the Cheeks?
Disease description:
After giving birth to my first child, I didn't have any skin issues on my face. However, after giving birth to my second child, I developed melasma. Why have brown patches appeared on my cheeks?

The causes of developing melasma on the cheeks are diverse, primarily including the following factors:
1. **Genetic factors**: Melasma has a certain hereditary tendency. If there is a family history of melasma, the risk of developing the condition may increase in offspring.
2. **Hormonal changes**: Imbalance in estrogen levels is a common cause of melasma in women. Fluctuations in estrogen levels, such as during pregnancy, while taking oral contraceptives, or during menstrual irregularities, may lead to pigment deposition.
3. **Ultraviolet radiation**: Prolonged exposure to sunlight can stimulate the skin to produce excessive melanin, making it prone to develop melasma, especially when proper sun protection measures are not taken.
4. **Endocrine disorders**: Abnormalities in the endocrine system may also contribute to the occurrence of melasma, such as chronic debilitating diseases or hyperthyroidism.
5. **Medication factors**: Certain medications, such as oral contraceptives and hormone-based drugs, may cause pigment deposition and lead to melasma.
If you have any concerns, please consult a relevant healthcare professional.
