It's not uncommon to experience bumps on the skin after receiving dermal filler injections, including in the body of the upper lip, cheeks, chin area, and along wrinkles and folds. This is a normal reaction and usually resolves within a couple of weeks. It may take several weeks for the filler to soften and settle on the skin, so you won't see the final results of your treatment right away. On average, people achieve the full effect within two weeks of receiving the injections.
For example, if you used hyaluronic acid fillers to create moderate improvements to your lips, these facial features can look very thick for a couple of days. In general, fillers that are injected into very mobile areas of the face, such as the lips, wear out more quickly than fillers given elsewhere.
