What is the Origin of Testosterone Dermal Support?

Testosterone is the principal male sex hormone, and dermal support describes its positive trophic effects on skin structures. This concept originates from the differential androgen sensitivity observed across various skin regions and appendages. The influence is mediated via the androgen receptor present in dermal and follicular cells.

What is the Mechanism of Testosterone Dermal Support?

Testosterone binds to the androgen receptor in target dermal cells, initiating gene expression that promotes sebocyte differentiation and proliferation, increasing sebum output. Furthermore, androgens can exert anabolic effects on dermal fibroblasts, influencing the synthesis and organization of collagen and ground substance components. This signaling helps maintain skin thickness and barrier function in androgen-responsive areas.

Testosterone Dermal Support

Meaning

The physiological contribution of androgens, primarily testosterone and its potent metabolite DHT, to the maintenance and function of the skin, particularly concerning sebaceous gland activity and hair follicle cycling. This support is critical for achieving mature skin characteristics, including sebaceous oil production and dermal structural support. Clinical relevance lies in understanding the effects of androgen modulation on cutaneous health.
