The simplest model is a two-dimensional (2D) co-culture system, which helps understand the direct and indirect cell-to-cell interactions between immune and structural cells; however, it has limitations when observing three-dimensional (3D) interactions or reproducing skin barriers.

More commonly used models to conduct skin-permeation studies are ex vivo human or animal skin. Through the standardization of protocols and techniques, the available skin models can be useful as surrogate models for in vivo human skin to evaluate the bioequivalence of topical products.

The skin is made up of 3 layers: Epidermis Dermis Subcutaneous fat layer (hypodermis) Each layer has certain functions. Epidermis The epidermis is the thin outer layer of the skin. It consists of 2 primary types of cells: Keratinocytes. Keratinocytes comprise about 90% of the epidermis and are responsible for its structure and barrier functions.

The skin is composed of two main layers: the epidermis, made of closely packed epithelial cells, and the dermis, made of dense, irregular connective tissue that houses blood vessels, hair follicles, sweat glands, and other structures. Beneath the dermis lies the hypodermis, which is composed mainly of loose connective and fatty tissues.

The indentation approach can also be used to obtain the viscoelastic properties of the human skin. Mostafavi Yazdi et al. utilized the ramp-relaxation experiment with a generalized Maxwell model, which was fitted to the experimental data, to find the viscoelastic properties of the thigh skin (Yazdi et al., 2018).In the ramp-relaxation experiment, the indenter penetrates to the human skin for a.

In the literature, such models are called skin model, skin phantom, skin equivalent, synthetic skin, skin substitute, artificial skin, skin replica, skin model substrate etc. depending on the research field. Physical models of human skin have been proposed and described in numerous studies concerning testing and development of materials and.

The skin model has been developed to enrich the nominal idealized geometry considering physical shapes. The concept stemmed from the theoretical foundations of Geometrical Product Specification (GPS) [7] and the two acknowledged axioms of manufacturing imprecision and measurement uncertainty [8].

Skin Model

Reconstructed human skin models are a valuable tool for drug discovery, disease modeling, and basic research. In the past decades, major progress has been made in this field leading to the development of full-thickness skin models (FTSms) better representative of the native human skin by including the cellular cross talk between the dermal and epidermal layers. However, current available FTSms.

Stratum Basale. The stratum basale (also called the stratum germinativum) is the deepest epidermal layer and attaches the epidermis to the basal lamina, below which lie the layers of the dermis. The cells in the stratum basale bond to the dermis via intertwining collagen fibers, referred to as the basement membrane. A finger-like projection, or fold, known as the dermal papilla (plural.

The Skin Model concept is the basic concept of GeoSpelling. It is an abstract model of the physical interface between a workpiece and its environment. Different from the nominal model, which is deemed as an ideal feature, the Skin Model is a shape model to describe the non-perfect shapes.

The skin is by far the largest organ of the human body, weighing about 10 pounds (4.5 kg) and measuring about 20 square feet (2 square meters) in surface area. It forms the outer covering for the entire body and protects the internal tissues from the external environment. The skin consists of two distinct layers: the epidermis and the dermis.
