2. Endocrine Disorders

This generally refers to imbalances in various hormones due to disrupted feedback regulation mechanisms, leading to a series of metabolic abnormalities. Symptoms may include pigmentation, excessive hair growth, and dry skin. Medications such as Zhenyuan tablets or methylprednisolone tablets may be used under medical supervision.

3. Pityriasis Versicolor

This condition may be related to fungal infections, environmental factors, and poor lifestyle habits.

Topical treatments such as miconazole nitrate cream or bifonazole cream can be applied under a doctor’s guidance.

In addition to the above causes, similar symptoms may also result from seborrheic keratosis, acanthosis nigricans, or tinea corporis. It is recommended to wear loose, comfortable clothing, preferably made of cotton.
