What Was Done

Dr. Innes performed one of the following:

  • Shave biopsy — a thin scraping of skin removed from the surface using a blade. No sutures placed. Heals on its own over 1–2 weeks.
  • Punch biopsy — a small circular punch tool used to remove a deeper skin sample. One or two sutures are typically placed to close the wound.
🔬 About Your Results

If your biopsy was sent to a dermatopathology lab, results typically take 7–10 business days. Dr. Innes or a nurse will contact you when results are available. If you haven't heard back within 14 business days, please text 801-776-7129 to follow up. If your result requires additional treatment, we will discuss next steps with you at that time.

Shave Biopsy
No sutures · Heals by secondary intention · 1–2 weeks

Daily Care

  • Clean the site once or twice daily with soap and water
  • Pat dry gently
  • Apply a thin layer of Vaseline or Aquaphor over the site
  • A small bandage may be used if the site is prone to friction — otherwise ointment alone is fine
  • Continue until fully healed — usually 1–2 weeks

What to Expect

A small scab or crust will try to form over the site. Your goal is to apply ointment frequently enough that a dry, hard scab never forms. Moist healing is faster and produces a better cosmetic result. Keep it covered in Vaseline consistently — this is the most important thing you can do.

Punch Biopsy
Sutures placed · Follow-up for removal · Minimal scarring with proper care

Daily Care

  • You can leave the original bandage on for as long as it will stick — even 3–4 days is fine
  • Clean the site once or twice daily with soap and water
  • Pat dry gently
  • Apply a thin layer of Vaseline or Aquaphor over the sutures
  • Cover with a small bandage
  • Continue until sutures are removed

Suture Removal

If Dr. Innes told you sutures need to be removed, timing depends on location:

LocationSuture Removal
Face5–7 days
Trunk / arms7–10 days
Legs / feet7–14 days
Scalp7–14 days

If you are not already scheduled for suture removal, text 801-776-7129 to arrange it. Do not attempt to remove sutures yourself unless Dr. Innes has specifically told you that it's okay to do so.

What to Avoid

  • Picking at the scab or crust — let it fall away on its own
  • Submerging the site in pools, hot tubs, or lakes until healed
  • Applying makeup or skincare products directly over an unhealed biopsy site
  • Sun exposure on healing skin — can cause permanent hyperpigmentation; use SPF or cover with clothing
  • Vigorous exercise that causes sweating directly over the site for the first 2–3 days

Things You May Notice

✓ Normal — Expected
  • Mild redness, tenderness, and a small crust at the biopsy site
  • A small amount of bleeding or oozing on the day of the biopsy — apply firm pressure for 5–10 minutes
  • Mild bruising around the site
  • Slight itching as the wound heals
  • A faint pink mark that remains for several weeks before fading
! Contact Us If You Notice
  • Bleeding that does not stop with 15 minutes of firm pressure
  • Increasing redness, warmth, swelling, or pain after Day 3
  • Pus or foul-smelling discharge from the biopsy site
  • Fever over 100.4°F
  • A suture pulling through or coming out early
