The short answer: Clean your lip plumper applicator after every use with a gentle, alcohol-free cleanser or a specialized makeup brush cleaner, then let it air dry completely. For deeper sanitizing, use a 70% isopropyl alcohol wipe once a week. Avoid sharing applicators, and replace them every 3 to 6 months to prevent bacterial buildup and infections.
Your lip plumper applicator touches your lips, which are home to a natural mix of bacteria and yeast. When you apply product, you transfer some of those microbes onto the applicator, along with dead skin cells and any leftover product. If you don’t clean it, bacteria can multiply, especially in the warm, moist environment of the applicator tip. The next time you use it, you’re reintroducing those germs to your lips, which can lead to infections like cold sores, angular cheilitis, or even staph infections, especially if you have any small cuts or chapped lips.
Moreover, a dirty applicator can alter the texture and efficacy of your lip plumper. Old product can harden and harbor germs, reducing the formula’s freshness and potentially causing irritation. Regular cleaning keeps your applicator hygienic and your plumper working as intended.
Follow this simple routine after every use to keep your applicator in top shape:
Ideally, you should clean your applicator after every use, especially if you use your lip plumper daily. If you use it only occasionally, still clean it before and after each use to be safe. For the weekly deep sanitizing, set a reminder, perhaps every Sunday, to do the alcohol soak.
As for replacement, a good rule of thumb is every 3 to 6 months. Over time, the applicator’s material can degrade, making it harder to clean and more prone to harboring bacteria. Also, if you’ve had an infection like a cold sore, replace the applicator and the product to avoid reinfection.
If you’re using a lip plumper with a doe foot applicator (like a gloss), be extra diligent because these are more porous and can absorb product and bacteria. In that case, consider buying a backup applicator or using disposable applicators if you’re prone to infections.
Sometimes cleaning just isn’t enough. Replace your lip plumper applicator if you notice:
If you experience persistent breakouts or cold sores, it’s best to toss the product and start fresh. Also, if you’ve had an eye infection like conjunctivitis, replace everything that came near your face, including your lip plumper, to avoid cross-contamination.
Makeup wipes are not ideal because they often contain oils and moisturizers that can leave residue on the applicator, which can affect the formula next time. They’re okay for a quick wipe-off of excess product, but you should still wash with soap and water for a proper clean.
Hot water can be used, but avoid boiling water as it may warp or melt the plastic. Lukewarm water is best. If your applicator has a metal tip, hot water is fine, but still avoid boiling.
No, the dishwasher is too harsh and may cause damage. It’s also not hygienic to mix with dishes. Stick to hand washing.
