How clean are your brushes?
Makeup brushes do not only accumulate pigment liquids, powders and oils from products, they become laden with dust, dirt, sebum, and dead skin cells. They are also a breeding ground for bacteria which is then transferred onto the skin to wreak havoc and compromise skin health.
The importance of thorough, effective cleansing and disinfection of makeup brushes cannot, therefore, be overstated.
