Expired Cosmetics They say all things must come to an end, and this is especially true for your beauty products. Ingredients, application techniques, storage and packaging are all factors that affect the life of your products. Always store your cosmetics in a dry, cool area out of direct sunlight. Mascaras should be replaced at a maximum of three months. Those beautiful nail polishes can last up to two years. Most sunscreen products last one year and should have an expiration date printed on packaging. Moisturizers usually last one year once opened, along with serums. Since these are pretty general estimates be sure to pay attention to texture and smell. If the consistency or scent has changed, it is time to replace. On your next visit to Cos Bar ask your beauty expert about expiration. They can show you where to look and what to expect! Now go clean out that makeup bag it's 2016!
