FAQs:

What is the signature scent of the PEPTIDE-132 products? The PEPTIDE-132™ products are infused with COSRX’s signature “Green Ivy” scent—a fresh, citrusy, and woody fragrance. Inspired by serene bamboo forests, it opens with crisp green notes and finishes with soft, clean woods, creating a refreshing and uplifting experience.
Exclusively developed for COSRX, this subtle, gender-neutral scent is loved globally for its light and calming feel.

How is PEPTIDE™ beneficial for hair? PEPTIDE-132™ is a patented repair peptide designed to protect and strengthen damaged hair. It bonds like puzzle pieces to keratin, the key protein in hair, filling in weakened areas and holding other beneficial ingredients in place. Made of three amino acids, this small-sized peptide (384.9 Da) penetrates deep into the hair cortex to repair broken bonds caused by physical and chemical damage. This helps restore hair strength and improves overall hair health.

Is PEPTIDE-132™ suitable for all hair types? Yes! The PEPTIDE-132™ product line is designed to work effectively across all hair types, including straight, wavy, curly, and coily.
Hair damage can occur every day from styling, brushing, or environmental exposure, even if it isn’t immediately visible. That’s why the patented PEPTIDE-132™ was developed to repair broken hair protein bonds and restore strength and elasticity from within.
Its ultra-light molecular weight allows deep absorption without any residue, making it gentle enough for daily use.

How do I build an effective haircare routine, and do I need the full PEPTIDE-132™ line to see results? While each product is clinically effective on its own, using the full PEPTIDE-132™ routine delivers significantly better results. In a 4-week clinical study, the 3-step routine (Shampoo, Treatment, and Oil Serum) improved hair protein bonding by 2.7x and softness by 1.8x compared to using a single treatment. This step-by-step routine repairs, strengthens, and protects, leaving hair visibly healthier and scalp balanced.
