The lion's wrinkle is a wrinkle between the eyebrows, which can cause and angry look to the face. It is also vastly aging. In case of a deep lion's wrinkle we recommend hyaluronic acid, which will fill the furrow. The treatment is often performed after Botox, because these two treatments complement each other. Botox reduces the wrinkle and prevents the rapid degradation of injected filler. Hyaluronic acid lifts wrinkles and reduces furrows.
