To minimize bacteria growth and keep your makeup brushes alive for longer, you should clean them about once a week. Instead of paying $32 for a makeup brush cleaning mat, use a paper plate and hot glue to get (basically) the same results.
DIY a makeup brush cleaning board. Inspired by secretlifeofabionerd youtuber. This board works really well. What you need it's a clip board and a hot glue gun. Small dots are for eye shadow / smaller brush heads; bigger dots are for face powder/ bigger brush heads; the wave lines are for cleaning out the soap. Hope it works for u guys too! :)
