20 minutes. Call your dermatologist’s office if your wound is still bleeding after 20 minutes.
If you have pain at the biopsy site, take acetaminophen or place an ice pack over the bandage to relieve swelling.
How to reduce scarring
Reduce scarring by protecting the biopsy site from the sun. Cover it with sun-protective clothing, apply a broad-spectrum, water-resistant sunscreen with an SPF of 30 or higher, and stay in the shade when possible.
You should continue your wound care until your stitches are removed. If you don’t have stitches, you should continue wound care until your skin is completely healed.
“If you have any signs of infection such as worsening pain, increased swelling, warmth or fever, contact your dermatologist,” Nijhawan says.
