HYDROLYZED PHOSPHOLIPIDS.

Valuable / SKIN CONDITIONING

Hydrolyzed Phospholipids are biomimetic compounds integral to skin health, structurally similar to the skin's natural lipids. They are crucial for reinforcing the epidermal barrier, providing deep hydration, and enhancing the penetration of other active ingredients.

Science

Mechanism of Action

Operating as amphiphilic molecules, Hydrolyzed Phospholipids seamlessly integrate into the skin's natural lipid matrix, effectively restoring and maintaining the critical skin barrier. They possess strong humectant properties, attracting and retaining moisture to significantly improve skin softness and elasticity. Beyond their direct benefits, they function as natural emulsifiers, stabilizing complex formulations, and uniquely act as advanced delivery systems by forming liposomes or nanosomes that enhance the transdermal absorption of active ingredients. Their hydrolysis byproducts, such as free fatty acids, also contribute to maintaining optimal skin pH.

Key findings

  1. 01 In a study, a phospholipid-containing formulation demonstrated significant improvements in oily mature skin over 28 days, leading to measurable reductions in sebum content and pore size, alongside enhanced skin microrelief and hydration.
  2. 02 When utilized as a delivery system, phospholipid-based liposomes (encapsulating 0.5 mg/mL of an active ingredient) were observed to significantly decrease matrix metalloproteinase (MMP-1) expression and inhibit hyaluronidase in UV-exposed cells, suggesting a role in collagen preservation and wrinkle reduction.

Stability

Optimal stability and minimized hydrolysis occur within a buffered pH range of 4.0 to 6.5, with the lowest degradation rate observed around pH 6.5. Formulations must be buffered to prevent autocatalytic acid hydrolysis, though excessive buffer concentrations should be avoided to maximize shelf life.

Synergies

  • Enhances delivery of other active ingredients
  • Acts as a natural emulsifier for formulation stability

Conflicts

  • High temperatures (accelerates degradation)
  • Unbuffered low pH environments (accelerates degradation)
