Abstract: Disclosed herein is the use of a non-natural compound represented by the following formula 1 as an activator of the peroxisome proliferator activated receptor-? (PPAR-?) which shows an anti-inflammatory effect on inflammatory skin diseases. The PPAR-? activator increases the expression of PPAR-? in the skin to enhance various physiological effects of PPAR-?, that is, the anti-inflammatory effect caused by inhibiting the activity of transcription factors such as the nuclear factor ?K (NF-?K) that induces inflammatory reactions, the effect of improving the epidermal permeability barrier function of the skin, and the effect of promoting the terminal differentiation of epidermal keratinocytes. Thus, the PPAR-? activator is useful for the treatment, alleviation or amelioration of skin diseases such as acne, seborrheic dermatitis, viral skin diseases, urticaria, pruritus, viral infectious diseases and contact dermatitis.
