COSRX 6-Peptide Skin Booster Serum with Niacinamide & Hyaluronic Acid – Collagen-Support, Pore & Texture Refining

Skin Booster Serum with Niacinamide & Hyaluronic Acid Unlock stronger, healthier skin with COSRX’s 6-Peptide Skin Booster Serum, a carefully crafted formula that blends advanced peptides, skin-loving niacinamide, and hydrating hyaluronic acid for a complete skin rejuvenation boost. Designed to improve elasticity, refine texture, and enhance glow, this serum is a powerful addition to any daily skincare routine.

At the core of this serum is a potent blend of six peptides that help support collagen production, improve firmness, and promote a youthful, supple feel. With regular use, you’ll notice smoother skin, tighter contours, and a visible reduction in fine lines and sagging — key signs of aging skin.

Combined with niacinamide, the serum also works to brighten your complexion and even out skin tone. Niacinamide helps regulate excess sebum and minimize the appearance of pores, making skin look clearer and more refined. Meanwhile, hyaluronic acid draws in moisture and locks it deep within the skin, ensuring long-lasting hydration without heaviness or greasiness.

Because the serum is lightweight and absorbs quickly, it layers perfectly under moisturizer or sunscreen. Whether you follow a minimal skincare routine or a multi-step regimen, this serum fits seamlessly — leaving skin soft, plump, and glowing, ready for the day or night ahead.

Suitable for all skin types — including sensitive, oily, or acne-prone skin — this formulation steers clear of harsh irritants while delivering serious skin benefits. The gentle texture ensures comfort even for those who usually avoid heavier serums.

In short: COSRX 6-Peptide Skin Booster delivers on multiple fronts — boosting elasticity, refining pores, hydrating deeply, and promoting an even tone. Add it to your skincare routine and discover firmer, smoother, radiant skin that feels revitalized and resilient every day.
