After several weeks of testing I'm quite happy with the Intensive Serum. Actually, it is a white, slightly lotion with typical Nivea scent. My forehead wrinkles (particularly the distinctive 'frown lines') brought it not to disappear, but the facial skin still looks much fresher. Taken there is a narrow donor. By pressing lightly on the valve In use, it is very economical, it spreads easily on the skin and is quickly absorbed. It is refreshing and leaves no sticky feeling.
