BETULA COSTATA SAP.

Valuable CAS - / SKIN CONDITIONING

A nutrient-dense botanical fluid harvested from Manchurian Birch trees, serving as a superior, bioactive alternative to purified water in skincare formulations. It is naturally enriched with minerals, amino acids, and Vitamin B3 to fortify the skin's moisture barrier while actively calming inflammatory responses.

Summary

Skin conditioning Humectant Anti-inflammatory Soothing Barrier repair

Science

Mechanism of Action

Betula Costata Sap functions as a multi-pathway soothing agent by inhibiting the phosphorylation of MAPK and NF-κB signaling pathways, which downregulates the production of pro-inflammatory cytokines like IL-1β and IL-6. Structurally, its composition of soluble sugars and minerals mimics the skin's Natural Moisturizing Factor (NMF), enhancing the stratum corneum's ability to retain water and reducing transepidermal water loss (TEWL).

Key findings

  1. 01 A 4-week clinical evaluation of a 100% birch sap mist demonstrated a significant reduction in lactic acid sting test scores, improved blood perfusion to mitigate redness, and a measurable increase in hydration levels.
  2. 02 In vitro analysis on HaCaT keratinocytes confirmed that concentrations between 1% and 10% effectively attenuate inflammatory cytokines without inducing cytotoxicity.

While birch sap shows anti-inflammatory activity at 1%, many commercial products include it at 'dusting' levels (below 1%) purely for marketing claims. To achieve the clinical barrier-repair and redness-reduction benefits seen in studies, it should ideally represent a significant portion of the water phase or be used at concentrations exceeding 5%.

Stability

Naturally stable between pH 5.6 and 6.5. It is highly heat-sensitive; exposure to temperatures above 40°C during processing can degrade its inherent vitamins and sugars. Fermentation is a common technique used to enhance its molecular penetration and shelf stability.
