Formulations contain many ingredients that are vital for some important function, such as providing stability. However, what does this “stuff” do in terms of helping or (usually) hindering the delivery of the all-important active? And how much of the active is actually available to deliver? A few simple questions and measurements, described here, can provide a wealth of insight.

Structured Surfactant Systems for Improved Lasting Deposition of Perfume on Skin and Hair
By: Caroline Mabille, PhD, Rhodia Aubervilliers R…
To maximize perfume delivery from structured cleansing formulations, the fragrance must be introduced before structuring the formulation into multilamellar vesicles. Structured formulations fragranced in such a way are shown here to improve perfume deposition and duration versus micellar systems, with no negative impact on perfume burst during use.

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.
