Hello; I see collapses on your lower lip and nodulations on the sides of your upper lip. I don't know; if you have a previous history of filling issue. So, initially, anamnesis and examination are important for you. If you have had fillings before, the fillings may melt at different speeds; at different points too. This condition, may cause asymmetrical deformities on relevant lips. If you have never had fillers before, your lower lip; may be damaged by environmental factors, especially from the sun. Exposure to harsh environmental factors, not using sunscreen, and leaving lips without any moisture; can cause the skin; to become thin and flake in certain areas; increase fine wrinkles and cause depressions. In this case, I recommend for hyaluronic acid fillers. I use the brand of "Maili". Due to its elastic and gel properties, it does not cause any nodulation and stays on for a very long time. It is made by a special technology; the latest trend among hyaluronic acid fillers; which is Maili! You should try it. It moisturizes, protects and shapes for your lips. You should definitely try it!
