Eriobotrya Japonica Leaf Powder, typically formulated as an extract, is a multifaceted botanical ingredient renowned for its potent antioxidant, anti-inflammatory, and pro-collagen properties. It actively supports skin health by mitigating oxidative stress, soothing irritation, and contributing to a more even, resilient, and youthful complexion.

Summary

Antioxidant Skin-Conditioning Humectant Anti-inflammatory Anti-aging Skin Brightening Antimicrobial Anti-acne

Science

Mechanism of Action

This ingredient operates through several sophisticated pathways to optimize skin function. Its potent antioxidant capacity stems from a rich profile of polyphenols, flavonoids, and triterpenes, which efficiently neutralize free radicals. Anti-inflammatory actions are mediated by inhibiting inflammatory cytokine production, such as nitric oxide and TNF-α, alongside downregulating NF-κB activation and MAPK phosphorylation. It actively targets signs of aging by stimulating collagen and hyaluronic acid synthesis, while compounds like ursolic, maslinic, corosolic, and pomolic acids help preserve dermal integrity by hindering collagenase and hyaluronidase activity. Furthermore, it contributes to skin brightening by inhibiting melanogenesis, exhibits antimicrobial effects against P. acnes, and acts as a 'moisture magnet' to enhance skin hydration.

Key findings

  1. 01 An ethanol extract demonstrated anti-inflammatory effects by significantly reducing lipopolysaccharide-induced nitric oxide and tumor necrosis factor-alpha levels in RAW 264.7 cells. It also exhibited anti-melanogenic activity and was evaluated as non-irritant in in vitro skin and eye irritation tests.
  2. 02 An ethanol extract displayed significant antioxidant activity, achieving 86% 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging capacity and 50% superoxide dismutase (SOD)-like activity.
  3. 03 The leaf extract stimulated approximately 52% procollagen synthesis activity in fibroblasts and exhibited high DPPH (97.19%) and ABTS (96.91%) radical scavenging activities.

Sensitization risk Low

Eriobotrya japonica leaf ethanol extract (EJEE) at 0.5% (w/v) was evaluated as a non-irritant substance in in vitro skin and eye irritation tests. However, some individuals may experience a rash from products containing loquat leaf extract, suggesting a recommendation for patch testing. While the European Medicine Agency (EMA) assessed the whole leaf powder for oral intake, determining a chronic No Observed Adverse Effect Level (NOAEL) of 87.7 mg/kg/day, this data is not directly applicable to topical cosmetic use. FEMA GRAS status for flavoring purposes indicates general recognition of safety for ingestible forms.
