Perfect brush for buffing in concealer. I use this brush to cover skin discolorations and redness. It is best used to cover stubborn areas such as blemish marks, dark freckles, tattoos and age spots. It isn't the greatest for covering under-eye dark circles since less is more when using concealer under the eyes. Everywhere else is fair game, and you can avoid piling on the concealer because this brush really helps you achieve perfect coverage.
