RAVENALA MADAGASCARIENSIS LEAF/STEM EXTRACT.

Valuable / SKIN CONDITIONING

Derived from the iconic Traveler's Palm, RAVENALA MADAGASCARIENSIS LEAF/STEM EXTRACT is a potent botanical active engineered to deeply enhance skin hydration. It actively works to preserve the skin's vital hyaluronic acid and offers protective antioxidant benefits, targeting dryness and overall skin health.

Summary

Skin Conditioning Hydrating Antioxidant Hyaluronidase Inhibitor

Science

Mechanism of Action

This extract functions as a multifaceted active agent primarily by restoring, maintaining, and reinforcing the skin's intrinsic hydration state, thereby preventing or diminishing the visible signs of dryness. Its observed hyaluronidase inhibitory activity suggests it contributes to the stabilization and retention of hyaluronic acid within the dermal matrix. Furthermore, the identified presence of flavonoids indicates an inherent antioxidant capacity, offering protection against environmental stressors.

Key findings

  1. 01 In a human skin explant study, extract concentrations ranging from 0.001% to 2% (dry weight) significantly restored and maintained skin hydration. Histological analysis revealed clear hydration labeling in the upper epidermal layers and moderate labeling within the stratum corneum, with young leaf extract proving particularly effective. A preferred effective concentration range was identified between 0.01% and 0.2% (dry weight).
  2. 02 A hydroalcoholic leaf extract (70% ethanol) demonstrated substantial hyaluronidase inhibitory activity, achieving 64.3% inhibition. This precise action suggests a direct role in protecting the skin's native hyaluronic acid from enzymatic degradation.
  3. 03 Various extract preparations (methanolic, ethyl acetate, aqueous) exhibited broad antioxidant activity across multiple assays (DPPH, FRAP, CUPRAC, metal chelating, ABTS) at concentrations from 1.25 to 100 µg/mL. This activity is attributed to its flavonoid content, indicating a general protective potential for skin health.
