I don’t think I’m alone when I say I have several tubes of mascara. There’s volumizing, lengthening, thickening, curling, waterproof..and then there are all those small tubes of samples! Unopened mascara can last for a while (depends on formula). Opened mascara will typically last about 3 months before it starts flaking and drying up. I’m guilty of opening up new mascaras, taking a swipe, then not using for a bit. I tend to give my lashes a break from mascara for days at a time. This leads some formulas to start drying up before I even make a dent to the tube!
An easy trick to extend the shelf life of your mascara and keep it going on nice and smooth is to add a few drops of saline solution or eyedrops to the tube! Swish the drops around with the wand to blend it in. The solution will thin out thickened and clumping formula. Enjoy the extended shelf life!
