A serum is applied in addition to the day and night care. It helps to reduce wrinkles and keeps the skin smooth and youthful. This intensive care contains highly concentrated active ingredients that improve skin tone and reduce the depth of wrinkles. Its anti-ageing effect is enhanced by its ultra-fine texture that allows a fast penetration into the skin. The skin is noticeably firmer and finer. The serum can be used on a regular basis or specifically for a limited period in order to respond to specific needs of the skin. For optimal effect we recommend to briefly heat the serum in the hands before applying it gently. It can either be applied in addition to the day or night cream or alone. It increases the effect of the day and night care and it protects your skin effectively against internal and external influences.
