Worked fine for me, and makes sense to smother them.Ah! Ok! Should I use something other than Vaseline? Vaseline is the most suggested from everyone .
I used bag balm which is basically petroleum jelly(like Vaseline) but with a few other ingredients. Just know that, it can take weeks for new healthy scales to grow in. I would suggest coating legs once a week for 3 weeks. Then wait a couple months or so to see if things clear up or not.
