INTRODUCTION. Gastroesophageal reflux, also called acid reflux, occurs when the stomach contents back up (reflux) into the esophagus or mouth. Acid reflux is a normal process that occurs in healthy infants, children, and adults. Most episodes are brief and do not cause bothersome symptoms or problems.
How often to replace: 1  Mascara: every 3-6 months (which means youâll have to throw it away before itâs used upâ¦ the same goes for a lot of these products, probably) 2  Eye shadow: every 6 months. 3  Eyeliner (liquid): every 3-4 months. 4  Eyeliner (pencil): every 6-12 months.
Since expired cosmetics can cause skin irritation and eye infections, it's important to replace them before they go south. A new study from Stowaway Cosmetics and Poshly found that 89 percent of women hoard old makeup just in case. Plus, fewer than one in five of us trash mascara within the recommended three months (we're guilty, too). Unlike food, cosmetics aren't required to have an expiration date on their packaging. Instead, you'll have to keep track of when you opened them.
