PALMITOYL HEXAPEPTIDE-52.

Valuable / SKIN CONDITIONING

This precision hexapeptide acts as a topical miorelaxant, specifically targeting muscle contractions responsible for dynamic expression lines. It offers a non-invasive approach to visibly reduce wrinkle depth and length, promoting a smoother, more relaxed skin appearance.

Science

Mechanism of Action

Palmitoyl Hexapeptide-52 functions by inhibiting the release of neurotransmitters, particularly acetylcholine, at the neuromuscular junctions in the skin. This modulation of neuronal signaling pathways prevents calcium entry into the neuron and interferes with the SNARE complex proteins, which are crucial for synaptic vesicle fusion and neurotransmitter exocytosis. By reducing acetylcholine release, the peptide effectively lessens muscle contractions associated with facial expressions, mimicking certain aspects of botulinum toxin's action in a non-invasive manner.

Key findings

  1. 01 As part of the X50® Myocept complex at a concentration of 0.001% (which includes Palmitoyl Heptapeptide-18), this ingredient achieved a 20% reduction in both the depth and length of wrinkles without the need for injections.
  2. 02 Studies indicate a 20% reduction in the appearance of expression lines was observed over approximately 28 days of use.

Transparency

Dusting Analysis

Not commonly dusted

Clinical evidence demonstrates significant efficacy at concentrations as low as 0.001%, which is within the recommended formulation range for optimal results. This indicates that the ingredient delivers active benefits at low concentrations and is not typically included merely for label appeal without functional impact.
