Inducing Hormesis for a Lipofilling-like Action
By: Carine Bézivin, PhD, Lucas Meyer Cosmetics
The present article discusses a new approach to mimic lipofilling—the activation of hormesis, which is accomplished by the described encapsulated active designed to induce a transitory stress and initiate an overcompensation to reestablish homeostasis. This leads to the compensation of age-induced lipoatrophy and correction of wrinkles and folds, for a younger-looking appearance.
