Alex Lee of our Washington bureau joins us live with what the experts advise. But some doctors warn that using makeup that's too old can be risky. The cosmetic industry says there's no mandatory standard for expiration dates on makeup, since each company has it's own formulation for it's products. But that leaves women guessing. I think it lasts just several months, particularly mascara.
Experts say the shelf life for eye makeup is more limited than other products.
Once mascara is opened and used, it should replaced after three months. And if it dries out, throw it away, or risk infection. And experts say liquid or cr me products, like foundations, are generally good for one to two years after they've been opened. Powder products, like blush, can last even longer. But there are signs you should look for when using any cosmetic.
