I learned something new today. Some of you may know this but for those who don't, this is a treat :) When buying beauty or facial products, make it a point to label the date when you first opened it. Because most beauty products have Period After Opening expiry dates wherein you need to throw out produts after it exceeds the PAO date. Better throw them out that wasting hundreds of pesos/dollars on rectifying the damage brought about by expired products. TIP : Keep a masking tape in handy to label PAO dates so you won't miss it. For facial creams, when I know it is beyond expiry date and I still have a lot to it, I apply it to my heel. The heel is 10x thicker than the skin on your face and more often than not, cracked so apply them there to maximize usage. So the next time you see the symbol below, make sure to grab your masking tape and pen!
