Chemical Description:

  • Dipalmitoyl hydroxyproline, often abbreviated as DPHP, is a derivative of the naturally occurring amino acid hydroxyproline.
  • It is commonly used in cosmetic and skincare formulations due to its anti-aging and moisturizing properties.
  • The molecular formula of Dipalmitoyl hydroxyproline is C40H77NO5.
  • It features a long chain structure with two palmitoyl groups attached to a hydroxyproline backbone.
  • The palmitoyl groups, each consisting of 16 carbon atoms, are long fatty acid chains derived from palmitic acid.
  • Hydroxyproline is a major component of collagen, providing structural integrity and resilience to the skin.
  • By attaching palmitoyl groups to hydroxyproline, the molecule becomes more lipophilic, enhancing its ability to integrate into the lipid matrix of the skin.
  • DPHP helps in reinforcing the skin's natural barrier function, which is crucial for retaining moisture and protecting against environmental aggressors.
  • It has been shown to stimulate collagen synthesis, which can help in reducing the appearance of fine lines and wrinkles.
  • The moisturizing effect of DPHP can lead to smoother and softer skin texture.
  • DPHP can improve skin elasticity, making it appear more youthful and firm.
  • It is known for its excellent skin-compatibility, making it suitable for sensitive skin types.
  • In cosmetic formulations, DPHP is often used in anti-aging creams, serums, and lotions.
  • It can also be found in products designed for dry or mature skin, as it provides long-lasting hydration.
  • The ingredient is valued for its ability to enhance the overall aesthetic appeal of the skin, contributing to a more radiant and healthy-looking complexion.
  • DPHP is typically used at concentrations ranging from 1% to 5% in skincare products.
  • The stability of DPHP in formulations is generally good, making it a reliable ingredient for long-term use.
  • In addition to its anti-aging benefits, DPHP can also provide a soothing effect, reducing skin irritation and redness.
  • Its ability to promote collagen production makes it a valuable ingredient for wound healing and scar reduction.
  • The use of DPHP in skincare products is supported by various scientific studies demonstrating its efficacy and safety.
  • As a multifunctional ingredient, DPHP offers a combination of hydration, anti-aging, and protective benefits for the skin.
  • Formulators appreciate DPHP for its versatility and ability to enhance the performance of other active ingredients in skincare products.
  • Consumers often notice visible improvements in skin texture and tone with regular use of products containing DPHP.
  • The inclusion of DPHP in a skincare regimen can contribute to long-term skin health and vitality.
  • Overall, Dipalmitoyl hydroxyproline is a highly beneficial ingredient in modern skincare, providing a range of effects that support youthful and healthy-looking skin.
