Makeup brushes do not only accumulate pigment liquids, powders & oils from products, they become laden with dust, dirt, sebum & dead skin cells. They are also a breeding ground for bacteria which is then transferred onto the skin to wreak havoc & compromise skin health. The importance of thorough, effective cleansing & disinfection of makeup brushes cannot be overstated. This Professional Brush Cleaner kills 99.9% of bacteria & viruses, so you can be confident your brushes are hygienically clean & won't transfer any harmful residue onto your skin. It strips brushes of product & dislodges even stubborn formulations like lipstick & concealer, whilst gently conditioning the bristles. It also has a 60 second ultra quick-drying formula. Alcohol is rapidly anti-microbial against bacteria, fungi & viruses meaning it can quickly eliminate these micro-organisms & cut through grime. It penetrates the cell wall & permeates the entire cell of the organism coagulating all proteins, meaning that microorganisms can no longer survive. The alcohol molecules evaporate rapidly so brushes are not only hygienically clean, they are quickly dry to the touch & ready to use.
