In the rapidly evolving world of cosmetic science, clarity and authenticity matter more than ever. Lubrizol, the global leader in advanced beauty ingredients, is setting the record straight: not all peptides labeled as Acetyl Hexapeptide 8 are created equal. Only Lubrizol supplies the original, clinically validated Argireline® peptide—the world’s first cosmetic ingredient to target expression wrinkles by attenuating muscle contraction.

Ingredient Name ≠ Proven Performance
