If any product requires refrigeration, we will note this on the product page and on the product label. While our products in general don't require refrigeration, we do recommend keeping them out of the hot sun (a hot car, in a purse left out in the hot sun) as this may melt the product, such as lip balms and salves. If this happens, place in refrigerator for about 15 minutes for it to harden back up; keep upright as some products can leak if melted.
