Acetyl Tetrapeptide-3 + Biotinoyl Tripeptide-1: A Cosmetic Scalp Ingredient Guide
Compartir
Peptides are common in modern cosmetic scalp formulas because formulators can combine several appearance-focused ingredients in lightweight serums. Two ingredients in the ReGlow Hair formula are Acetyl Tetrapeptide-3 and Biotinoyl Tripeptide-1.
What are cosmetic peptides?
Peptides are short chains of amino acids used in many skincare and hair-care formulations. Different peptides are chosen for different cosmetic goals.
Acetyl Tetrapeptide-3
This peptide appears in scalp formulas marketed around the look of stronger, fuller hair and scalp conditioning. It should be evaluated as part of the complete cosmetic formula.
Biotinoyl Tripeptide-1
This is another peptide used in hair and scalp products focused on the appearance of hair quality and density.
Why pair multiple ingredients?
ReGlow combines peptides with caffeine, adenosine, biotin, botanical extracts, beta-glucan, hyaluronic acid, and zinc ingredients so the formula is not dependent on one headline component.
Avoid drug-style promises
Cosmetic scalp ingredients should not be described as treating alopecia or guaranteeing regrowth. ReGlow’s claims focus on fuller- and denser-looking hair.
