Androgens and the Skin: Tissue Sensitivity Matters More Than Testosterone Levels

Androgens play a central role in multiple dermatologic conditions, yet elevated serum testosterone is surprisingly uncommon in many affected patients. Acne, seborrhea, hirsutism, and androgenic alopecia often reflect increased androgen sensitivity at the tissue level rather than systemic hormone excess.

Understanding androgen dynamics requires shifting focus from serum concentration to local metabolism.

Sources of Androgens in Women

Androgens in women originate from multiple sites:

• Adrenal glands
• Ovaries
• Peripheral tissue conversion¹

Notably, 100 percent of dihydrotestosterone is produced in peripheral tissues via 5-alpha reductase activity². This makes skin, hair follicles, and sebaceous glands active participants in androgen signaling.

DHEA and Dermatologic Disease

Dehydroepiandrosterone is one of the most abundant circulating steroid hormones and serves as a precursor for both androgens and estrogens³. While often marketed as a benign “anti-aging” supplement, DHEA supplementation can exacerbate acne, hirsutism, and androgenic hair loss, particularly in patients with heightened peripheral conversion.

Clinically, elevated DHEA sulfate may signal:

• Chronic stress physiology
• Adrenal-driven androgen excess
• Increased substrate availability for androgen conversion

Why Normal Testosterone Does Not Exclude Androgen-Driven Disease

Several factors amplify androgen signaling without raising serum testosterone:

• Increased 5-alpha reductase activity
• Enhanced androgen receptor expression
• Insulin-mediated amplification of androgen signaling⁴

This explains why insulin resistance and high glycemic diets often worsen androgen-mediated skin disease despite normal laboratory values.

Clinical Relevance

For dermatology providers, this framework clarifies why:

• Androgen blockade may help even with normal testosterone
• Addressing insulin resistance improves acne outcomes
• DHEA supplementation frequently backfires in skin patients

Understanding androgen metabolism allows for targeted intervention rather than trial-and-error suppression.
