皮肤渗透性-抗皱肽性能的必要条件（英文版）

The skin offers various benefits and potential for peptide delivery if its barrier performance can be reduced temporarily and reversibly. As peptides possess high molecular weight, hydrophilic nature (in most cases), and ionizable groups in the structure, their skin delivery is highly challenging. Apart from this, they are susceptible to the proteolytic enzymes in the skin. Anti-wrinkle peptides, like other peptides, suffer from insufficient skin permeability, while most of them must pe
