HEXAPEPTIDE-50.

Valuable / SKIN CONDITIONING

HEXAPEPTIDE-50 is a precision-engineered synthetic lipopeptide, often utilized in its palmitoylated form, Palmitoyl Hexapeptide-52. It functions as a topical muscle relaxant, effectively reducing the appearance of expression lines and wrinkles by mimicking neuromodulating effects.

Science

Mechanism of Action

This lipopeptide, primarily as Palmitoyl Hexapeptide-52, functions by inhibiting the release of acetylcholine into the synaptic cleft, thereby reducing muscle contractions responsible for the formation of expression lines. Its efficacy is frequently enhanced by advanced delivery systems, such as Cosmetic Drone®, which specifically target neuronal cells. The palmitoyl modification is integral for improving skin penetration and selective action, further contributing to the inhibition of calcium entry into neurons and the subsequent reduction of acetylcholine release.

Dusting Analysis

Not commonly dusted

Current research does not indicate widespread issues of under-dosing or 'dusting' specific to HEXAPEPTIDE-50. Efficacious concentrations reported in studies are consistent with its use in relevant product formulations.

Stability

Optimal stability is observed around a neutral pH of 7. Analogous palmitoylated hexapeptides maintain chemical integrity under standard cosmetic storage conditions, with powdered forms stable at -20°C for 1 to 3 years. Peptides are generally susceptible to enzymatic degradation in the skin.
