Skin Thickness

Meaning

Skin thickness refers to the measurable depth of the dermal and epidermal layers, a critical physiological parameter that is directly influenced by the body’s systemic hormonal status and cellular vitality. Optimal skin thickness is clinically indicative of robust collagen and elastin production, which is heavily supported by key anabolic hormones such as estrogen, testosterone, and growth hormone. The progressive decline in skin thickness is a well-established, quantifiable biomarker of tissue aging and hormonal senescence, often correlating with overall physiological decline.
