Some winter things belong on the Nice List…
but others? Your sinuses would definitely report them to the North Pole. 😭🎄

Dust from heaters, pet dander, moldy décor boxes, and dry indoor air can all stir up sneezes, pressure, and that mysterious winter stuffiness we always blame on the weather.

If your nose is acting Grinchy this season, let us help bring the comfort back.
