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.
Matrixyl Synthe'6
Palmitoyl tripeptide-38 has a mix of published cosmetic research and formulation data suggesting benefits for skin appearance and matrix-support signaling. Its practical use is as a topical anti-aging ingredient in combination with hydrators and barrier-support agents.
