The device is designed to work with the body's histamine response and prevent it from releasing histamines when pollen, dust and other allergens are detected. The medicine-free allergy solution is designed to be inserted into one nostril for a few seconds, then the other, so that [red and NIR light](https://www.trendhunter.com/trends/move-20) can reduce the body's inflammatory response. This can be repeated a few times daily or as symptoms continue to be bothersome. The device is set to be available later in 2021 and it sets itself apart as a drug-free, natural remedy for [seasonal allergy symptoms](https://www.trendhunter.com/trends/clorox-pure-allergen-neutralizer). Flō is clinically proven to help with everything from itchy eyes and sneezing to congestion without side effects.
