Hello! Thank you for reaching out with your questions regarding body odor, blisters, and eczema. These are common skin concerns that many people experience, and I’m here to help clarify and provide some guidance.

1. Body Odor (Bromhidrosis): The mild acidic smell you notice when you raise your arms may indeed be related to body odor, commonly known as bromhidrosis. This condition can be influenced by various factors, including genetics, diet, and hygiene practices. The association between wet earwax (cerumen) and body odor is noted in some studies, as individuals with wet earwax tend to have a higher concentration of certain bacteria that can contribute to odor. If the odor is not bothersome and does not affect your daily life, treatment may not be necessary. However, if it becomes more pronounced or bothersome, you might consider using antiperspirants or consulting a dermatologist for further options.

2. Small Blisters on Fingers: The small, transparent blisters that appear on your fingers during the summer and release fluid when squeezed are likely a form of dyshidrotic eczema, also known as pompholyx. This condition is characterized by small, itchy blisters on the palms of the hands and soles of the feet, often triggered by heat, humidity, or stress. The absence of redness or larger blisters does not rule out this diagnosis. It’s essential to keep the affected area dry and avoid irritants. Over-the-counter topical corticosteroids may help reduce inflammation and itching. If the condition persists or worsens, a dermatologist can provide more targeted treatments.

3. Eczema and Lichenification: The rough, lichenified skin you describe on the inner side of your knees is a common manifestation of chronic eczema or atopic dermatitis. This condition can lead to thickened, leathery skin due to prolonged scratching or irritation. While it may not completely resolve, it can be managed effectively with proper skincare. Regularly applying emollients or moisturizers can help maintain skin hydration and reduce the urge to scratch. Topical corticosteroids may also be prescribed by your doctor to alleviate inflammation during flare-ups.

Regarding your scalp, it is generally not recommended to apply regular body lotions to the scalp, as they can lead to buildup and exacerbate oiliness. Instead, consider using a specialized scalp moisturizer or treatment designed for oily or flaky scalps. If you experience persistent dandruff or scalp issues, a medicated shampoo containing ingredients like ketoconazole, salicylic acid, or zinc pyrithione may be beneficial.

In summary, while these skin concerns can be bothersome, there are effective management strategies available. Maintaining good hygiene, using appropriate skincare products, and consulting with a dermatologist when necessary can significantly improve your skin health. If you have further questions or concerns, don’t hesitate to reach out for more personalized advice. Take care!
