June 2026 in “Drug Delivery and Translational Research” The study presents a solid microneedle booster (SMB) as an advanced microneedling platform for treating androgenetic alopecia (AGA). The SMB integrates spring-driven perpendicular stamping with simultaneous liquid dosing, improving microchannel reproducibility and early transport. Tests on porcine skin revealed that SMB achieved greater microchannel surface coverage and deeper penetration than a roller. It also enhanced early-phase permeation, accelerating hair regrowth when combined with minoxidil (MXD) in vivo. Histological analysis showed increased follicle enrichment in the SMB + MXD group. SMB provides a one-step, directionality-controlled microneedling method that enhances early transport and promotes follicular maturation, with potential for broader dermatologic applications.
