Oligopeptide-68 (also known as b-White or Pep01) is a synthetic peptide used in skincare to reduce hyperpigmentation by inhibiting melanin production, primarily through downregulation of the MITF transcription factor and tyrosinase activity. It is marketed as an alternative to traditional brightening agents for addressing dark spots and uneven skin tone.
