RAVENALA MADAGASCARIENSIS ARIL EXTRACT.

Insufficient Data / SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT, SKIN PROTECTING

Sourced from the aril of the Ravenala Madagascariensis, commonly known as the 'Traveler's Tree,' this extract is a hydrating active agent clinically shown to restore and maintain the skin's moisture balance. It precisely targets epidermal water regulation and enhances AQP3 aquaporin functionality, vital for deep skin hydration. Additionally, it offers antioxidant benefits and certain anti-enzymatic activities.

Summary

Hydrating Antioxidant Tyrosinase Inhibitor

Science

Mechanism of Action

This active ingredient operates by directly influencing the skin's hydration architecture. It adeptly regulates water flow within the epidermis, significantly enhancing the functionality of AQP3 aquaporins, which are crucial channels for water and glycerol transport. This action leads to improved hydration within the basal layers of the epidermis, preventing and ameliorating signs of dryness. Furthermore, it demonstrates broad-spectrum antioxidant capabilities through various assays (DPPH, FRAP, CUPRAC, metal chelating, phosphomolybdenum, ABTS) and inhibits enzymes like tyrosinase, potentially mitigating hyperpigmentation and contributing to overall cellular health.

Key findings

  1. 01 Clinical data, including patent US8697153B2, demonstrates efficacy in restoring and reinforcing skin hydration. Studies show significant activity in regulating epidermal water flows and enhancing AQP3 aquaporin function for improved hydration in basal skin layers. An emulsion containing 0.2% of the extract displayed hydration benefits on skin explants.

Stability

While an optimal pH of 5 with 10% sodium dodecyl sulfate (SDS) was found efficient for extracting the aril's blue pigment with enhanced stability, a general optimal pH range for the extract's stability in wider cosmetic formulations remains unspecified.

Not reviewed
Sensitization risk Unknown

No dedicated safety assessments from CIR, SCCS, or FDA for Ravenala Madagascariensis Aril Extract were identified. A toxicity study referencing *leaf* extracts (not aril) indicated deleterious effects in rats at high oral doses due to cyanogenic glucosides, but this information is not directly applicable to the topical safety profile of the aril extract.

Our Assessment

Verdict

Insufficient Data

Ravenala Madagascariensis Aril Extract presents compelling hydration benefits through its precise regulation of AQP3 aquaporins and offers antioxidant properties; however, a lack of comprehensive safety data regarding sensitization, irritancy, and comedogenicity currently limits a definitive holistic assessment for widespread application.
