After getting lip filler, it is generally recommended to wait at least 4 to 6 hours before wearing any lipstick, with a preference for creamy formulas over pigmented or long-wearing types. For safer healing, it is typically better to wait 24 hours before applying highly pigmented or long-lasting liquid lipsticks to reduce the risk of infection and irritation. During the first 24 hours, lips may be swollen and tender, so avoiding lipstick or other lip products helps the filler settle and prevents bacteria from entering the injection sites. After 24 hours, gentle, hydrating lipsticks with soothing ingredients are advisable, while harsh chemicals and strong fragrances should be avoided until lips are fully healed. Some practitioners suggest even waiting up to 1-2 weeks to fully reintroduce lipstick, depending on individual healing and the amount of filler used. Light lip balms or glosses may be used sooner but still with caution in the first day or two after treatment.
