Toss after: Two years. These hearty exfoliants are made of virtually indestructible materials, but an open tub will still become a breeding ground for bacteria over time.
Toss after: Four to six months. Benzoyl peroxide and salicylic acid, two of the most common pimple fighters, decay quickly. Keep them in the refrigerator for maximum potency.
Toss after: One to two years—it varies, so check the expiration date on your tube. Keep sunscreen in a cooler when at the beach and trash any tube that’s been left sitting in a hot car.
Toss after: One year. Though a plain moisturizer without anti-aging ingredients will last well past this mark, you can contaminate it by dipping repeatedly into the jar. GET THE REST HERE!
