From: Enhanced Skin Permeation of Anti-wrinkle Peptides via Molecular Modification
Effects of propylene glycol concentration on the cumulative permeation in 24 hrs and amount of drug in donor cell for different peptide analogues. Line graph: Amount of peptide analogue permeated through the skin after 24 hrs. Bar graph: Amount of drug loaded for each analogue at varying propylene glycol concentrations.
