I normally tell my patients to try not to touch the area for a couple of hours after, to prevent the risk of infection, and no make-up for 12 hours, or until the next day with dermal filler. Our hands are the perfect carrier for bacteria and lipstick/ lip moisturiser can contain microorganisms.
The following day is fine to apply makeup and lip balm. Remember that multiple incisions are normally made with the needle for lip fillers and the filler stays in the skin for a long period of time. It’s best to do everything we can to prevent a complication such as an infection from touching the area and applying make up.
