But that’s not all it does—using a grimy makeup tool can have long-term effects, ones you’ve likely never attributed to a brush or sponge before. Namely? Wrinkles. Yes, you read that right. Essentially, when your makeup brush or sponge dirties with old makeup, dead skin cells, and other particulate matter, those can trigger free radicals when introduced back to the skin. At this point, the excessive free radicals will start to trigger collagen and elastin destruction. Without these precious things, our skin starts to sag, lose volume, and wrinkle. So, yes, dirty makeup tools will trigger premature aging. So if you still go days or weeks or (gasp) months without washing your tools, let this serve as a reminder to you to do so. Because even if your makeup brushes aren’t causing you to breakout, they are doing something even more damaging in the long run.
