What it is
Ten amino acid peptide proposed to modulate the innate immune response by inhibiting TLR (toll-like receptor) 2 and 4 signalling, which are activated by UV, bacteria, and environmental pollutants; downstream reduction in IL-6 and IL-8 release is the proposed mechanism for calming visible surface redness; supplier-sponsored split-face studies suggest benefit in reactive skin types; independent replications are limited.
