Ladies, would you know if you bought fake make-up

It's so much fake stuff out here. This is the industry that I am in LOVE with Make-Up!!!!

1. Never buy make-up from a authorized retailers only
2. Pay attention to the packaging
3. Check the bar code, serial number and manufacturing information
4. Check the shades of the products
5. Pay attention to the smell and consistency
6. Check brushes and sponges
7. Test makeup products before buying
