Beauty Blend combines GHK-Cu (glycyl-L-histidyl-L-lysine copper) and KPV (lysine-proline-valine) in a 50mg/20mg ratio. GHK-Cu is a naturally occurring copper peptide known for its role in stimulating collagen, elastin, and hyaluronic acid production, which are key factors in skin repair and anti-aging research. KPV is a tripeptide studied for its anti-inflammatory and tissue-healing properties. Together, they are used in laboratory studies to explore skin regeneration, wound healing, and cellular signaling pathway
