LITCHI CHINENSIS FRUIT EXTRACT.

Valuable CAS 91722-81-5 / SKIN CONDITIONING

Litchi Chinensis Fruit Extract is a versatile botanical ingredient derived from the litchi fruit, demonstrating clinically proven benefits for skin health. It actively works to enhance skin brightness, improve elasticity, and diminish the appearance of wrinkles. Beyond its anti-aging and brightening properties, it provides robust antioxidant protection, supports skin hydration, and helps maintain a balanced physiological pH.

Summary

Antioxidant Anti-aging Skin Brightening Hydration (Moisture-Magnet) Anti-inflammatory pH Balancing Skin Conditioning

Science

Mechanism of Action

This extract functions as a robust antioxidant, actively shielding the skin from oxidative stress induced by light irradiation and various environmental factors. Its anti-aging efficacy is attributed to its ability to inhibit elastase, collagenase, and MMP-2 activity, crucial enzymes involved in skin degradation. Skin brightening is promoted by suppressing melanin production through the inhibition of tyrosinase and tyrosinase-related protein mechanisms. Furthermore, it acts as a 'moisture-magnet' to enhance epidermal hydration and contributes to restoring the skin's optimal physiological pH, while also possessing anti-inflammatory properties.

Key findings

  1. 01 Clinical evaluation demonstrated significantly superior skin lightening, alongside marked improvements in skin elasticity and wrinkle reduction, compared to a placebo.
  2. 02 This concentration also exhibited skin lightening effects, though the significance was less pronounced than with the 0.1% concentration.

Dusting Analysis

Not commonly dusted

Clinical efficacy is observed at concentrations as low as 0.05%, with optimal benefits at 0.1%, suggesting that this ingredient is effective at low, meaningful percentages rather than being used in trace amounts for marketing purposes.

Stability

For optimal phenolic extraction and anthocyanin stability from litchi fruit pericarp, a pH of 4.0 and temperature of 60°C are most efficient. The ingredient should be stored in cool, dry, and tightly sealed containers, protected from heat and light exposure, to maintain its integrity for a reported shelf life of 6 months or longer.

Sensitization risk Low

EWG Skin Deep assigns a 'LOW' concern rating for potential cancer, allergies & immunotoxicity, developmental and reproductive toxicity, and use restrictions. Clinical patch tests performed with 0.05% and 0.10% litchi serums yielded a Mean Irritation Index (MII) below 0.2, indicating no or minimal irritation. While generally considered non-irritating, Paula's Choice advises caution regarding potential aesthetic or stability issues, and suggests a higher likelihood of irritation when formulated with other known problematic ingredients.
