DEAR DR. GOTT: A few weeks ago, you said putting nail hardener on skin tags helps to dry them and consequently they fall off. Would it be possible to do the same with seborrheic keratosis spots? I have many. Thank you for your consideration. I am an 80-year-old healthy female.

DEAR READER: Oddly enough, I just received a letter from a reader who indicated that she used it for that very purpose on an unsightly lesion. She applied it once daily, peeled it off after her daily shower, and then reapplied a new coat. The lesion was totally gone after several weeks. My guess is that the polish worked as a barrier, keeping the lesion dry and without vital oxygen for nourishment. She believed clear nail polish might have worked as well but did experience excellent results with the nail hardener.

Another option is to use hydrogen peroxide. Simply apply it daily with a cotton swab. Some sources recommend against using it undiluted, so try mixing with an equal amount of water.
