Dipeptide-2 is an eye-care peptide commonly used in formulas targeting puffiness and under-eye fluid retention.
Its proposed mechanism involves ACE-related vascular signaling, and clinical evidence usually comes from multi-ingredient eye complexes rather than Dipeptide-2 alone. So it is a legitimate eye-care peptide, but the evidence should be described as blend-level, not stand-alone proof.
Information approach
Consumer-friendly summaries are informed by established cosmetic ingredient references such as INCIDecoder and Paula’s Choice Ingredient Dictionary, while avoiding turning ingredient-level evidence into medical claims about the finished product.
