The Science Behind Collagen III Amplifier
Biotech Collagen Type III: The Collagen of Repair
This advanced ingredient stimulates multiple types of collagen production in the skin, most notably Type III collagen, known for its regenerative and restorative properties. Collagen Type III helps rebuild elasticity, improve firmness, and restore skin density.
Multi-Level Collagen Support
In addition to Type III collagen, this serum helps promote Types I and IV, addressing multiple layers of the skin to visibly correct signs of collagen loss. Combined with hydrating peptides, glycerin, and barrier-supporting ingredients, the formula enhances both the structure and surface appearance of the skin.

1. Prep + Dispense
Begin by cleansing and drying the skin. Apply 4–5 drops of your antioxidant serum—C E Ferulic® in the morning or Resveratrol B E® at night—to the face, neck, and chest. Allow it to absorb completely before moving to the next step.
With consistent daily use, one bottle of antioxidant serum typically lasts 3 to 4 months.
Individual results may vary based on usage and amount applied per use.

After applying your antioxidant serum, dispense a thin layer of Collagen III Amplifier Serum onto the face, neck, and chest, gently pressing into the skin until fully absorbed.
