The Southeast knows and grows peanuts. So when exciting news comes out, let’s just say I want to give you something to talk about. In today’s chatter, a skin patch that can decrease allergic reactions.

The findings were presented recently at the American Academy of Allergy, Asthma & Immunology (AAAAI) 2025 Annual Meeting and reported on via Medscape.com.

So what did they study and what did they find?

Researchers were looking at the VIASKIN Peanut Patch, which delivers focused amounts of peanut protein, measured in micrograms, through the skin. Context here, a microgram is on millionth of a gram.

The study addressed the longterm tolerance build after exposure to the patch, watching changes in children aged 4 to 11.

The findings:

The researchers found the percentage of children who could tolerate at least 300 μg peanut protein increased from 39.1% at the end of an initial 1-year trial to 52.9% after 36 months and 73.3% after 60 months. The proportion of participants who could tolerate at least 1000 μg peanut protein — a key threshold for desensitization — doubled.
