"Does having dark armpits mean having body odor (fox odor)?"

Dark Armpits May Not Necessarily Indicate Body Odor

Dark armpits do not necessarily signify body odor but could be caused by factors such as pigmentation, folliculitis, seborrheic keratosis, and more. It is recommended that patients promptly consult a physician, undergo relevant examinations, and receive treatment under medical guidance after determining the underlying cause. Here are a few possible explanations:

1. Pigmentation

Prolonged exposure to sunlight can stimulate excessive melanin production by melanocytes, leading to pigmentation in the armpit area, manifesting as dark armpits. Typically, no specific treatment is required; simply pay attention to sun protection.

2. Folliculitis

Caused primarily by bacterial infections, folliculitis presents as red papules centered around hair follicles, accompanied by itching and pain. When affecting the armpit area, it can contribute to darkening. Treatment options include applying mupirocin ointment or fusidic acid cream under medical supervision.

3. Seborrheic Keratosis

This condition may be genetic, triggered by UV radiation, or caused by viral infections. It manifests as flat papules on the skin, which can be light or dark brown. Therefore, it can also contribute to dark armpits. Treatment may involve topical retinoid creams or salicylic acid ointments as prescribed.

4. Other Causes

Diseases like vitiligo and pityriasis versicolor can also result in dark armpits. Vitiligo, a common acquired pigmentary skin disorder, characteristically involves the complete loss of skin and mucous membrane pigmentation, either locally or diffusely. When involving the armpits, it can lead to darkening. Treatment options include topical application of fluticasone propionate cream or mometasone furoate cream under medical guidance.

In daily life, maintain good personal hygiene by bathing regularly, changing clothes frequently, and avoiding spicy or irritating foods like chili peppers and garlic.
