Thank you for your question. You are asking if the swelling from lip fillers will go down as they are swollen a day-and-a-half after treatment. You indicate you’ve had lip filler before. I can certainly give you some guidance about this, with just your one photo, and without a physical exam. I’m a Board Certified Cosmetic Surgeon and Fellowship-trained Oculoplastic Surgeon. I’ve been in practice in Manhattan and Long Island for over 20 years. I perform lip enhancement often in my practice, using softer hyaluronic acid fillers from the Restylane and Juvederm families. I also use blunt cannulas and minimal entry points to deliver the filler, while reducing reactive swelling due to needles and excessive pokes to enter the lips. You indicate that you have had lip fillers in the past, but you don’t indicate if this has happened before, if you have changed doctors, or changed filler material. If this hasn’t happened to you before, then doctor and their technique has changed, or the material has changed. Lip filler application technique can vary widely between doctors, so the number of pokes with the needle, using needles instead of cannulas, and the locations of the entry points can all affect temporary swelling. If the right amount of filler was used, swelling can be due to the reaction of the needle, not necessarily too much filler material used. However, if you have changed doctors, and your new doctor used more material than your previous one, then the swelling can also be due to excess filler. Since you indicate doing lip filler in the past, and worry that the effect of your current filler is “forever”. It sounds like you do have experience with hyaluronic acid fillers like Restylane and Juvederm, which do need maintenance as they are safely metabolized by the body with time. If you had a hyaluronic acid filler placed, then it can be safely dissolved with the injectable enzyme hyaluronidase immediately, or safely and gradually metabolized by the body with time. If you had another filler material placed like a semi-permanent or permanent filler, these are not easy to remove, and can in the body long-term. I don’t recommend semi-permanent or permanent filler to be applied anywhere because they can’t be reversed easily, and not all the material may be removed even with multiple removal surgeries. I do hope you used a hyaluronic acid filler so it can be reversed easily if results are not to your liking. I just hope you didn’t change to a longer lasting filler material, where the tradeoff for reducing maintenance procedures is a material that is not as safe, and more difficult to remove. I suggest you meet with your doctor for dissolving, or discuss other options if you had a semi-permanent or permanent filler placed in your lips. I hope you found this information helpful. Thank you for your question.
