Using this foundation buffer brush is a breeze. First, dip the brush into your foundation or BB cream. Then, gently buff it onto your skin in circular motions for a smooth and even finish. Remember to use light pressure to avoid disturbing your makeup. When it comes to cleaning, wash the brush regularly with mild shampoo and warm water. Let it dry naturally in an upright position. This will keep the brush in good condition and ensure it lasts a long time. Also, don't forget to store it in a clean and dry place to prevent any damage.
