What the gurus are saying

This peptide serum earns praise as a holy grail for some, though irritation remains a real concern for others. Doctorly found it triggers redness and acne-like lesions, pointing to its low pH as the likely culprit. Anyone with sensitive skin or a history of irritation may want to patch-test first, or skip it altogether if your skin leans reactive.
