Key Ingredients

  • Pure Vitamin C: a highly efficacious antioxidant known for its ability to improve the appearance of skin aging; known to help boost radiance, improve texture, and visibly reduce the appearance of lines, wrinkles, and other signs of aging
  • Vitamin Cg: a vitamin C derivative that activates once absorbed into the upper layers of the skin's surface; with antioxidant benefits, it's frequently used in anti-wrinkle skincare products to help reduce facial lines over time
  • Fragmented Hyaluronic Acid: acts like a sponge and draws moisture into skin's surface layers and expands as it absorbs; it is known to help smooth and plump and is commonly used in skincare products intended to visibly reduce facial lines and refine texture
