If you have depressions in your face then filler can be used to expand soft tissue. In general, fillers are used to replace natural substances in the skin (collagen, hyaluronic acid) lost due to aging and to improve wrinkles on the face. Filler is best used for dark circles under the eyes, to fill out the lips, to fill mouth lines, to reduce deep lines, to add more height to the chin and to add height to the nose. Filler can be used for other treatments such wrinkle reduction and scars but other options are better suited for this depending on the case. We don’t recommend using filler for large areas such as the forehead and the cheeks as filler tends to shift in those areas producing unsatisfactory results. We recommend the most people undergo temporary filler injections which last 6-12 months on average. These fillers can be dissolved with an anti-filler injection if the results are not to your liking. Semi-permanent fillers can last 2-10 years and in most cases can only be removed surgically. These fillers have a high rate of problems in certain areas over time so it is recommend to avoid them for most people.
