Mibelle Biochemistrylauncheda new stem cell active basedon alpine rose.PhytoCellTec Alp Rose (INCI:Rhododendron Ferrugineum Leaf Cell Culture Extract (and) Isomalt (and) Lecithin (and) Sodium Benzoate (and) Lactic Acid (and) Water (aqua)) is said to protect skin against UV stress, increase skin stem cell vitality, boost epidermal regeneration and improve skin barrier function.

Alpine roses are Swiss flowersthat grow at altitudes of up to 3,200 m. In this environment, they must adapt to extreme conditions such as the cold, UV and dryness. The leaves of these roses, therefore, were sourced to create an active thatprotects skin stem cells against environmental stress factors and improves their function.

Skin's ability toprotect the human body from the environment relies heavily on the renewal and repair of the skin barrierby the epidermal stem cells. But environmental changes and aging impair the skin barrier leading to a drier, more fragile skin and accelerated aging.

To createthe active, the companyemployed itsPhytoCellTec technology to obtainthe stem cells from alpine rose leave, which wereincorporated in a water-soluble powder. Thesealpine rose stem cells contain epigenetic factors and metabolitesthat are able to preserve the human skin stem cells function. After creating the active, the company used its Progenitor Cell Targeting technology,to show thattheingredientincreases the vitality of epidermal stem cells by helping them to maintain their stem cell characteristics and protects these stem cells against environmental stress.

Thealpine rose active is recommended for:advanced stem cell cosmetic formulas, face and body care to protect stem cells against environmental stress and every weather formulations. Formulators can incorporate the active:at 0.41%, by dissolving it into the aqueous phase andby adding itpre-solved during the cooling phase (<60 C). The active is dissolvable at up to 20% in water and it is stable up to 60C for a short time.
