Research Overview
Minoxidil
Minoxidil has extensive human evidence for scalp hair regrowth in androgenetic alopecia and is a standard comparator in hair-loss trials. Its follicle effects are thought to involve potassium-channel modulation, vascular changes, and prolongation of the growth phase.
Leuphasyl
Pentapeptide-18 has published cosmetic and formulation literature supporting its use in anti-aging skincare. Evidence is strongest for topical cosmetic smoothing rather than deep structural remodeling.
