Dermatend. It's a product I used to remove a "beauty mark" from my face. I followed the directions exactly and it worked. The packaging says it works on skin tags, too.
You can read reviews of Dermatend on amazon. One of the reviews gives a really detailed rundown of the process.

I didn't know skin tags were associated with aging. I thought it was strictly a skin rubbing on skin situation. Educational thread. Thanks.
