How often should I clean my makeup sponges and brushes?
Often! Dirty brushes, powder puffs, and sponges are not good for skin. Puffs and sponges are more disposable (in most cases) and should be replaced. Puffs and sponges do not dry easily after cleansing and they are significantly cheaper than a quality set of cosmetic brushes. A dirty makeup brush is not only unhygienic but is quite likely to worsen or cause more breakouts, rashes, etc. Therefore, you should always clean your makeup brushes as they almost always have build ups of makeup, oil and bacteria. Once every 2-4 weeks should suffice for most people. There are many brush cleaners available. Two excellent brands worth mentioning are Masters Brush Cleaner & Preserver and “Pink Soap” Artist Brush Cleaner and Conditioner. They both clean and rinse out very well. They are available at any good art supply or cosmetic store. However, you can also simply use a good quality shampoo. Let brushes air dry. I do not recommend using a hair dryer to speed the process up. Heat damages brushes muc
