Always looking sad? Fillers can make you look happier. The effects of aging or loss of volume and structure can give the corners of your mouth a downturned, drooping appearance making you look disgusted or sad, even when you are not. However, Fillers can help upturn your smile, leaving you with a much happier look. Without good support the corners of the mouth can simply droop; the good news is fillers can support the structure to uplift the corners.
