Stress Hormones Beyond Cortisol: What Adrenaline and DHEA Do to Your Skin

Cortisol gets all the attention in stress-and-skin conversations, and for good reason, it's the hormone most consistently linked to breakouts, dullness, and slower healing. But cortisol doesn't work alone. Two other hormones released during a stress response, adrenaline (also called epinephrine) and DHEA (dehydroepiandrosterone), play distinct roles in what stress does to your skin, and they get lumped in with cortisol far more often than the science actually supports.

Adrenaline is the fast responder. It's released by the adrenal medulla within seconds of a perceived threat, as part of the sympathetic nervous system's "fight or flight" activation, and it's largely gone again within minutes once the trigger passes. Its job is to redirect blood flow toward muscles and away from less urgent systems, including the skin, which is why sudden stress or fear can make someone visibly pale, and why the adrenaline surge of embarrassment or exertion can just as easily flush the face once blood vessels dilate again. Cortisol, by contrast, is the slow-burn hormone: it's produced by the adrenal cortex, takes longer to rise and fall, and lingers in the system during chronic stress in a way adrenaline does not.

DHEA is a different kind of stress hormone altogether. It's produced alongside cortisol in the adrenal cortex, but it functions as a precursor, a raw material the body converts in small amounts into testosterone and estrogen. DHEA has been associated with collagen production, skin hydration, and sebum (oil) output, which is part of why researchers have taken an interest in it as skin ages. Unlike cortisol, which spikes with stress, DHEA follows its own separate trajectory: levels peak in early adulthood and decline steadily with age, a pattern sometimes called "adrenopause."

Here's what's actually been demonstrated. A 2024 clinical study examining chronic moderate psychological stress found it was associated with measurable reductions in skin's antioxidant capacity along with changes to the skin barrier and surface microrelief, evidence that sustained stress leaves a physical signature on skin, not just a subjective one. On the DHEA side, one small, 12-month, placebo-controlled trial in postmenopausal women given 50 milligrams of DHEA daily found less skin thinning and better hydration compared with placebo. That's a genuinely interesting result, but it's a single small trial in one population (postmenopausal women), using a specific dose, and it doesn't establish that DHEA supplementation broadly improves skin for everyone.

Where things get shakier is the supplement aisle. Over-the-counter DHEA products are marketed heavily for anti-aging and skin benefits, but Mayo Clinic and Harvard Health both describe the overall evidence base as weak, inconsistent across studies, or limited to small trials like the one above. Supplement quality control is also a real concern, DHEA products aren't regulated with the same rigor as medications, so actual dosage can vary from what's printed on the label. And because DHEA converts into sex hormones, Mayo Clinic notes long-term or high-dose use carries theoretical risks around hormone-sensitive cancers that haven't been ruled out. As for adrenaline, there's no legitimate skincare or wellness product that meaningfully "targets" it, its effects are too fast and too tied to acute nervous-system activity for any topical or ingestible product to plausibly modulate for skin benefit.

None of this means the hormones themselves aren't worth understanding, quite the opposite. Knowing that adrenaline acts in seconds while DHEA follows a decades-long decline makes it a lot easier to spot when a wellness claim is oversimplifying the science, or borrowing credibility from one hormone to sell a product aimed at another. If you're curious about DHEA supplementation specifically, that's a conversation to have with a doctor, not a decision to make based on a product label, particularly given the unresolved questions around long-term safety.
