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
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.
L-Ascorbic Acid, also known as Pure Vitamin C, is a highly efficacious antioxidant known for its powerful ability to improve the appearance of skin aging. Pure Vitamin C is essential for collagen synthesis and provides powerful antioxidant protection from skin damaging free-radicals.
Kiehl's chemists stabilized 10.5% Pure Vitamin C in a water-free formula more than 13 years ago and became pioneers in Vitamin C skincare products. Now, our formula includes 12.5% Vitamin C and Hyaluronic Acid.
