What Causes Darkening on the Inner Side of the Elbow?

Darkening on the inner side of the elbow may be caused by physiological reasons, eczema, acanthosis nigricans, and other factors. Physiological reasons do not require treatment, but if caused by eczema or acanthosis nigricans, drug therapy is recommended. Details are as follows:

1. Physiological Reasons: Long-term friction on the inner side of the elbow or poor personal hygiene can easily lead to darkening, but it will not cause discomfort. It is recommended to wear loose clothing, apply moisturizing lotion, and pay attention to local cleanliness and hygiene.

2. Eczema: If eczema develops on the inner side of the hand, the skin is subject to long-term inflammatory stimulation, which can easily lead to an increase in melanin in the skin, resulting in darkening on the inner side of the elbow. It is recommended to apply topical drugs such as Desonide Cream, Hydrocortisone Butyrate Cream, and Dexamethasone Cream to alleviate symptoms.

3. Acanthosis Nigricans: Acanthosis nigricans is mostly related to genetic factors. When the lesion involves the inner side of the elbow, there will be an increase in melanin locally, accompanied by metabolic disorders, leading to darkening. Drugs such as Tretinoin Cream, Isotretinoin Gel, and Cod Liver Oil Ointment can be applied to the inner side of the elbow to alleviate darkening.

Apart from the above common reasons, there are other possible diseases, such as psoriasis. It is recommended to receive timely treatment after a definitive diagnosis.
