Key Ingredients

FRAGMENTED HYALURONIC ACID

This fast-absorbing form of Hyaluronic Acid acts like a sponge and 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.

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 skin aging. 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. The form of Vitamin C within our formula is synthesized via green science, making it a renewable ingredient.
