How to Remove Darkening Under the Arms Caused by Bromhidrosis

Axillary hyperpigmentation (darkening) associated with bromhidrosis (“fox odor”) can be addressed through timely cleansing, pharmacological interventions, and aesthetic medical treatments. Specific approaches are outlined below:

1. Timely Cleansing: Axillary hyperpigmentation may result from inadequate local hygiene. Maintaining good personal hygiene and consistent daily cleansing habits can effectively alleviate this symptom.

2. Pharmacological Intervention: Individuals seeking cosmetic improvement may take oral niacinamide tablets and vitamin C supplements. Topically, they may apply tranexamic acid–containing fragrances or a compounded formulation combining hydroquinone cream with urea and vitamin E emulsion. These agents contain both skin-lightening and deodorizing components, which help significantly reduce axillary hyperpigmentation associated with bromhidrosis.

3. Aesthetic Medical Treatments: Patients may consult qualified dermatologists at reputable tertiary hospitals for aesthetic procedures such as chemical peels, intense pulsed light (IPL) photorejuvenation, picosecond laser therapy, or ultra-picosecond laser therapy. These light- and energy-based modalities disrupt melanin granules, suppress melanogenesis, and promote melanin clearance—thereby achieving skin brightening. Alternatively, mesotherapy (e.g., “hydrafacial” or “glow” injections) incorporating skin-brightening agents may be considered.

It is recommended to maintain regular skin care and wear breathable, 100% cotton clothing. If symptoms are severe, professional evaluation and treatment under physician supervision are advised.
