Abstract
The use of synthetic medication for treating alopecia is restricted because of systemic exposure and related negative effects. Beta-sitosterol (beta-ST), a natural chemical, has lately been studied for its potential to promote hair development. The cubosomes with dissolving microneedles (CUBs-MND) created in this study may be a useful starting point for the creation of a sophisticated dermal delivery system for beta-ST. Cubosomes (CUBs) were prepared by the emulsification method, using glyceryl monooleate (GMO) as a lipid polymer. CUBs were loaded with dissolving microneedles (MND) fabricated with HA and a PVP-K90 matrix. An ex vivo skin permeation study and an in vivo hair growth efficacy test of beta-ST were performed with both CUB and CUB-MND. The average particle size of the CUBs was determined to be 173.67 +/- 0.52 nm, with a low polydispersity index (0.3) and a high zeta potential value that prevents the aggregate formation of dispersed particles. When compared to CUBs alone, CUBs-MND displayed higher permeating levels of beta-ST at all-time points. In the animals from the CUB-MND group, significant hair development was observed. According to the results of the current investigation, CUBs that integrate dissolving microneedles of beta-ST are superior in terms of transdermal skin penetration and activity for the treatment of alopecia.
