Cos De BAHA H Hyaluronic Acid Serum

Cos De BAHA H Hyaluronic Acid Serum is a lightweight, water-thin Korean skincare serum formulated with a concentrated 10,000 ppm (1%) dose of pure hyaluronic acid, delivering intense hydration and visible plumping without heaviness or residue.

Suitable for both morning and evening routines, this serum sits comfortably after cleansing and toning but before moisturizer. Its fast-absorbing texture layers effortlessly under SPF in the AM and under richer creams or facial oils at night. Safe for use around the delicate eye area.

The formula keeps it refreshingly minimal. Sodium Hyaluronate — the bioavailable salt form of hyaluronic acid — works as the powerhouse humectant, capable of binding up to 1,000 times its weight in water to deeply plump and smooth skin. 1,2-Hexanediol rounds out the formula as a multitasking helper that enhances skin feel, supports ingredient stability, and provides mild antimicrobial preservation. The pH is calibrated to 6.5, making it compatible with all skin types including sensitive.

• Delivers deep, lasting hydration by drawing moisture from the environment into the skin’s surface layers, restoring suppleness to dry or dehydrated complexions.
• Visibly plumps and firms skin over time, reducing the appearance of fine lines and giving the face a smoother, more youthful look.
• Fragrance-free, paraben-free, and free from common irritants, making it a safe daily staple for reactive, sensitive, or compromised skin barriers.
• Pairs seamlessly with active ingredients like retinol, vitamin C, and exfoliating acids without interfering — boosting hydration while other actives work.

How to Use: After cleansing and any water-based toners, apply a few drops to damp skin and gently press in with fingertips for better absorption. Follow immediately with a moisturizer to seal in hydration. Use morning and night for best results. Perform a patch test on the neck before first use.
