Plant stem cells and no fewer than four anti-ageing breakthroughs for a highly-powerful serum.

It is a well-known fact that the skin protects itself during the day and repairs itself at night. The skin’s “clock genes” regulate these alternating protective and repair cycles, at least while the skin is young. As the skin ages, the expression of these genes decreases and the cells seem out of synch. They fail to distinguish between day and night, and no longer play a regenerative role.

This led to the idea of reactivating these youthful genes and restoring each cell’s natural synchronization process in order to ensure maximum protection during the day and full regeneration at night. More than ever, the cells function with maximum efficiency to repair, regenerate, protect, fortify and visibly rejuvenate the skin.

Day after day, the StemYouth Serum releases its power:

  • The skin is instantly smoother and plumped
  • The appearance of wrinkles is diminished
  • The skin’s firmness and elasticity increase
  • The complexion is exceptionally radiant
  • The skin glows and the youthful effect is increased
How to use & Ingredients
How to useMorning and evening, following a thorough skin cleansing, apply 1 or 2 pumps of StemYouth Serum to the face and neck and massage in gently. Then, apply the StemYouth Day or Night cream.


A liposomal preparation with stem cell extracts from the roots of the argan tree, a highly-resistant species found only in South-West Morocco. It is the first cosmetic active ingredient to target dermal stem cells. The result of detailed scientific and technological research, this exceptional active ingredient has demonstrated its ability to protect dermal stem cell activity by providing a favourable nutritive microenvironment.

PhytoCellTec™ Argan, an ultra-concentrated extract of argan stem cells:

  • Revitalizes and protects dermal stem cells
  • Optimizes the natural regenerating process of dermal stem cells
  • Reactivates all young cell functions
  • Restores collagen and elastin
  • Fights wrinkles and loss of firmness where they occur

PHYTOCELL® Malus Domestica

Liposomal preparation based on stem cells from a rare variety of Swiss apple recognized for its longevity potential.

The result of detailed scientific and technological research, this active ingredient has demonstrated its ability to protect epidermal stem cell activity by providing a favourable nutritive microenvironment and by shielding the stem cells from UV rays, even in low concentrations.

PHYTOCELL® Malus Domestica is also recognized for its proven anti-ageing and anti-wrinkle effects as a result of scientific testing on cell cultures and objective clinical studies. Wrinkles are smoother, the skin structure is stronger from the inside, and the skin is firmer and more attractive.

A revolutionary ingredient, PHYTOCELL® Malus Domestica helps maintain young-looking skin in a number of ways. Keeping adult epidermal stem cells in their microenvironment, far from any stress that could trigger a change, helps preserve the skin’s youthfulness.



Orsirtine® is a botanical rice extract that stimulates the expression and production of longevity proteins in skin cells. By boosting the production of sirtuins, Orsirtine® increases skin’s youthfulness and helps fight the signs of ageing by:

  • Promoting the cells’ optimal function
  • Favouring the protection of DNA
  • Protecting the skin from outside aggressions In other words, Orsirtine® allows the skin to stay younger-looking longer



Each time a fibroblast divides, the telomeres—located on the ends of the chromosomes—are shortened, reducing their ability to further divide. When the telomeres reach a certain length, the cell’s ability to replicate stops and cell senescence begins. Senescent fibroblasts are cells that undergo major morphological and metabolic changes. The main consequences are a decrease in the quality and quantity of the extracellular matrix components, i.e. mainly collagen, elastin, fibronectin and GAGs, and an increase in proinflammatory cytokines. These changes have a clearly negative impact on the structure and function of the skin, causing it to age more quickly.

Telomerase is an enzyme that prevents telomeres from shortening during cell division.

Vitasource is a purified extract obtained from the roots of Scutellaria baicalensis Georgi standardized in baicalin. This molecule induces the expression of telomerase in human fibroblasts. Consequently, it increases the active life of these key cells by nearly 10%, delaying their ageing. As a result, the skin stays younger-looking longer!



Factors such as UV radiation, even at low doses, can diminish the expression of “clock” genes, causing the cells’ circadian rhythms (alternating between day and night) to be out of synch. The cells can no longer adapt their behaviour to their environment; they cannot adequately protect themselves and repair becomes more difficult. As a result, they age more quickly.

Chronogen™ is a tetrapeptide that stimulates the expression of “clock” genes in order to help preserve biological rhythms and optimize cell protection and repair. It acts like a metronome, allowing the cells to achieve their full repair capacity.

Chronogen™ stimulates the natural synchronization process of cells in order to ensure optimum protection during the day and full regeneration at night. It also helps anticipate environmental aggressions before they damage the skin



Daily stress, a hectic lifestyle, lack of sleep, poor eating habits and smoking are all factors that lead to signs of fatigue, which gradually and insidiously mark your face and, more generally, your skin. As you age, the 7 billion toxins produced every day at all levels of the skin are no longer eliminated naturally, and literally suffocate the cells. The regenerating ability of these cells—and more specifically the ability of stem cells, which are more vulnerable to toxins—is greatly reduced. The skin cannot properly regenerate. It ages more quickly. You begin to notice definite warning signs, sometimes accompanied by bouts of fatigue: puffiness and dark circles under the eyes, dull complexion, strained features, prominent wrinkles, tired and less responsive skin.

Albizia julibrissin, also known as Persian silk tree, Mimosa tree or Constantinople acacia, originated in Asia; however, given the ornamental nature of its flowers, it can now be found on every continent, from the foothills of the Himalayas to the gardens of New York City.

This plant extract corrects strained features and lack of radiance using the following triple-action approach

  • Eliminating glycotoxins (decrease of 27%)—toxins produced through the natural phenomenon of glycation, which prevents effective skin repair while you sleep
  • Eliminating lipofuscin (decrease of 81%): This yellowish-brown pigment is made up of cell residues that accumulate in the skin with age, stress and fatigue. Lipofuscin gives skin a dull, parchment-like look
  • Stimulating the production of melatonin (increase of 38%)—naturally secreted by the body overnight, it acts as a powerful antioxidant and plays a universal cell repair role. If sleep is insufficient or of poor quality, the quantity of melatonin decreases.



Ergothioneine, also referred to as EGT, is a highly-active antioxidant that occurs naturally in rye. It recharges skin cell energy by stimulating cell oxygenation. According to a study published in 20071 , its antioxidant properties outweigh those of Co-Q10 and Idebanone.

This anti-ageing compound suppresses the expression of certain matrix metalloproteinases (MMPs). In other words, it prevents collagen and elastin from breaking down, keeps cellular components and DNA from being attacked by free radicals, and reduces inflammation.


The quantity of hyaluronic acid present in the skin drops by half between the ages of 20 and 50. Extremely popular in cosmetic medicine, this naturally occurring skin compound is an outstanding anti-ageing ingredient.

Its inclusion in the formula multiplies the level of water in the skin by 1000, providing powerful hydrating and plumping properties. Moreover, it helps the skin maximize its repair capabilities.
