Do you Clarisonic??? What a lot of people don’t realize, is that your clarisonic brush head and machine collect A LOT of makeup residue which could lead to a huge house of bacteria! Although you’re supposed to change your brush head out every 3 months, by keeping a weekly maintenance on your clarisonic, it could have it lasting just a little longer. Just take a toothbrush (the cheaper the better because they’re more stif) and twist off your clarisonic brush head. Your brush head then break down into 2 smaller pieces. Take some antibacterial soap or brush cleaner on your toothbrush to clean all of the nooks and crannies! You will be absolutely surprised to see how much makeup build up is actually back there and how easy it is to keep your machine clean! :) it took me about 2 minutes to clean mine!
