Hyaluronic acid wrinkle injection immediately reduces the appearance of wrinkles, leaving the skin smooth and giving the face a rejuvenated look. The treatment is minimally invasive and discomfort during injection is reduced. Effects that may occur following the injection are limited to local redness or bruising that generally disappear in about 24-48 hours. Injection of hyaluronic acid fillets also stimulates natural collagen production in the skin.
