Stitches put in by the ER are normally non-dissolving nylon. I have been putting those in for 22 years. On face, they come out in 5 days, elsewhere 7-10 days. They are normally individual stitches and the tension is directly across the cut, but some do a running stitch, but the tension is on a diagonal and not as good. If individual, then each is a tiny loop with a knot outside. Typically, it is a nurse in an office who removes them, so you may find one at the conference, or an EMT. Usually, a good pair of fine scissors can cut the loop on one side of the knot and you then pull the knot. If you cut both sides, the loop is stuck in you. small layer of triple antibiotic ointment afterward. No proven benefit to Vit E or other stuff. Final appearance at 1 year. Keep it out of sun and/or use sunblock. I have heard of leg makeup to hide imperfections, so that would let your nice legs look their best.
Good luck!
