A vegetal story

Argemone mexicana + Polysaccharides

Naolys’ objective in creating this unusual new cellular plant complex, consisting of a Mexican poppy cell and polysaccharides, is to provide a comprehensive solution to chronic and temporary dry skin. A unique synergy between the active molecules synthesized by the cell and the natural polysaccharides that it has absorbed results in a complete moisturizing action.
The Mexican poppy, originating from Mexico and the West Indies, has been naturalized in many arid tropical zones of the globe, where it is used as a medicinal plant. Polysaccharides derived from plants, consisting of long chains of simple carbohydrates, are recognized for their water retention capacity. Enriching a plant cell with polysaccharides thus increases the bioavailability of all the active molecules that it contains.

Natural skin hydration

Because dry skin involves a combination of numerous imbalances at several levels, such as the quantity of water and the quality of the intra and extra-cellular water barrier, it is necessary to correct these imbalances at their source. For softer, suppler, more efficient skin. For skin that looks younger for longer.

How it works ?

HydraSourcing [AM+PS] restores the necessary balances to an optimal level of hydration

Water is a vital component of the human body: we are 65% water. However with age, the proportion of water decreases, because as tissues such as the skin become older they tend to dehydrate. The upper part normally contains between 13 and 15% water. Like the other organs in the human body, the skin cannot store water and it evaporates from the skin’s surface on a continuous basis. Due to numerous factors (dry atmosphere, frequent use of soap, exposure to wind and sun, etc.) the skin sometimes becomes dry, it can then become rough and less flexible, making wrinkles more apparent. Women in particular have skin that tends to become drier with age. Various components are responsible for the amount of moisture in the skin, it is therefore necessary to act on several moisture regulating mechanisms in order to keep this at an optimal level.

Acts on the fundamental mechanisms for moisture regulation



There is water in the skin’s two main layers: the dermis and the epidermis. In the dermis, it is linked to protein macromolecules, glycosaminoglycans. They retain water, some of which is regularly transported to the epidermis: they form a reservoir of water for the epidermis. In the epidermis, water is found in and around the keratinocytes. The free water diffuses naturally up to the skin’s surface and evaporates.

HydraSourcing [AM+PS] encourages the presence of water in the skin by increasing the amount of water in the epidermis and dermis.



Skin hydration is inextricably linked to the transformation of keratinocytes known as keratinisation. Keratin creates components which slow the water down on its way to the surface, such as the NMF (Natural Moisturizing Factor) in the corneocytes, and, mixed with sebum, the hydrolipid film on the skin’s surface. Combined with lipids derived from the decomposition of keratinocytes in the granular layer, which form a mortar between the corneocytes, they enable better control of the transepidermal flow, thereby trapping water and keeping it in the corneous layer.

HydraSourcing [AM+PS] strengthens the skin’s water barrier by increasing the presence of lipids, NMF and the hydrolipid film.


Thanks to its multidirectional action on water flow and the corneous layer, HydraSourcing [AM+PS] increases skin hydration.
