The Cosrx Peptide Serum is designed to improve skin structure and early signs of aging using a blend of six peptides. These peptides work to support firmness, refine texture, and reduce the appearance of fine lines. As a result, the skin gradually becomes smoother, more lifted, and more resilient with continuous application.
Unlike heavy anti-aging creams, this booster has a lightweight texture that absorbs quickly without residue. In addition, it integrates easily into existing routines and can be layered with other treatment serums without conflicting. The formula also supports barrier stability, which is essential for preventing premature aging related to irritation and dehydration.
With routine use, the serum helps prevent loss of elasticity while improving the look of dull or fatigued skin. Moreover, the generous 150ml size makes it suitable for long-term use or for application on the neck and jawline as well. Ultimately, the Cosrx Peptide Serum serves as a daily aging-prevention step that strengthens the skin while enhancing overall texture and firmness.
