<p data-start="171" data-end="702">COSRX 6 x Peptide Collagen Booster Toner Serum is a skin-renewal boosting facial essence designed to strengthen, hydrate, and revitalize the skin from the very first step of a skincare routine. Developed with a lightweight, toner-like texture, this booster absorbs quickly into the skin and delivers active ingredients efficiently without leaving a sticky or heavy residue. It works as a preparatory step that helps the skin better absorb subsequent skincare products while actively improving the overall look and feel of the skin.</p> <p data-start="704" data-end="1245">At the heart of the formula is a complex of six peptides that work together to support skin elasticity, enhance firmness, and visibly improve the appearance of fine lines and early signs of aging. These peptides also help refine the appearance of pores, support skin renewal, calm stressed skin, and promote a smoother, more resilient complexion. Niacinamide contributes to improved skin radiance and clarity by helping balance uneven tone and supporting the skin barrier, giving the skin a healthier and more refreshed appearance over time.</p> <p data-start="1247" data-end="1823">Hyaluronic Acid helps deliver and retain moisture within the skin, ensuring long-lasting hydration and a plump, smooth texture throughout the day. This balanced combination of peptides, Niacinamide, and hydrating ingredients makes the serum suitable for all skin types, including dry, oily, combination, and sensitive skin. The unscented and paraben-free formula is gentle enough for daily use and ideal for those who prefer minimal yet effective skincare focused on visible results. With regular use, the skin appears firmer, smoother, better hydrated, and naturally radiant.</p> <h3>Key Features</h3> <p data-start="1848" data-end="2493">This skin booster serum is formulated with six peptides that help improve skin elasticity, reduce the visible appearance of fine lines and wrinkles, refine pores, and support overall skin renewal.
