ANOGEISSUS LEIOCARPA BARK EXTRACT.

Valuable / SKIN CONDITIONING, SKIN PROTECTING

A high-performance botanical extract derived from the African Birch tree, specifically engineered to reinforce the skin's structural scaffolding. It acts as a bio-booster for Vitamin C, enhancing collagen synthesis and protecting elastic fibers to visibly reduce wrinkle depth and improve skin firmness.

anti-aging brightening antioxidant collagen-booster

Science

This extract functions via a multi-pathway approach: it optimizes the transport of Vitamin C into fibroblasts to stimulate collagen production while simultaneously inhibiting matrix metalloproteinases (MMP-2 and MMP-9) which break down the dermal matrix. Furthermore, it protects fibrillin-1—a glycoprotein essential for elastic fiber integrity—and inhibits tyrosinase activity to modulate melanin production and brighten the complexion.

Key findings

  1. 01 A 14-day in vivo study involving 19 participants demonstrated that a 2% concentration significantly reduced visible wrinkle depth compared to a placebo.
  2. 02 In vitro trials confirmed the extract increases Vitamin C incorporation into skin cells, effectively maintaining the dermo-epidermal junction and collagen density.

Because it is a potent botanical, many brands include it at 'label claim' amounts (below 0.1%) to leverage its exotic name. However, clinical data suggests a minimum of 0.5% is required for biological impact on Vitamin C uptake, with 2.0% being the benchmark for rapid anti-wrinkle results.
