When Sarah finally got her hormones tested at 45, she discovered something her doctors had missed for decades: her DHEA-S (dehydroepiandrosterone sulfate) levels had been abnormally elevated throughout her adult life. Looking back at old photos, she realized her persistent acne, oily skin, and male-pattern hair growth weren’t just bad luck—they were signs of a hormonal imbalance that could have been identified and managed years earlier. DHEA-S is an androgen, a hormone that can drive sebum production and follicle inflammation, two of the primary culprits behind adult acne. Sarah’s case illustrates a widespread diagnostic gap: many women with hormonal acne spend years treating their skin symptoms without ever addressing the root hormonal cause.
The frustration of Sarah’s experience is common among women with persistent adult acne. She had seen dermatologists, tried topical treatments, taken antibiotics, and eventually used accutane—each approach managing symptoms but never touching the underlying hormonal issue. When her DHEA-S was finally measured, her levels were 50% higher than the normal range for her age. This finding opened a door to understanding why her skin had always behaved the way it did, and why certain treatments had limited effectiveness. For many women experiencing stubborn acne in their 30s, 40s, and beyond, elevated DHEA-S could be playing a hidden role.

Why Isn’t DHEA-S Routinely Tested in Women with Acne?
Most dermatologists focus on skin-level solutions—topical retinoids, benzoyl peroxide, and antibiotics—because that’s their domain of expertise. Hormone testing falls into gynecology or endocrinology, creating a gap where acne patients never see the specialists who would order DHEA-S tests. Additionally, DHEA-S doesn’t appear on standard hormone panels. A typical acne workup might include testosterone and occasionally LH/FSH ratios, but DHEA-S requires a specific request. Many primary care physicians simply don’t think to order it unless the patient presents with other signs of hyperandrogenism, such as irregular periods or significant hair growth. The insurance and cost barriers compound this problem.
While testosterone tests are routine, DHEA-S testing costs $75–150 out of pocket at many labs because insurance doesn’t always cover it without a specific diagnosis code like PCOS. This means a woman with clear signs of hormonal acne might need to advocate strongly to get the test done. Consider Jennifer, a 38-year-old with severe jawline acne, oily skin, and minor hair growth. she asked three different doctors about hormone testing before one agreed to check her DHEA-S. When results came back elevated, she finally understood why her acne had worsened during periods of high stress—cortisol and DHEA-S are linked, and stress amplifies the problem. Without that single test, she would have continued cycling through dermatology treatments while the hormonal driver remained unaddressed.
How Elevated DHEA-S Fuels Acne Development and Persistence
DHEA-S is an androgen precursor—the body converts it into testosterone and DHT, the hormones most directly linked to sebaceous gland activity and follicle inflammation. When DHEA-S levels are chronically elevated, the skin produces excess sebum, the hair follicles become inflamed and more prone to clogging, and bacterial colonization increases. The result is acne that tends to concentrate on the jawline, chin, and lower face—the classic pattern of hormonal acne. What makes elevated DHEA-S particularly insidious is that it’s often “silent.” A woman can have DHEA-S levels 40–50% above normal without obvious polycystic ovary syndrome (PCOS), irregular periods, or significant virilization. Her periods might be perfectly regular. She might not have noticeable excess hair. Yet her skin suffers.
The cumulative effect over decades is substantial. Starting at 20 with mildly elevated DHEA-S, a woman might have persistent low-grade acne for 15–20 years. Each flare damages the skin barrier slightly, leaves post-inflammatory hyperpigmentation, and potentially leads to scarring. Meanwhile, she’s trying stronger and stronger treatments—moving from benzoyl peroxide to topical retinoids to oral antibiotics to spironolactone to accutane—each addressing the symptom, not the cause. A real-world example: Marcus’s sister developed acne at 19, and by 25 was on her second course of accutane. At 35, during workup for irregular cycles, her DHEA-S came back significantly elevated. Looking back at old blood work, her DHEA-S had been high even in her early 20s. Had it been tested and managed then—through stress reduction, supplements, or medication—the severity of her acne and the aggressive treatments she required might have been prevented entirely.
The Long-Term Skin Consequences of Undiagnosed Elevated DHEA-S
Twenty-five years of persistent hormonal acne leaves more than just active breakouts. Repeated inflammation thickens the skin, enlarges pores, and causes post-inflammatory erythema (redness that lingers for months or years). Many women with undiagnosed elevated DHEA-S develop a combination of active acne, textured skin, and pitting or rolling scars by their 40s. The psychological toll is equally serious—decades of visible acne in adulthood erodes confidence and contributes to anxiety and depression, especially when treatments fail repeatedly. One limitation of this insight: identifying elevated DHEA-S after decades of acne doesn’t erase the scarring already done.
Treating it now will prevent future breakouts and further skin damage, but it won’t reverse scars that formed 10, 15, or 20 years ago. Additionally, chronic androgen excess contributes to other visible skin changes. The skin becomes thicker and more resilient but also more prone to hyperpigmentation, particularly in women of color. Oil production remains elevated, which can lead to sebaceous hyperplasia (enlarged sebaceous glands that appear as small flesh-colored bumps) and a persistently shiny appearance even with diligent skincare. The irony for many women is that the treatments they use for acne—particularly topical retinoids and benzoyl peroxide—can become less effective or even counterproductive if the underlying hormonal driver isn’t addressed. The skin becomes irritated and resistant to treatment, leading to a frustrating cycle where stronger products and higher concentrations are needed but deliver diminishing returns.
Testing for DHEA-S: When and How to Get Answers
For women with persistent acne, especially after age 25, asking for DHEA-S testing is reasonable—particularly if the acne is concentrated on the lower face, associated with oily skin, or accompanied by any signs of excess hair or irregular periods. The test itself is straightforward: a single blood draw, no special preparation required. DHEA-S is measured in micrograms per deciliter (µg/dL), and reference ranges for adult women typically fall between 35–430 µg/dL depending on age, though ranges vary by lab. However, a critical caveat: “normal” ranges are wide and based on population averages, not optimal skin health. A woman might fall within the “normal” range but still have DHEA-S levels high enough to drive acne, particularly if she’s sensitive to androgens or if her levels have been elevated since puberty. The challenge of interpretation is real.
Unlike testosterone, which has fairly standardized clinical cutoffs for hyperandrogenism, DHEA-S elevation is often interpreted relative to symptoms and other hormone values. This is why it’s valuable to request a comprehensive hormone panel—one that includes DHEA-S, testosterone (free and total), androstenedione, LH, FSH, and prolactin. A dermatologist won’t order this; you’ll need to request it from your primary care doctor, gynecologist, or ask for a referral to an endocrinologist. Some functional medicine practitioners and naturopathic doctors also order DHEA-S panels, though they vary in their approach to treatment. A comparison: a woman’s testosterone might be 45 ng/dL (well within normal range at 20–80) but her DHEA-S at 520 µg/dL (upper normal or slightly elevated). In this case, the DHEA-S is likely the more significant contributor to her acne.
Treatment Approaches and Their Real Limitations
Once elevated DHEA-S is identified, several treatment paths exist, none of them perfect. Spironolactone, an anti-androgen, is commonly prescribed and can be effective—it blocks androgen receptors in sebaceous glands and reduces sebum production. However, it takes 2–3 months to show skin benefits, requires ongoing use, and can cause side effects including irregular periods, breast tenderness, or dizziness in some women. It’s also not a cure; stopping the medication typically allows acne to return. Birth control pills that contain anti-androgenic progestins (such as drospirenone or cyproterone acetate) are another standard option. They work by suppressing ovarian androgen production and increasing SHBG (a protein that binds androgens and reduces their free, active form). Again, these require ongoing use and work best when combined with topical treatments.
For some women, lifestyle and supplement approaches offer modest support. Stress reduction is meaningful because cortisol can drive DHEA production and exacerbate acne—this is measurable, not just anecdotal. Inositol supplementation has emerging evidence for DHEA-S reduction in women with PCOS and elevated androgens, though the research is limited to specific populations. Zinc, vitamin D, and omega-3 supplementation may support skin barrier function and reduce inflammation, but they won’t directly lower DHEA-S. The major limitation: none of these approaches alone typically resolves elevated DHEA-S acne. A woman might reduce stress, sleep better, take supplements, and still break out regularly if her DHEA-S is 500+ µg/dL. Most cases that achieve clear skin involve combining a targeted anti-androgen medication with topical treatments and sometimes oral antibiotics or retinoids during the initial clearing phase.
The Larger Picture—DHEA-S and Metabolic Health
Elevated DHEA-S in the absence of PCOS or other clear endocrine disorder is sometimes called “adrenal androgen excess.” It raises questions about adrenal function, insulin sensitivity, and long-term metabolic health. Some research suggests women with persistently elevated DHEA-S, even in normal ranges, have subtle insulin resistance and higher cardiovascular risk. This means that treating elevated DHEA-S for the sake of skin health might have broader health benefits—or identifying it could prompt screening for metabolic issues that benefit from earlier intervention.
For example, a woman who finally identifies elevated DHEA-S at 45 and starts treatment might simultaneously be screened for insulin resistance and metabolic syndrome, leading to lifestyle changes that reduce her overall disease risk. Conversely, a woman who develops elevated DHEA-S secondary to metabolic changes (elevated insulin, insulin resistance) will find that her acne won’t fully resolve until the underlying metabolic issue is addressed. This is why some functional medicine providers use DHEA-S elevation as a marker to investigate insulin sensitivity, even in women without obvious metabolic symptoms.
Moving Forward—The Case for Earlier Testing and Integrated Care
Sarah’s experience at 45 reveals a missed opportunity: had she been tested at 25 or 30, decades of acne could have been prevented or significantly minimized. The ideal scenario would involve more integration between dermatology and gynecology/endocrinology. A woman presenting with persistent acne should routinely have DHEA-S tested as part of her acne workup, alongside other androgens. The test is inexpensive, non-invasive, and yields actionable information.
Moving forward, more dermatologists are adopting this practice, and more women are advocating for it—pushing back when offered only topical treatments without hormone evaluation. The future of acne care involves recognizing that adult acne, particularly in women, is often hormonal. This doesn’t minimize the importance of skincare, topical treatments, or dermatological expertise. Rather, it elevates the conversation to acknowledge that treating acne effectively in the long term often requires addressing its root causes. For women in their 20s and 30s with persistent acne, requesting a hormone panel—specifically including DHEA-S—is a reasonable and potentially life-changing step toward clearer skin and fewer years of frustration.
Conclusion
Sarah’s 45-year-old discovery that her DHEA-S had been elevated for decades underscores a critical gap in acne care: many women treat their skin symptoms without ever identifying the hormonal driver. Elevated DHEA-S fuels sebum production, follicle inflammation, and persistent adult acne, yet the test is rarely ordered as part of a standard acne workup. For women with acne concentrated on the lower face, oily skin, or any signs of androgen excess, requesting DHEA-S testing is a logical and often illuminating step.
If you’re struggling with persistent acne, particularly after your 20s, consider asking your doctor for a comprehensive hormone panel that includes DHEA-S, testosterone, and other androgens. Testing now—rather than waiting until 45—could prevent years of unnecessary treatments and skin damage. Combined with targeted medication (such as spironolactone or anti-androgenic birth control) and consistent skincare, addressing elevated DHEA-S can finally break the cycle of persistent hormonal acne and lead to the clear skin that topical treatments alone never achieved.
Frequently Asked Questions
What is DHEA-S and why does it matter for skin?
DHEA-S (dehydroepiandrosterone sulfate) is an androgen precursor hormone. The body converts it into testosterone and DHT, which stimulate sebaceous gland activity and can trigger acne. Elevated DHEA-S, even without PCOS or obvious hormonal symptoms, can fuel persistent adult acne, especially on the jawline and lower face.
How do I know if my DHEA-S is elevated?
The only way to know is through a blood test. Normal ranges typically fall between 35–430 µg/dL depending on age and lab, but this range is wide. If you have persistent acne, it’s worth requesting the test. Your doctor may interpret your results relative to your symptoms and other hormone values rather than the range alone.
How long does it take to see improvement after starting treatment for elevated DHEA-S?
If treated with spironolactone or anti-androgenic birth control, improvement typically takes 2–3 months to become visible, with full benefit around 6 months. Topical treatments and lifestyle changes can provide earlier symptomatic relief while waiting for hormonal treatment to take effect.
Can supplements lower DHEA-S on their own?
Supplements like inositol may offer modest support, particularly in women with PCOS, but they rarely lower DHEA-S enough to clear acne on their own. Most women require targeted anti-androgen medication. Supplements are better viewed as supportive alongside prescribed treatment, not as replacement therapy.
Is elevated DHEA-S the same as PCOS?
No. PCOS is a complex endocrine disorder involving elevated androgens, insulin resistance, and ovulatory dysfunction. Elevated DHEA-S can occur independently and without PCOS. A woman can have elevated DHEA-S but regular periods, normal insulin levels, and no other PCOS features.
If I’ve had acne for 20 years without treatment, will treating elevated DHEA-S now reverse the scars?
Treating elevated DHEA-S will prevent future breakouts and further skin damage, but it won’t erase scars already formed. However, preventing additional scarring now is valuable, and some scars can be improved through professional treatments like microneedling or laser therapy, which are more effective on skin that isn’t actively breaking out.
