Fenugreek Seed Extract

aka trigonella foenum-graecum seed extract · methi extract

Appearing in clean-beauty lip formulas with volumising and conditioning claims. Trigonelline and mucilage content provide the mechanism basis for lip plumping and moisture-binding claims.

Benefits
  • Mucilage — hygroscopic film-forming on lip surface
  • Trigonelline with reported circulation-enhancing activity
  • Anti-inflammatory saponin content
  • Natural source of niacin (nicotinic acid derivative)
  • Conditioning fatty acid content
Example uses
  • Lip glosses with plumping claims
  • Conditioning lip masks
  • Volumising lip serums
  • Lip balms
  • Lip-focused skincare
Formulation notes

Water-soluble mucilage component; pH stable in cosmetic range. May contribute viscosity in aqueous formulations.

Watchouts

Topical volumising claims are based on theoretical circulation enhancement or mucilage film formation — not mechanistically equivalent to injectable fillers. Evidence base is largely brand-generated.

Clean beauty perception

Accepted in clean beauty as an Ayurvedic botanical. Lip volumising claims are not substantiated in independent RCTs.
