Ultrasonic sound waves at a very specific vibration or frequency cause tiny, transient gaseous bubbles within the stratum corneum to rapidly expand and collapse, disorganizing the lipid bilayer and temporarily increasing permeability. In addition, the mechanical pressure of the sound waves creates a push-and-pull effect to facilitate the delivery of compounds through the stratum corneum layer. Through the process of Alma TED or “TransEpidermal Delivery,” we can increase the penetration of topical hair growth treatments through the top layer of skin, allowing more of the active ingredients to reach the hair follicles located below.
