Product Technical Details

Product Overview

DSIP (δ-Sleep Inducing Peptide) is a naturally occurring nonapeptide originally identified for its role in modulating sleep cycles. With the sequence Trp-Ala-Gly-Gly-Asn-Ala-Ser-Gly-Glu, this peptide has gained significant interest in the cosmetic and nutraceutical industries due to its demonstrated antioxidant, neuroprotective, and calming biological activities. As a high-purity bioactive ingredient, DSIP supports skin homeostasis and helps mitigate oxidative stress induced by environmental aggressors.
