LUPINE AMINO ACIDS.

Valuable / HAIR CONDITIONING, SKIN CONDITIONING

Derived from hydrolyzed lupine protein, Lupine Amino Acids are multi-functional skincare ingredients that enhance hydration and fortify the skin barrier. They are renowned for their ability to stimulate collagen and elastin production, leading to improved skin firmness, texture, and reduced appearance of fine lines.

Science

Mechanism of Action

Lupine amino acids act as potent humectants, attracting and retaining moisture to significantly boost skin hydration and reinforce the skin's natural moisturizing factors and barrier function. They actively stimulate the endogenous production of collagen types I, III, and IV, alongside elastin, while inhibiting collagen glycation and Matrix Metalloproteinases (MMPs), thereby enhancing skin firmness and elasticity. This ingredient also accelerates cellular activity and epidermal cell renewal, offers antioxidant protection by neutralizing free radicals, and demonstrates calming properties to mitigate skin irritation and redness.

Key findings

  1. 01 Significantly boosts collagen and elastin production, improving skin firmness and reducing the appearance of fine lines.
  2. 02 Supports skin barrier repair, strengthening the outermost layer and minimizing transepidermal water loss (TEWL).
  3. 03 Functions as a moisture-binding agent, elevating hydration levels and smoothing rough skin texture.
  4. 04 Aids in skin regeneration and recovery following dermatological procedures, promoting healing and reducing redness.
  5. 05 Reduces dullness and improves overall skin tone through enhanced texture and healthy cell renewal.
  6. 06 Enhances skin texture and firmness, inhibits collagen glycation, and stimulates collagen types I, III, and IV.

Stability

Lupine Amino Acids are heat-sensitive; for optimal stability and effectiveness, incorporate into formulations at temperatures below 40°C, typically during the cool-down phase of emulsions. Maintaining proper pH balance and ensuring compatibility with other preservatives are crucial to prevent degradation.

Safety

Safety Profile

CIR Status

Max tested
40%
Sensitization risk Low

The CIR Expert Panel considers amino acids safe at low concentrations in cosmetic products. Non-human in vitro studies indicate that lupine-derived amino acids are not dermal irritants. However, individuals with known legume allergies (e.g., peanut) are advised to perform a patch test due to potential cross-reactivity, though topical application is less likely to induce issues than ingestion. Mild skin irritation is rare, typically occurring only on compromised skin barriers or at elevated concentrations.
