We’ve all done it but now that we know the facts let’s think about this. I’m talking about using a make-up product that’s way past its expiration date. After all, you shelled out major dough for that mascara, so why would you want to toss it once the date on the tube has come and gone? I totally get it. BUT…. expiration dates serve a bigger purpose than merely getting you to buy another product. Thatâs because old make-up not only works less efficiently, it can do major damage to your skin. 
So what happens when you use expired make-up? Your expired make-up will start to harbor bacteria. When it comes to your skin, this can mean irritation and bumps that look like acne. And when it comes to your eyes, this bacteria buildup can actually cause infections and pink eye. As for lipstick, using an expired one can cause swelling. So as a general rule, you should replace your mascara every three months, eyeliner and eye shadow every six to 12 months, and lipstick every one and a half years. Meanwhile, the average expiration date for foundation, powder, and other facial makeup is 12 months.
As for cleansers, treatment products for fine lines, the consistency of the product will change. The efficiency of active ingredients also becomes compromised over time. So stay on top of your products whether it be from me or another brand. If you ordered from me, every product sold has an expiration date on the product. So take care of your skin. It’s the only one you get.
