The CKTUING Glutathione Niacinamide Serum is an effective whitening and anti-aging essence that combats dark spots, pigmentation, and dullness to uncover a radiant complexion brighter, smoother, more even. This serum is concentrated with Glutathione, Niacinamide, Hyaluronic Acid, Retinol, Collagen, and Glycerin for ultimate hydration, improved skin texture, and radiance.
Lightweight and liquid, this quickly absorbed formula works on several concerns: dark circles, puffiness, fine lines, dry skin, uneven tone, and hyperpigmentation. Apply daily to the face, hands, and body for brighter, clearer, and smoother-looking skin.
Perfect for anyone who wants a brightening serum for daily care.
Features:
✅ SPOTLESS BRIGHTENING POWER: Harness the power of the Glutathione-Niacinamide Complex for fast correction of dark spots, sun damage, and hyperpigmentation. Glutathione inhibits tyrosinase activity at the source of melanin production to ensure a visibly reduced discoloration and long-term whitening and clarity of the skin.
✅ REVERSE SIGNS OF AGING: Our powerful Retinol & Collagen formula accelerates cell renewal, dramatically smoothing texture while reducing the depth of fine lines and wrinkles. Active Retinol stimulates endogenous collagen synthesis to provide structural support for a firmer, more youthful lift and address concerns like fine lines around the eye area.
✅ MAXIMUM CORRECTION, MINIMAL IRRITATION: Featuring the ultimate skin buffer Niacinamide (Vitamin B3). This powerhouse active ingredient fortifies the skin barrier and drastically reduces characteristic peeling, dryness, and redness commonly experienced with high-performance Retinol. This synergy allows veterans and newcomers alike to use powerful actives consistently.
✅ PLUMPING HYDRATION & GLOW: Saturate your skin with deep, non-greasy moisture. Hyaluronic Acid and Glycerin join forces, their humectant power instantly plumping the skin, thereby immediately reducing visible puffiness and smoothing texture. This fast-absorbing formula locks in the essential hydration for continuous, "lit-from-within" radiance.
✅ FULL BODY RESTORATION: This Facial Essence is a powerhouse, fast-absorbing liquid formula that is non-comedogenic and lightweight; hence, it is safe and effective for correcting dullness, dark spots, and crepey skin texture on the Neck, Hands, and Body, making sure all the designated use areas are covered while providing firming benefits.
