November 2011 in “Journal of the European Academy of Dermatology and Venereology” Effective acne scar treatment should use combination therapy based on specific skin changes.
January 2026 in “Open MIND” A recent study explores a non-androgen pathway for treating androgenetic alopecia (AGA) by targeting the PIEZO1 and MLCK axis, which is implicated in follicular miniaturization due to connective tissue sheath hypercontractility. The research screened a library of 2,529 natural compounds using advanced computational methods to identify candidates that could potentially inhibit this pathway, with promising bioavailability for topical application. However, these findings are purely computational and require further *in vitro* validation, with no current clinical claims or products available.
