| Origin of Peptide | Arginine-terminated peptide dendrimers of varying positive charge |
| Nature of Peptide/Cargo | Peptide dendrimers are wedge-like molecules comprising an amino acid branching core that is most typically decorated with various basic amino acids (e.g. Lys, His, Arg) on their head groups |
| Mechanism | Increased transepidermal water loss and decreased skin resistance due to the interaction of dendrimers with skin lipids |
