It's important to wash your make-up brushes regularly. FYI, dirts and bacteria love to accommodate on your brushes. I recommend washing them every week.

How to Clean the make-up brushes?
Use make up cleanser such as Make Up For Life Brush Cleanser 160ml (Available in store) for a quick cleanse.

1. Spray and squirt the Make Up For Life  Brush Cleanser on your make up brushes.
2. Start by running your brushes under lukewarm water, rinsing out all of the residual makeup.
3. Gently swirl your brush tip on the palm of your hand with water.
4. Swipe the brush over a paper towel.
5. Lay your brushes on a cloth to dry and it's ready to use!
