BETULA ALBA BARK EXTRACT.

Valuable CAS 84012-15-7 / FLAVOURING, FRAGRANCE, PERFUMING

Derived from the White Birch tree, this bioactive botanical extract is rich in triterpenes and polyphenols that serve as a high-performance skin regenerator. It provides a dual-action approach by reinforcing the lipid barrier while simultaneously calming inflammatory responses and protecting the skin's structural integrity.

Science

It functions by modulating calcium ion delivery to the epidermis, which accelerates the differentiation of keratinocytes and the production of structural proteins like Filaggrin and Involucrin. Additionally, it preserves skin architecture by inhibiting elastase enzymes and suppresses pro-inflammatory pathways through the targeted inhibition of the COX-2 enzyme.

Key findings

  1. 01 Clinical trials demonstrated that a 0.1% concentration significantly accelerated re-epithelialization in compromised skin sites.
  2. 02 In vitro testing confirmed an IC50 of 0.04% for COX-2 inhibition, indicating powerful anti-inflammatory potential at very low thresholds.
  3. 03 Usage levels between 1.0% and 5.0% are clinically recommended for maximizing antioxidant defense and barrier protein up-regulation.
