BOSWELLIA CARTERII RESIN EXTRACT.

Valuable CAS 89957-98-2 / 8050-07-5 / FRAGRANCE, SKIN CONDITIONING, SMOOTHING, TONIC

Commonly known as Frankincense, this ancient botanical resin is a precision-aging powerhouse that targets both structural protein degradation and inflammatory pathways. It is particularly valued in high-performance skincare for its ability to refine skin texture and regulate lipid production in photoaged complexions.

Anti-aging Sebum Regulation Skin Conditioning Astringent Soothing

Science

It functions through a multi-targeted approach: inhibiting the 5-LOX enzyme to suppress pro-inflammatory leukotrienes, while simultaneously blocking elastase and collagenase enzymes to preserve the skin's structural matrix. Additionally, it offers antioxidant protection against oxidative stress and prevents the breakdown of moisture-retaining glycosaminoglycans (GAGs).

Key findings

  1. 01 Clinical evaluation of a 0.5% concentration showed significant reductions in fine lines and sebum excretion, alongside improved tactile smoothness over 30 days.
  2. 02 In vitro data confirms >85% inhibition of collagenase and 40-60% inhibition of elastase at concentrations of 200 µg/mL.
