Bioinformatics is a research field that uses computer‐based tools to investigate life sciences questions employing “big data” results from large‐scale DNA sequencing, whole genomes, transcriptomes, metabolomes, populations, and biological systems, which can only be comprehensively viewed in silico. The epidermis was among the earliest targets of bioinformatics studies because it represents one of the most accessible targets for research. An additional advantage of working with the epidermis is that the sample can even be recovered using tape stripping, an easy, noninvasive protocol. Consequently, bioinformatics methods in the fields of skin biology and dermatology generated a fairly large volume of bioinformatics data, which led us to originate the term “skinomics.” Skinomics data are directed toward epidermal differentiation, malignancies, inflammation, allergens, and irritants, the effects of ultraviolet (UV) light, wound healing, the microbiome, stem cells, etc. Cultures of cutaneous cell types, keratinocytes, fibroblasts, melanocytes, etc., as well as skin from human volunteers and from animal models, have been extensively experimented on. Here, we review the development of the skinomics, its methodology, current achievements, and future potentials.
