Brushes and sponges

Oils and bacteria can become trapped in brushes and sponges, which is bad for your makeup tools and your skin. Wash natural-bristled brushes once a month and synthetic brushes three to four times a month, using a brush cleanser, mild soap or baby shampoo. After washing, lay brushes flat to dry so the bristles don’t break or lose their shape. If you properly care for your brushes, they can last for years.

If you use cosmetic sponges to apply makeup, wash them weekly and toss them after a month or when the sponge begins to tear.
