Dr. Althea's Gentle Vitamin C Serum is a gentle brightening serum designed for sensitive and acne-prone skin. It combines 20% sea buckthorn extract, a fruit naturally rich in vitamin C, with a stable vitamin C derivative and niacinamide to fade dark spots, even out skin tone and revive radiance in dull skin. Green tea leaf water and allantoin soothe the skin. Its lightweight, non-sticky texture absorbs quickly and is suitable for daily use.
