Key Ingredients

• Biodesigned Signal Peptide: Biomimetic, five amino acid peptide that supports active melanocytes and keratinocytes to help strengthen eyebrows, enhance brow color, and increase visible brow density

• Biodesigned Keratin: Biomimetic, full-length keratin protein that helps supplement keratin where it’s most needed to strengthen the brow follicles
• Biodesigned Hepatocyte Growth Factor: Biomimetic, full-length signal protein that collaborates with natural growth factors to support anagen (growth) and catagen (transition) phases to promote visibly thicker, fuller brows
• Biodesigned Isopropyl Cloprostenate: Biomimetic, analog of prostaglandin included at a specific concentration to safely and effectively support natural brow growth for visibly enhanced eyebrows
