I have two circular scars from the stainless steel bolts that were in my shin. The upper one was a very uglier healer but it did heal smooth. I remember when the bolts were in I thought the bottom bolt would heal much prettier. Well beauty in the eye of the beholder and all that. The top/ugly scar healed smooth no problems. The bottom one healed smooth but with a hitch it’s concave. Lotion, sunscreen, water etc. gets trapped in it, for the past four years I’ve had this notch. This morning I noticed pain at the bolt location and to my surprise the scar is no longer concave! I’m looking forward to not having stuff stuck in it!!
