Niacinamide (Vitamin B3): A high-purity skin-perfecting agent that refines skin texture and strengthens the thin moisture barrier, effectively improving light reflection for a refreshed effect

BPC 157 Cream is formulated into an external dosage form of this polypeptide
The blend wins on three axes: it consolidates one reconstitution event instead of three (which reduces the probability of an aseptic technique error somewhere in the chain), it locks the three peptides into one ratio so that a single 0.20 mL draw delivers a fixed combination, and it consumes one storage slot in the fridge instead of three
Its hair-relevant evidence is largely mechanistic and indirect, drawn from the same properties documented in its extensive skin and wound-healing literature VEGF upregulation, angiogenesis, anti-inflammatory and antioxidant effects, stimulation of fibroblasts and extracellular-matrix synthesis, and broad gene-expression modulation
