Chlorella Vulgaris Sh-Oligopeptide-1

Chlorella vulgaris sh-oligopeptide-1 is a small peptide derived from chlorella, a freshwater microalgae rich in proteins and micronutrients. In skincare formulations, this ingredient functions as both a conditioning agent and protective compound, working to maintain skin hydration and support the skin's natural defence mechanisms.The oligopeptide structure—essentially a short chain of amino acids—allows it to penetrate the outer layers of skin more readily than larger proteins, making it a versatile addition to serums, moisturisers, and targeted treatments.

The peptide works through multiple pathways. As a humectant, it draws water into the skin's outer layers, improving hydration levels. Its antioxidant capacity helps counteract oxidative stress caused by environmental factors like pollution and UV exposure, whilst its antimicrobial properties may support skin health by helping to regulate bacterial populations on the skin surface.The relatively small molecular size of oligopeptides allows some penetration into the epidermis, where they can exert conditioning effects on skin proteins and support barrier integrity from within.

This ingredient is most effective when used consistently as part of a daily routine. It works well in serums and lightweight moisturisers, and can be layered beneath or within other actives. No special preparation or timing is required; simply apply to clean, damp skin and allow to absorb before proceeding with the rest of your routine.

Generally well-tolerated across skin types with no common irritants. Those with algae sensitivities should patch-test first, though true algae allergies in skincare are uncommon.
