Serum - the extra dose of care for your skin. Whether as a treatment or as a permanent addition to your skincare routine, a serum enhances and optimizes the effect of your cream. This cell-active serum with pentapeptides has been shown to reduce the depth of wrinkles. It supports the skin's natural collagen production, visibly smoothing the facial contours for an even skin tone. Application: Apply to cleansed face in the morning and/or evening. If desired, follow with a facial cream.
