Fillers replace the volume in your face, and by doing so, we can subtly change the shape and look of your face. Most of the time, this is done to avoid aging or dramatic changes. Fillers can be used to enhance your lips, fill your cheeks, straighten out your jawline, soften grooves underneath your eyes, and many more cosmetic alterations. It is important to distinguish that fillers are not used to fill in wrinkles. If you have frown lines and wrinkles, you also probably have volume loss, which typically requires two different treatments.
