Wrinkles can be caused by a variety of factors, including age, sun exposure, and pollution. To reduce the appearance of wrinkles, it's important to use skincare products that contain ingredients like retinol, vitamin C, and hyaluronic acid, which can help to stimulate collagen production, brighten your complexion, and plump up your skin. Vichy's Liftactiv Supreme H.A. Wrinkle Filler contains 1.5% hyaluronic acid and vitamin C to help reduce the appearance of wrinkles and boost radiance.
