Lately, skin care consumers have been developing increasing expectations when it comes to their skin care, especially facial care. In the post-pandemic world, the so-called skinification of beauty is on the rise. It means that beauty is not achieved by putting on makeup, but by actually improving the health of our largest and most visible organ, the skin. Improving the state of the skin at the cellular/molecular level – whether that means reducing wrinkles, fighting oxidative stress and skin aging, or promoting healthy cell turnover – is achieved by active ingredients that really do their job. Scientifically-based evidence for the efficacy of cosmetic formulations and actives has gained substantial importance. But in order for an active to reach its target in the skin, it must penetrate the upper skin layers in a sufficient concentration, which is sometimes limited due to solubility issues, stability issues, incompatibility with the formulation or poor penetration of the active into the skin. To improve efficacy, the concentration of the active should not be simply increased at will, as this involves a certain risk since there is often a lack of data on tolerability at higher concentrations . Therefore, it is better to increase the efficacy at a typical concentration through technologies that enhance performance.
