Lip fillers are a popular cosmetic treatment. The lips are a crucial part of the face and play a key role in determining facial aesthetics. With age, vertical lip lines develop, and a person’s lips lose hydration and volume. By injecting hyaluronic acid-based lip fillers, we can regain this lost volume and hydration while also smoothening out lip lines. Lip fillers can also be used to sharpen and define lip borders, which is a popular choice in the younger population. There are different types of lip fillers. Low-concentration hyaluronic acid fillers are used to sharpen and define lip borders while higher-concentration products are used for mild to moderate lip volume enhancement. After administering local anesthesia, the procedure is virtually painless. Immediately after the procedure, the lips may appear swollen and the filler may feel lumpy. There may also be some bruising. The swelling gradually reduces over a few days and the lumpiness disappears with gentle massages. It is always better to start with a lesser amount of product, gradually adding to it only after a minimum rest and healing period of 2 weeks, that too, only if required. Since the lips are a dynamic part of the face, lip fillers get dissolved here quicker than in other regions; results typically last for about 6 months.
