Thin skin is defined by the thickness of the epidermis, which is the outermost layer of the skin. Typically, thin skin has a thinner stratum corneum and may lack certain features like hair follicles or sebaceous glands, making it more delicate and sensitive. It is commonly found in areas of the body such as the eyelids and beneath the armpits, where flexibility and sensitivity are crucial. This thinner structure can make it more susceptible to damage and aging.
