Features:
✅ ACHIEVE K-BEAUTY GLASS SKIN GLOW: Korean-inspired Pink Peptides Serum is infused with potent Salmon DNA-PDRN that stimulates cellular renewal, speeds up healing, and boosts a visibly clear, luminous complexion with refined pores for that coveted "glass skin" effect.
✅ ADVANCED ANTI-AGING POWER: This formula combines the power of high-concentration Deep Collagen with Peptides, including Acetyl Hexapeptide-8, to firm and lift the skin while plumping it. This can be expected to reduce the appearance of fine lines, wrinkles, loss of elasticity, on the face, neck, and décolleté.

✅ BRIGHTEN DARK SPOTS & EVEN TONE: With powerful Niacinamide (Vitamin B3) and Vitamin C, it is formulated to visibly fade dark circles, hyperpigmentation, and age spots for a brighter, more even-toned, and luminous complexion.
✅CLEAN & GENTLE KOREAN FORMULA: This premium booster serum is Sulfate-Free and manufactured with a blend of Herbal and Organic ingredients for effective yet gentle care. It's ideal for everyday use on your hands, face, body, and neck to help keep a healthy, youthful appearance.
