Focus: Matrixyl (3000 & synthe'6)

Matrixyl®, a trademark of Sederma, represents a range of synthetic, signaling peptides that boosts the skin’s production of collagen, the protein responsible for providing strength and structure. Signaling peptides, or Matrikines, are chemical messengers instructing the cell to perform a specific function, stimulating the skin’s natural process. Derived from the amino acids paired with a fatty acid Palmitic Acid, each form of Matrixyl^® delivers distinct benefits, in addition to accelerating collagen production. 

• Matrixyl^® 3000
  • Palmitoyl Tripeptide-1 (original Matrixyl^®) stimulates collagen and gylcosaminoglycans synthesis, for firmer and smoother skin. Also known as Palmitoyl Oligopeptide or Pal-GHK, the tripeptide is comprised of the amino acids glycine, histidine and lysine.
  • Palmitoyl Tetrapeptide-7, inhibits the inflammatory response with the suppression of interleukins (IL-6). Defends collagen degradation from internal and external stressors – UVA/UVB light, pollution, and diet - for firmer and more resilient skin. Also known as Pal-GQPR or formerly Palmitoyl Tetrapeptide-3, the tetrapeptide is comprised of the amino acids glycine, glutamine, proline, and arginine.
• Matrixyl^® synthe’6^®
  • Palmitoyl Tripeptide-38 penetrates deep into the dermis to boost the production of collagen and the synthesis of hyaluronic acid, for firmer more radiant skin. Also known as Palmitoyl-Lysyl-Dioxymethiony-Lysine, the tripeptide is comprised of the amino acids lysine and methionine.

Skin Benefits:

• Matrixyl^® 3000
  • Lifts: Encourages gylcosaminoglycans (GAGs) synthesis, which fills the space between collagen and elastin within the dermis, improving sagging by 16.2% and elasticity by 5.5%.
  • Firms: Stimulates collagen synthesis (type I, IV, VII, XVII) reducing surface area of deep wrinkles by 39.4%, wrinkle density by 32.9%, and wrinkle depth by 19.9%.
  • Brightens: Improves skin roughness by 16% and skin tone by 15.5%.
  • Anti-Inflammatory: Inhibits inflammatory response and defends collagen degradation from internal and external stressors – UVA/UVB light, pollution, and glycation – delaying visible signs of damage by 5.5 years.
• Matrixyl^® synthe’6^®
  • Firms: Stimulates collagen synthesis of type by 105%, type III by 104% and type IV by 42% when applied twice daily at 2% concentrations for 60 days – decreasing wrinkle volume by 31% of the forehead and wrinkle surface by 28.5% of the eyes.
  • Lifts: Diminishes sagging by 28% when applied twice daily at 2% concentration within 60 days.   
  • Plumps: Boosts Hyaluronic Acid synthesis up to 174%, improving skin hydration, elasticity and moisture.
  • Smooths: Improves Laminin-5 production by 75%, an adhesion glycoprotein that helps to anchor the epidermis to the dermis.
  • Repairs: Increases Fibronectin A levels accelerating repair within the Extra Cellular Matrix (ECM).

Efficacy:

• Effective in topical applications ranging between 3-10% for Matrixyl^® 3000 and 2-4% for Matrixyl^® synthe’6^®.
• Sensitive to light and heat degradation, choose airless/opaque containers and store in a dark place.
• Peptides are sensitive to enzymes and acidic environments (lower than 4 pH). For best results, wait 20 minutes before applying Alpha Hydroxy Acid, Beta Hydroxy Acid, or Ascorbic Acid skincare.
• Well tolerated by all skin types – sensitive, rosacea-prone, and acne-prone.
