This is actually not a weird question at all and it's something a lot of people wonder about but don't always ask! The good news is that when done properly with the right amount and technique, lip filler should feel very natural both to you and to anyone else. Hyaluronic acid fillers integrate into your tissue and shouldn't feel like there's some foreign substance in your lips. In the first few days after treatment when there's still some swelling, your lips might feel a bit firmer or tighter than usual, but once everything settles they should feel soft and natural. Most people find that they can't really tell a difference in sensation after the first week or two. As for kissing, it shouldn't affect it at all! Your lips will still move naturally and feel normal to your partner. If your lips feel hard, lumpy, or obviously unnatural to the touch, that's usually a sign of either too much filler, improper placement, or the filler not being properly integrated into the tissue. This is yet another reason why choosing an experienced injector is so important - they know how to place the filler in a way that looks and feels completely natural. Some people report that their lips feel slightly more plump or cushiony, but in a good way that feels like naturally full lips rather than obvious filler!
