Dear Dr. Hibberd:
I have a serious problem with acidic sweat, and I can't wear colored clothes because the sweat bleaches them. What can I do?


Answer:
I'm sure you've been checked for underlying disorders associated with excessive sweating (such as thyroid, diabetes and other endocrine disorders, and infectious/inflammatory conditions), and I assume you are otherwise healthy. Try using a soap that is antibacterial as well as antiperspirant, such as Safeguard, or Mitchum antiperspirant products.
Aside from potent topical astringents, with or without prescription, you may be an excellent candidate to consider Botox. Although it's expensive, Botox injected into multiple sites to under both armpits will be very effective and will last four to six months.
