Question

How do I know if my mascara bottle is empty?

Community Answer

You can try shaking it or turning it upside down to check. There is usually an expiration date on makeup.

Question

How can you tell if liquid lipstick tube is empty?

Community Answer

The best way to tell if the tube is empty to rest it on a flat surface, standing upright, and allow it to sit for a day or so. That will allow all of the remaining product to fall from the sides of the tube to the bottom, where the applicator is. When you pull it out, examine it to see how much lipstick is on the brush or applicator -- if there's hardly any product on it, the tube is likely empty or close to it.

Question

Can you put lipstick in the microwave to kill germs, then in a jar to reuse?

Community Answer

No, you should never microwave your cosmetics. It will not only kill germs, but also break down the chemistry and consistency of the makeup.

Question

Where can I find the expiry date information on the products?

Community Answer

Look on the back of the product––there is an open can symbol with a number inside. This will tell the months it can be used before it expires, e.g., 6 months after opening.

Question

My Dior lipstick doesn’t have batch code nor expiry date nor PAO. How can I know the expiry date?

Community Answer

Lipstick tends to last 2 years before expiring so if you can remember when you bought it, then you should know when it's no longer good to use.
