    What It Is
    A potent Vitamin C serum formulated with 12.5% Vitamin C and Hyaluronic Acid.
    Benefits
    Kiehl’s original Vitamin C serum is now formulated with even more Vitamin C. In addition to 10.5% L-Ascorbic Acid, this formula is infused with 2% Vitamin Cg and fragmented Hyaluronic Acid. Visibly reduce wrinkles and fine lines and boost radiance with this potent serum. Powerful-Strength Line-Reducing Concentrate is dermatologist-tested for safety and gentle enough for sensitive skin.
    Key Ingredients
    • Pure Vitamin C: L-Ascorbic Acid, also known as Pure Vitamin C, is a highly efficacious antioxidant known for its ability to improve the appearance of aging skin. In addition to antioxidant protection, Pure Vitamin C is known to help boost radiance, improve texture and visibly reduce the appearance of lines, wrinkles and other signs of aging.
    • Vitamin Cg: Vitamin Cg, or Ascorbyl Glucoside, is a Vitamin C derivative that activates once absorbed into the upper layers of the skin’s surface. With antioxidant benefits, this form of Vitamin C is frequently used in anti-wrinkle skincare products to help reduce facial lines over time.
    • Fragmented Hyaluronic Acid: This fast-absorbing form of Hyaluronic Acid is known for its ability to hold up to 1,000 times its weight in water. Acting like a sponge, it draws moisture into skin’s surface layers and expands as it absorbs. Hyaluronic Acid is known to help smooth and plump and is commonly used in skincare products intended to visibly reduce facial lines and refine texture.
