MMP Inhibitor Collagen Booster Anti-Glycation Agent Firming Agent Humectant Skin Renewing Photoaging Protection Anti-inflammatory Emollient Skin-Conditioning Agent

Science

Mechanism of Action

Lupinus Albus Protein effectively mitigates the breakdown of the extracellular matrix by inhibiting Matrix Metalloproteinases (MMPs), specifically MMP-2 and MMP-9, which are activated by factors like sun exposure and inflammation. Its refined peptide extracts are instrumental in preventing collagen glycation and significantly stimulating the endogenous production of collagens I, III, and IV. This action, coupled with the reinforcement of dermal-epidermal adhesion and contractile fiber protection, demonstrably enhances skin firmness. Furthermore, this ingredient forms a protective, humectant film on the skin's surface, optimizing moisture retention, while simultaneously stimulating cellular renewal for a visibly smoother and more vibrant complexion. It also offers prophylactic benefits against chronic photoaging, acute sun-induced effects, and various inflammatory conditions.

Key findings

  1. 01 Inhibition of MMP-9 activity in colon cancer cells (in vitro) at a concentration of 10 µg·mL-1.
  2. 02 Lupin peptide extracts demonstrate efficacy in preventing or increasing skin firmness, inhibiting collagen glycation, and stimulating the expression of collagens I, III, and IV. These extracts also protect the dermis against loss of contractile fiber function, reinforcing skin firmness.

Stability

Optimal solubility for lupin proteins is dramatically increased above pH 6, with peak solubility observed at pH 8 and 9 (93.7% and 94.5% respectively). Formulators should precisely avoid the isoelectric point range of pH 4-5 to ensure optimal solubility and stability in cosmetic preparations.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Low

While the Cosmetic Ingredient Review (CIR) has not specifically reviewed Lupinus Albus Protein, plant protein products are generally recognized as safe food additives by the FDA. Dermal irritation studies on Hydrolyzed Lupine Protein indicated no irritant response or sensitization in animal models. Although ingestion of legumes like lupine can trigger Type 1 allergic reactions in individuals with peanut allergies due to cross-reactivity, this concern pertains to oral consumption, not topical application.
