Injectable hyaluronic acid (HA) is a type of temporary dermal filler. Hyaluronic acid is found naturally through out the body, with the highest concentrations in the joints, eyes, and skin. In the skin hyaluronic acid attracts water, which allows the skin to become more hydrated.
As we age, loss of volume leads to either a sunken or sagging appearance of the face, fine lines, wrinkles, folds, and thin lips. Injectable HA is used to reduce the appearance of fine lines and wrinkles, facial folds, and to create structure, framework, and volume to the face and lips. The effects of injectable hyaluronic acid are seen immediately.
The nasolabial folds, commonly known as "smile lines" or "laugh lines", are facial features. The nasolabial fold is the deep crease running from either side of the nose down towards the corners of the mouth. This crease becomes more noticeable as part of the natural ageing process. These folds can be corrected through injections with dermal filler restoring the lost volume and softening the appearance of these creases.
