We invest loads of money in buying new makeup products every time. Many times we avoid the date of expiring and use the same product twice. But apart from going into the bin, there are parts of products which we can reuse easily.
Here are some of the makeup hacks, take a look:

Expired mascara
If your mascara is now expired then apart from throwing everything into the bin you can wash the spoolie with some mild detergent and dip it under warm water. Use the brush to comb your eyebrows, or to de-clump your mascara.

Old eyeshadow
Find a new use for your eyeshadow colours by mixing it with clear nail polish and make new colours for your nails.

Old lipstick
Many times you get fed up with using the same lip colour. So to get a new lip tint scoop out the remaining colour and heat it over a candle flame gently in a spoon. Mix it with Vaseline and you can use this mixture as a lip balm for your dry skin. The heating also helps kill bacteria in the lipstick.

Skin toners
Skin toners after expiry can be used to clean glass and mirrors because they have alcohol in them.

Face Oils
Using the expire face oils can cause your skin to break out. What you can do is mix the face oil with sugar & voila and use it as a new body scrub, with a divine smell.
