BOSWELLIA CARTERII GUM ABSOLUTE.

Valuable CAS 89957-98-2 / 8016-36-2 / PERFUMING

A concentrated resinous extract derived from Frankincense that functions as both a structural skin fortifier and a potent anti-inflammatory agent. Rich in bioactive triterpenoids, it is utilized in precision skincare to preserve the dermal matrix and enhance tactile smoothness.

Matrix Metalloproteinase (MMP) Inhibitor Anti-inflammatory Natural Fragrance Dermal Conditioning

Science

This absolute operates through the targeted inhibition of 5-lipoxygenase (5-LOX), a primary enzyme in pro-inflammatory pathways. Furthermore, it serves as a dermal shield by suppressing matrix metalloproteinases (MMPs), specifically inhibiting collagenase by up to 85% and elastase by 60%, thereby preventing the enzymatic degradation of collagen and elastin fibers.

Key findings

  1. 01 A 2010 clinical study demonstrated that 0.5% boswellic acids significantly improved skin elasticity and reduced fine lines within a 30-day window.
  2. 02 2022 in vitro research confirmed that resin fractions at 200 µg/mL provide high-level protection against the enzymes responsible for skin sagging and wrinkle formation.
