How do I store Crest Whitestrips to maintain their effectiveness?
To keep your Crest Whitestrips effective, store them in a cool, dry place away from direct sunlight and heat. Excessive warmth can break down the hydrogen peroxide in the strips, reducing their whitening power. Avoid storing them in humid environments like bathrooms, where moisture can also affect the adhesive and active ingredients. Instead, consider keeping them in a drawer, cabinet, or even the refrigerator. Refrigeration is safe and can help extend shelf life, though it’s not required. Always make sure the packaging is sealed properly after opening to prevent exposure to air, which can degrade the product over time. Additionally, check the expiration date before use, as expired strips may be less effective or cause uneven results. Proper storage ensures you get the best whitening experience every time you use them.
