Summary

Antioxidant Skin-conditioning Humectant Soothing Anti-inflammatory Anti-melanogenic Brightening Collagen-boosting Astringent Detoxifying

Science

Mechanism of Action

This extract acts as a powerful antioxidant, diligently neutralizing free radicals to safeguard the skin against environmental stressors and mitigate premature aging. It significantly boosts skin hydration and elasticity, thereby strengthening the skin's natural barrier function. Possessing anti-inflammatory capabilities, it actively soothes irritated skin and reduces redness. Its anti-melanogenic effects are achieved through direct inhibition of tyrosinase activity and interference with the PKA/CREB pathway, which collectively suppress melanogenic enzyme activity and melanin production, leading to a noticeable brightening effect. Furthermore, its natural silica content promotes collagen synthesis, contributing to improved skin elasticity, firmness, and reduced wrinkle appearance. A gentle, non-irritating astringent action helps diminish pore size and refine skin texture, while its bioactive compounds also support skin detoxification for clearer, more balanced skin.

Key findings

  1. 01 Bamboo-leaf-flavonoids from Phyllostachys nigra var. henonis, at concentrations between 0.005% and 0.05%, were observed to accelerate the proliferation of rat skin cells and effectively inhibit pigment synthesis.
  2. 02 An ethyl acetate fraction of an 80% ethanol extract derived from Phyllostachys nigra var. henonis stem demonstrated in vitro tyrosinase inhibition with an IC50 of 240 μg/mL in B16F10 melanoma cells.
  3. 03 A methanolic extract from Phyllostachys pubescens shoot skins significantly reduced melanin production in melanoma cells by up to 78.4% at a 0.25% concentration.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Low

Phyllostachys Nigra Leaf Extract generally exhibits a favorable safety profile. Acute oral toxicity tests in rats and mice indicated it is non-toxic, with a maximum tolerated dose exceeding 10 g/kg body weight, and no observed mutagenic effects. A subchronic administration study for up to 90 days established a no-observed-adverse-effect level (NOAEL) at a daily dose of 4.30 g/kg. While considered safe for general use, a patch test is recommended for individuals with particularly sensitive skin to assess potential individual reactions. All cosmetic ingredients, including this extract, are subject to stringent safety regulations in the EU.
