Bioidentical Collagen Serum

Key Benefits

• Formulated with 100% skin-identical vegan collagen.

• Supports the appearance of firmer, bouncier skin.

• Lightweight, breathable texture.

• Helps reinforce the skin barrier.

• Vegan and sustainably biofermented.

Bioidentical Collagen Serum features advanced molecular biofermentation technology to create 100% human skin-identical vegan micro collagen. Designed to mirror the collagen sequence found naturally in human skin, the formula delivers a targeted approach to supporting visibly resilient, supple-looking skin.

Cultivated using yeast cells through a sustainable biofermentation process, the collagen is refined into micro-molecules for enhanced absorption. This innovative method offers an alternative to plant-derived collagens that are not skin-identical and animal-derived collagens that are larger in structure.

The lightweight, breathable serum helps support the appearance of native collagen while reinforcing the skin barrier. Enhanced with plant-derived micronutrient cofactors, it helps defend against environmental stressors and promotes a smoother, restored-looking complexion. Suitable for daily use and formulated to align with vegan standards.
