Wrinkles can have very different causes: when creases are caused by dryness, the skin lacks moisture, which in turn has an impact on elasticity and radiance. These types of wrinkles can be addressed relatively well with the right cosmetics. Fine lines and wrinkles can also be caused by the skin's natural aging process, in which hyaluronic acid and collagen production decreases. To a certain extent, serums and creams can counteract the natural skin aging process. A lack of hyaluronic acid can mainly be overcome by the external application of a hyaluronic acid serum; native collagen is available as serums, pads or masks. If the wrinkles have been deepened for years, e.g. through exposure to the sun, it becomes more difficult to compensate, as there is usually structural damage to the tissue. The situation is similar with relaxed muscles, e.g. in the nasolabial folds.
