Drugstore Wart Removers: Salicylic Acid, Freeze Kits and Who Should Skip Them
SkinArticleSalicylic acid liquids, pads and at-home freezing kits promise to clear warts. A Cochrane review found salicylic acid beat placebo, but labels warn people with diabetes or poor circulation not to use it, and a new bump after 50 may not be a wart.
In this article
Warts on the hands or the soles of the feet are common, and the drugstore offers liquids, gels, medicated pads and at-home freezing kits. Here is what works and who should talk to a clinician first.
What the evidence shows
A Cochrane review of 85 trials with more than 8,800 people found:1
- Salicylic acid increased the chance of clearing warts compared with placebo, and seemed to work better on hands than feet.
- Freezing (cryotherapy) wasn’t clearly better than placebo when results were pooled, but more aggressive freezing worked better than gentle freezing, with more side effects.
- Salicylic acid and freezing worked about equally well, and together they worked better than salicylic acid alone.
- Duct tape didn’t beat placebo in two trials.
Many trials had a high risk of bias.1 The freezing studies mostly involved clinic treatment, not drugstore kits.
Who should skip drugstore wart removers
The salicylic acid label says don’t use it if you have diabetes or poor circulation.2 Don’t use it:2
- on the face, genitals or mucous membranes
- on moles, birthmarks or warts with hair growing from them
- on irritated, infected or reddened skin
If you have diabetes, foot problems need a clinician’s care rather than at-home acids or freezing.
Is it a wart?
New bumps after 50 aren’t always warts. Seborrheic keratoses, skin tags and skin cancers can look similar. Our guides to seborrheic keratosis removal and the risks of home mole removal explain why a check matters before you treat.
Using salicylic acid safely
- Soak and dry the area first, and apply to the wart only, avoiding surrounding skin.2
- Apply once or twice daily as directed, for up to 12 weeks.2
- Keep it away from flames and avoid breathing the vapors. Liquid removers are flammable.2
- Stop and ask a doctor if discomfort continues.2
- See a clinician if the wart spreads, bleeds or doesn’t clear. Our article on skin cryotherapy aftercare covers in-office freezing.
Try: “I have a rough bump on my hand that I think is a wart, and I have type 2 diabetes. Can you confirm what it is and suggest a safe treatment?”
Skin, Head to Toe includes a short-shelf planner and a 12-week SkinLog. Use them to photograph the spot weekly and track what you tried. See the book.
