Always remember to clean your makeup brushes after each use! It’s an extra step, but a necessary one. Not only does it keep your skin clear of blemishes, but it also prevents buildup and adds longevity to your brushes AND most importantly it keeps everything sanitary. I have a spray I purchased from Sephora and wipes from the drugstore that are specifically made for cleaning makeup brushes, but most of the time I just use simple soap and warm water. Allow them to air-dry over night and then you are set.
