Most patients can receive further lip injections 3-6 months after their initial treatment. However, the exact timing may vary depending on the individual’s healing process and the amount of filler used in the initial treatment. It is also recommended to wait at least 2 weeks for swelling to subside before receiving additional injections. Additionally, it is recommended to avoid alcohol for at least 24 hours after receiving lip fillers and to drink plenty of water to reduce the risk of excessive swelling. It is normal to experience some swelling and bruising after lip injections, which should subside within the first 2 weeks.
