One thing that I discovered that works great for touchups is dried out solvent based glue.

If you have an old bottle of Ultrahold or other "clear" glue that has dried to the point where you can no longer use a brush, don't throw it away!. Take a toothpick and scoop out a tiny amount of the "dried" (it will still be pliable) glue and smear it on your skin underneath the lace where it is lifting. It should be dry enough that you don't even have to wait, you can press the lace down immediately into the thin layer of glue. Works like a charm!
