Wart Treatment
Looking for wart treatment in the Portland area? Knott Street Dermatology provides multiple forms of wart treatment for our patients.
Warts are caused by the human papilloma virus (HPV). The virus can be spread easily by human contact. Warts are typically located on the soles of the feet (plantar warts), the hands, and the genital region (condyloma). When they occur under a fingernail or toenail, they are called periungual warts.

There are several treatments: cryotherapy (applying liquid nitrogen with very cold temperatures), surgery, or electrocautery. Another way to treat warts is with an injection of a common type of yeast called Candida. A prepared version of the yeast is injected into the wart which causes the skin to turn red in a few days. It stimulates the immune system to become active in the treated area and, in turn, attack the virus causing the wart.
Another type of wart treatment involves Cantharidin. Diluted cantharidin is applied with a cotton swab directly to the warts or molluscum lesions and triggers the body’s immune system to fight the virus. Several treatments may be required to clear the skin.

Rachel Almada LE,CAE
Rachael graduated from the Aesthetics Institute in 2020 and recently acquired a Bachelor of Arts from Portland State University. Coming from a dermatology background, Rachael has a passion for skin health and sun protection. Her favorite part about being an Advanced Aesthetician is helping patients reach their skin goals and watching their confidence build because of it. She understands that everyone’s skin requires its own unique approach whether it’s a treatment plan or a skincare regimen.
When she is out of the office, Rachael enjoys traveling, trying new food, making art, and doing pretty much anything outdoors – especially if it includes her Doberman-mix pup, Rubio!
