A face brush can refer to two different things: a brush used for cleansing and exfoliating the face, or a brush used for applying makeup. It is important to choose good quality brushes in both instances, and to replace them regularly to prevent bacteria buildup, which can lead to breakouts. A face brush used for applying makeup is somewhat more common, and there are a number of different face brushes used for different types of makeup. Quality makeup brushes are typically fairly expensive, but many people believe they are worth the investment.
The largest type of face brush used for applying makeup is that used for applying blush and foundation. This brush has a larger, rounded brush head, and is typically very soft. It allows for coverage over the entire face, such as when applying foundation, or when trying to achieve a natural look with blush. This type of face brush may also be used for blending makeup around the edges of the face, particularly the jawline, where one wants it to look most natural. A blush brush may also be separate, and slightly smaller than a foundation brush.
Brushes used for applying eye makeup are common as well. These brushes may be small and flat, for applying eyeshadow over the eyelid, or the may have a straight, angled edge for applying eyeliner or eyeshadow as eyeliner around the eyes. A lipstick brush usually has a small, narrow tip, which allows one to precisely apply the lipstick within the lips, without blending over the edges. In general, experts recommend purchasing high quality makeup brushes, because they last longer and give a more professional appearance to makeup. Wash these brushes regularly with gentle shampoo, and lay them flat to dry.
Of course, a face brush used for cleansing may be excellent for the face as well. Some of these are powered, and feature many tiny scrubbers that exfoliate the skin. Others are manual, and are simply rubbed gently over the face to remove makeup and grease from the day. A face brush used for cleansing will generally be able to get a deeper clean that just washing the face with the fingers, which can help to remove blackheads and prevent blemishes, as well as make the skin more able to accept moisturizer. Again, it is very important to keep this type of face brush clean, and to replace it if necessary.
