Impact of skin sensitivity mechanisms on sebum secretion: Management strategies for oily sensitive skin

Recent epidemiological surveys based on Baumann's classification have revealed a notable rise in the prevalence of oily sensitive skin. The development of oily sensitive skin is primarily linked to the abnormal function of sebaceous glands. The function of sebaceous glands is regulated by several factors, including inflammatory mediators, neurotransmitters, and endocrine signals. Sensitive skin, particularly oily sensitive skin, is prone to local inflammation, which in turn disrupts the normal functioning of sebaceous glands. This creates a loop wherein increased oil production exacerbates sensitivity, while heightened sensitivity further stimulates sebum secretion, perpetuating a vicious cycle. This article summarizes our understanding of the four primary mechanisms underlying skin sensitivity and their impact on sebaceous gland activity. Accordingly, it proposes management strategies for oily sensitive skin and seeks to guide the development of skin care regimens for this skin type
