Science
Mechanism of Action
Rhododendron Ferrugineum Leaf Cell Culture Extract operates as a sophisticated skin conditioning agent. Its rich composition of bioactive and polyphenolic compounds provides robust antioxidant protection, effectively neutralizing cationic radicals and mitigating signs of aging to promote a firmer, more youthful appearance. Critically, it maintains the integrity and function of skin stem cells, safeguarding them against UV-induced stress and boosting epidermal regeneration. The extract contains epigenetic factors and metabolites that preserve human skin stem cell function. Furthermore, identified flavonoids are considered probable senolytic molecules, contributing to skin rejuvenation by selectively eliminating senescent cells, while also delivering profound and sustained moisturizing benefits.
