From the Research
It is crucial to avoid excessive smiling or facial movements for at least 24 hours after lip injections to prevent filler migration and ensure optimal results. Studies suggest that facial movements, including smiling, can potentially cause the filler to migrate from its intended placement, affecting the final results 1. During the initial healing period, the filler material is still settling into position, and excessive movement may disrupt this process. Additionally, smiling stretches the lip tissue, which could exacerbate swelling and bruising that commonly occur after the procedure.
Some key points to consider after lip injections include:
- Avoiding touching or massaging the lips unless specifically instructed by the provider, as this can similarly displace the filler
- Resuming normal facial expressions gradually after the initial 24-hour period, with some practitioners recommending continued moderation for up to a week in cases of extensive injections
- Understanding that hyaluronic acid fillers need time to integrate with surrounding tissues and bind with water molecules to achieve their full volumizing effect, as discussed in various studies 2, 3, 4, 5
The most recent and highest quality study, published in 2023, highlights the importance of safe filler injection principles and the use of ultrasound guidance in preventing and managing complications 1. This study emphasizes the need for esthetic practitioners to be well-versed in injection anatomy and the prevention, recognition, and management of filler complications in the perioral area. By following these guidelines and recommendations, patients can minimize the risk of complications and achieve the best possible outcomes after lip injections.
