Filler is given via small injections into the specific areas to be treated. The results are immediate. The filler occupies space and gives volume. Hyaluronic acid draws water into the tissue in which it has been injected. This causes the skin hydration to improve and plumps the cell, resulting in a smoother appearance to the face and wrinkles to appear softer. The effects are product dependant, but will usually last 6-18 months.
