Dipeptide Diaminobutyroyl Benzylamide Diacetate Oligopeptide-133

Dipeptide Diaminobutyroyl Benzylamide Diacetate Oligopeptide-133 is a synthetic peptide — a short chain of amino acids — developed for skincare formulations. Peptides are thought to communicate with skin cells and may help support the production of structural proteins like collagen.This ingredient functions as a skin conditioning agent and is typically included in serums and treatments targeting signs of ageing, particularly dynamic wrinkles caused by facial expressions.

This peptide is believed to work by signalling skin cells to maintain and support the structural proteins responsible for firmness and elasticity. By helping to preserve collagen and elastin fibres, it may reduce the depth and visibility of expression lines over time.It is typically formulated alongside other peptides and supporting ingredients to create a synergistic anti-ageing effect, rather than working in isolation.

Apply to clean skin as part of a serum or treatment, typically in the morning and evening. Allow the product to dry before layering other skincare steps. Results from peptide-based products tend to develop gradually over weeks to months of consistent use, so patience is important. Combine with broad-spectrum SPF during the day, as peptides work best when skin barrier health is optimised.

This ingredient is generally well-tolerated in skincare formulations. Those with very sensitive skin should patch test first, though peptides are typically considered low-irritancy.
