What is it?

Matrixyl Sinthe’6® (or Palmitoyl Tripeptide-38) is an innovative peptide that acts similarly to matrikines, a group of natural peptides known for stimulating collagen synthesis and improving skin structure.

What is it used for?

Matrixyl Sinthe’6® stimulates the production of 6 fundamental components of the Skin’s matrix and the dermo-epidermal junction, including collagen I, III and IV, fibronectin, hyaluronic acid, and laminin 5. This combined action helps to "fill in" wrinkles and smooth fine lines, leaving the Skin with a plumper, firmer, and smoother appearance.

There are several types of peptides, distinguished by the signal they send to skin cells:

- Signal peptides: stimulate the production of proteins essential for the skin, such as collagen, elastin, proteoglycans, glycosaminoglycans, and fibronectin. Examples include: Palmitoyl Tripeptide-5, Palmitoyl Tripeptide-38.
- Metal ion and nutrient carrier peptides: facilitate the transport of trace elements or key nutrients (such as copper or biotin) essential for repair and regenerative processes. Examples include: GHK-Cu, which transports copper to support cellular regeneration and improve skin laxity and glow; and Biotinoyl Tripeptide-1, which delivers biotin directly to hair follicles, boosting the strength and density of hair and eyelashes. It is particularly popular in products designed to strengthen fragile eyelashes, eyebrows, and hair.
- Enzyme-inhibiting peptides: directly or indirectly block enzymes that break down proteins essential for the skin. Key examples include: Acetyl Tetrapeptide-5, peptides/amino acids derived from rice, soy, or silk.
- Neurotransmitter-inhibiting peptides: inhibit the release of acetylcholine at the neuromuscular junction, producing a botox-like effect. An example is Tripeptide-3, used as an intensive anti-wrinkle active ingredient.
