• /bjnano.3.83 Abstract Skin can be damaged by the environment easily. Skin cream is an effective and rapid way to moisten the skin by changing the skin surface properties. Rat skin and pig skin are common animal models for studies and were used as skin samples in this study. The nano- and macroscale

Keywords: atomic force microscopy; damaged skin; pig skin; rat skin; skin cream; Introduction Skin is the largest outer organ. The skin structure of

• mammals is mainly composed of three distinct layers: subcutis, dermis, and epidermis [1][2][3][4][5][6]. Rat skin and pig skin are common models used for skin in health and cosmetics studies. Figure 1 shows the epidermis and dermis of pig and rat skin [6][7]. The epidermis is the outer layer of skin. It
