The good news is that checking your products takes only a few minutes\u2014and it can help protect the healthy, radiant skin you\u2019re working so hard to maintain.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Does the PAO Symbol Mean?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Many products include a small PAO (Period After Opening) symbol.  A jar icon with &#8220;6M&#8221; or &#8220;12M&#8221;, etc. That tells you how many months the product is considered safe and effective after opening. This &#8220;period after opening&#8221; marker helps you gauge when active ingredients may begin to degrade and when preservatives may no longer protect the formula, so following it can reduce the risk of irritation, and diminishing results. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Look for the small open-jar symbol on the packaging. Inside, you may see <strong>6M<\/strong>, <strong>12M<\/strong>, or <strong>24M<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is called the <strong>PAO symbol<\/strong>, or <strong>Period After Opening<\/strong>. It tells you how long a product is generally expected to remain suitable after you open it.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>6M:<\/strong>\u00a0Replace\u00a0approximately\u00a06\u00a0months\u00a0after\u00a0opening<\/li>\n\n\n\n<li><strong>12M:<\/strong>\u00a0Replace\u00a0approximately\u00a012\u00a0months\u00a0after\u00a0opening<\/li>\n\n\n\n<li><strong>24M:<\/strong>\u00a0Replace\u00a0approximately\u00a024\u00a0months\u00a0after\u00a0opening<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The countdown begins when you first open the product\u2014not when you purchase it. To avoid forgetting, write the opening date on the label or use a skincare-tracking note on your phone.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Following the PAO recommendation helps you avoid using products after their preservatives and active ingredients may no longer perform as intended.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">7 Signs Your Skincare Has Gone Bad<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Your product may be ready for the trash if you notice:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>A\u00a0strange\u00a0or\u00a0sour\u00a0smell<\/strong><br>A\u00a0noticeable\u00a0change\u00a0in\u00a0scent\u00a0can\u00a0signal\u00a0that\u00a0oils\u00a0or\u00a0other\u00a0ingredients\u00a0have\u00a0started\u00a0to\u00a0break\u00a0down.<\/li>\n\n\n\n<li><strong>A\u00a0change\u00a0in\u00a0color<\/strong><br>Darkening,\u00a0yellowing,\u00a0or\u00a0unusual\u00a0discoloration\u00a0may\u00a0indicate\u00a0oxidation\u00a0or\u00a0formula\u00a0degradation.<\/li>\n\n\n\n<li><strong>Separation\u00a0that\u00a0won\u2019t\u00a0mix\u00a0back\u00a0together<\/strong><br>A\u00a0little\u00a0separation\u00a0can\u00a0sometimes\u00a0be\u00a0normal,\u00a0but\u00a0permanent\u00a0separation,\u00a0watery\u00a0liquid,\u00a0or\u00a0visible\u00a0layers\u00a0can\u00a0be\u00a0a\u00a0warning\u00a0sign.<\/li>\n\n\n\n<li><strong>A\u00a0different\u00a0texture<\/strong><br>If\u00a0a\u00a0cream\u00a0becomes\u00a0gritty,\u00a0lumpy,\u00a0runny,\u00a0sticky,\u00a0or\u00a0unusually\u00a0thick,\u00a0it\u00a0may\u00a0no\u00a0longer\u00a0be\u00a0stable.<\/li>\n\n\n\n<li><strong>New\u00a0irritation\u00a0or\u00a0burning<\/strong><br>If\u00a0a\u00a0product\u00a0suddenly\u00a0stings,\u00a0burns,\u00a0itches,\u00a0or\u00a0causes\u00a0redness,\u00a0stop\u00a0using\u00a0it\u2014even\u00a0if\u00a0it\u00a0is\u00a0still\u00a0within\u00a0the\u00a0recommended\u00a0period.<\/li>\n\n\n\n<li><strong>Unexpected\u00a0breakouts<\/strong><br>A\u00a0product\u00a0that\u00a0once\u00a0worked\u00a0well\u00a0but\u00a0now\u00a0causes\u00a0bumps\u00a0or\u00a0congestion\u00a0may\u00a0have\u00a0become\u00a0contaminated\u00a0or\u00a0degraded.<\/li>\n\n\n\n<li><strong>Damaged\u00a0or\u00a0contaminated\u00a0packaging<\/strong><br>Cracked\u00a0containers,\u00a0broken\u00a0seals,\u00a0dirty\u00a0applicators,\u00a0or\u00a0products\u00a0exposed\u00a0to\u00a0water\u00a0can\u00a0increase\u00a0the\u00a0risk\u00a0of\u00a0contamination.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">When in doubt, it\u2019s safer to replace the product.

Look for the PAO symbol, smell and examine older formulas, and replace anything that seems questionable. Fresh, properly stored products give your skin the best chance to stay soft, hydrated, healthy-looking, and beautifully radiant.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>If a product has changed, caused irritation, or passed its recommended shelf life, let it go.
