How to Keep Crest Whitestrips Fresh and Effective
To keep Crest Whitestrips fresh and effective, store them in a cool, dry place away from sunlight and heat. High temperatures and humidity can weaken the active ingredients, making the strips less effective. Room temperature is ideal, but if you want to extend their shelf life, storing them in the refrigerator is a great option. Just don’t freeze them—extreme cold can change their texture and reduce effectiveness. Always keep the strips sealed in their original packaging to prevent contamination and moisture damage. Avoid placing them in bathrooms or near radiators, where temperature changes are frequent. Proper storage helps maintain the whitening power, so you get the best results every time. And don’t forget to check the expiration date before use. Fresh strips mean a brighter, whiter smile.
