(terse reply over bandit wireless from my sister's kitchen...)

After steri-strips fall off? more steri strips.

The ideal cut: right angle to skin so, with luck, both edges retain good capillary blood flow. At an angle, one side of cut may more likely have impaired blood flow to dermis. Less blood flow == less enthusiastic participation in healing -- may just refuse to join in. Spuerglue nice to keep edges in place, but can't make skin play ball.

IANAPS.
