Skin Doctors Youth Cell Activating Night Concentrate 30ml. YouthCell contains the latest plant stem cell technology (PhytoCellTec) to help delay the appearance of chronological ageing of the skin. These plant stem cells are sourced from a rare, long-living Swiss apple which has the unique ability to regenerate its cells once it falls from the tree. It is this characteristic, that when used on the skin, promotes the longevity of skin cells. YouthCell turns on the switch that tells your own skin stem cells to start producing again. Targeting the skin renewal process means younger, rejuvenated, more beautiful looking skin. YouthCell combines clinically proven PhytoCellTec plant stem cell technology with two of the most powerful anti-ageing peptides. It has been scientifically formulated to target your own skin stem cells for results you will see in just 30 days! YouthCell keeps you looking younger for longer. With its unique combination of plant stem cells and anti ageing peptides, YouthCell works not only at a cellular level to teach the skin how to look young again, but also at the skin's surface to treat the signs of ageing already visible. Attack ageing from the bottom up and the top down! The Plant Stem Cell technology (PhytoCellTec) works at the base layer of the epidermis, while the peptides, Matrixyl 3000 and Renovage, attack wrinkles and signs of ageing at the skin's surface. And when the 2 technologies meet in the middle, ageing is history! Clinically Proven Results: YouthCell Youth Activating Night Concentrate contains 4 active ingredients, each clinically proven by scientific trials. See the difference after just 4 weeks.
