Foundation (water-based) – It’s done after 1 year.
Foundation (oil-based) – Keep it only up to 18 months.
Lipgloss – Can last 18-24 months.
Lipstick – Will last 1-2 years. If it smells funny or does not glide on your lips smoothly, throw it away. Store your lipstick in the refrigerator to make it last longer. Lipstick can harbor a lot of bacteria and germs because of the way it is applied.
Lip Liner – Is old after 2 years.
Make-up Brushes – Wash at least every month to sustain the bristles’ life. I like to use brush cleaners like Sephora’s Daily Brush Cleaner after every use. Merely spritz this cleaner on your brushes and you’ve applied a quick anti-bacterial spray. For monthly or weekly cleanings, use Sephora’s Brush Shampoo, which easily removes make-up residue.
Make-up Sponges – Due to the material, make-up sponges should be tossed out after 1 month. Wash your sponges every week and air dry.
Mascara – 3 months tops! When using the mascara wand, don’t pump it up and down – you’ll let a lot of air in the mascara tube and germs and bacteria will want to live and populate there. Also, NEVER share your mascara with anyone. It’s easy to pass germs and contract a case of pink eye. Yuck!
Nail Polish – 1 year. Nail polish should never look like sludge or go on like cement.
Powder – 2 years. Sometimes, when powder goes bad, it smells funny and it’s difficult for you to apply it easily.
Always make a notation of the purchase date on your cosmetics. I use a Sharpie pen or stick a little paper with the purchase date on it with tape. If your make-up no longer performs the way it used to, or if it smells funny, throw it out immediately. Who knows what rancid little germs are creeping through your make-up?
