Immediately after lip filler, it's common to experience some swelling and mild tenderness as the lips adjust to the treatment. This swelling typically peaks within the first 24-48 hours but will start to subside within a few days. As the swelling settles, the filler integrates with the tissue, leaving your lips looking plump, smooth, and naturally enhanced. The results will gradually reveal a hydrated, fuller appearance, enhancing your natural lip shape without looking overdone. Patience is key, as the final look will emerge after the initial swelling has fully gone down.
