CALCIUM FRUCTOBORATE.

Valuable CAS 250141-42-5 / SKIN CONDITIONING - HUMECTANT

A nature-identical mineral complex that mimics the bioavailable boron found in fruits and vegetables. In precision skincare, it serves as a sophisticated electrolyte that bridges the gap between mineral replenishment and advanced anti-inflammatory therapy.

Anti-inflammatory Antioxidant Skin conditioning Anti-aging

Science

It functions as a bioactive boron carrier that stabilizes cell membranes by interacting with surface glycoproteins. Beyond its role as a superoxide ion scavenger, it modulates the cellular microenvironment by downregulating the expression of pro-inflammatory cytokines such as IL-1β and IL-6, while simultaneously influencing metabolic pathways like Akt and HRAS to support structural integrity.

Key findings

  1. 01 Topical application at 1-3% demonstrates measurable improvements in dermal thickness and visual wrinkle reduction.
  2. 02 Studies indicate potent systemic and localized reduction of C-reactive protein (CRP) and other inflammatory markers.
  3. 03 In-vivo models suggest protective effects against UV-induced cellular stress via modulation of HIF1α and PTEN expressions.
