It is generally recommended to wait at least 24 to 48 hours after getting lip fillers before kissing. This waiting period helps the lips heal, reduces swelling and tenderness, and lowers the risk of infection or disturbing the filler placement. Some experts suggest waiting 2 to 3 days before heavy kissing to ensure the filler has settled properly. After about a week, most swelling and bruising should subside, and normal kissing can usually be resumed safely. Gentle pecks might be acceptable sooner, but avoid vigorous lip contact during the initial healing phase to protect the results and prevent complications.
