Tripeptide-32 description

Tripeptide-32 is a synthetic peptide with the “tri” (meaning three) designation referring to this peptide’s mix of the amino acids proline, serine and threonine. One of its trade names is SpecPed® TR32P. Cosmetics company Estee Lauder refers to this peptide as Chronolux™. Tripeptide-32 has hydrating benefits for skin, as most peptides do. The more remarkable claims around this peptide state that it can activate genes that regulate skin’s biological clock, allowing it to repair damaged cells at night in addition to fighting the emergence of wrinkles by day. Unfortunately, there just isn’t much independent research backing these claims as true. That isn’t to say that it might not be revealed to be the case later, but for now, it’s best to rely on this peptide more for its hydrating abilities and less on its effect on skin cells overnight.
