RESUMO
Skin, the largest vital organ of the human body, provides the first line of defense against biological, non-biological and xenobiotics exposure. Over the years, due to increased anthropogenic activities including industrialization and pollution, a steep increase in cutaneous pathological conditions such as malignancies, dermatitis, and psoriasis has been detected. Indeed, due to the complex nature of cutaneous inflammatory diseases, further investigations are required to produce a better outcome in patient care. However, research obtained over the last few decades has revolutionized the understanding of cutaneous disease pathogenesis and therapeutic developments. In this line, increasing data from pre-clinical and clinical studies implicates the crucial role of oxidative stress in pathogenesis and complications of cutaneous inflammatory diseases, including atopic dermatitis and psoriasis. Taking into consideration the current challenge, this review aims to highlight the novel updates exploring reactive oxygen species (ROS) induced mechanistic signaling mechanisms in conjunction with pathways converging towards atopic dermatitis and psoriasis. Additionally, an exploration of the clinical importance of natural products for management of cutaneous diseases has been included. Overall, this review highlights the therapeutic importance of targeting oxidative stress in the pathogenesis, symptoms, and complications of inflammatory diseases of the skin.
