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.
Here are some common cosmetics and the recommended shelf life for each after it has been opened for the first time. 1  Mascara: Toss your mascara after 3 months. 2  Eye pencils: Eye pencils can be kept up to 2 years. 3  Eye shadows: Keep your applicators clean and your liquid shadows should last 12 months. Powder shadows will keep 2 years. If youâve had an eye infection, youâll need to throw out all the eye make up and applicators you used from the time you developed symptoms.
