Transdermal microneedle delivery array: LorealRecent Research Landscape

Inconsistent skin resistance leads to variable drug delivery depth and patient discomfort. These innovations utilize acoustic oscillation to modulate penetration force for precise dermal targeting.

What technical problems is Loreal addressing in Transdermal microneedle delivery array?

Uncontrolled thermal tissue exposure

(26)evidences

The stratum corneum acts as a barrier that limits the penetration of anhydrous formulas and active ingredients. Enhancing absorption through thermal cycling and controlled mechanical dispensing overcomes passive diffusion bottlenecks.

Inadequate localized dermal penetration

(21)evidences

Variations in skin elasticity and manual application lead to insufficient or uneven delivery depth. Precise control over penetration mechanics ensures reliable payload administration across different skin types.

Insufficient skin barrier permeability

(10)evidences

The stratum corneum acts as a physical barrier that prevents the passive diffusion of large peptides and polar hydroxyacids. Overcoming this transport resistance allows for the non-invasive systemic or localized delivery of high-molecular-weight compounds.
