10 Acne Inversa Myths That Need to Go

Written by Dr. rer. nat. Dennis Alexander Kwiatkowski

Living with acne inversa — also known as hidradenitis suppurativa (HS) — is already difficult enough. Living with it while surrounded by misinformation makes it harder. Myths about acne inversa are everywhere: in casual conversations, on social media, sometimes even in medical waiting rooms. They can delay diagnosis, cause unnecessary shame, and lead people to avoid the help they need.

This article addresses ten of the most persistent myths about acne inversa and looks at what the medical evidence actually tells us.

Myth 1: Acne inversa is caused by poor hygiene

This is probably the most damaging misconception about HS. It is not caused by being unclean, and no amount of washing will prevent it. Acne inversa is a chronic inflammatory skin condition rooted in immune system dysregulation, follicular occlusion, and genetic predisposition.

The lesions that develop in skin folds — the axillae, groin, under the breasts, or on the inner thighs — happen to occur in areas that are warm and moist, which may reinforce the false impression that hygiene is involved. But the underlying pathology has nothing to do with cleanliness.

Gentle skin care matters for comfort and infection prevention, but HS is not a hygiene problem. Framing it as one places blame on the patient and discourages people from seeking medical attention.

Myth 2: It is just acne

The name itself can be misleading. “Acne inversa” shares a word with acne vulgaris, the common form of acne most people know. But despite some superficial similarities — both involve the hair follicle — these are fundamentally different conditions.

Acne vulgaris is driven largely by sebum production and Cutibacterium acnes and typically appears on the face, chest, and upper back. Acne inversa, by contrast, involves recurrent deep-seated nodules, abscesses, and sinus tracts in the intertriginous areas. The pathophysiology, treatment approach, and long-term course are distinct. Standard acne treatments such as benzoyl peroxide washes or topical retinoids are not effective against HS.

Getting this distinction right matters — for patients, for clinicians, and for anyone trying to understand what someone with HS is going through. For a side-by-side breakdown, see our complete clinical comparison of HS and acne vulgaris.

Myth 3: Only overweight people get acne inversa

Obesity is a recognized risk factor for HS. It can worsen symptoms through increased friction, heat retention, and hormonal influences. But it is not a cause, and acne inversa affects people across a wide range of body types.

HS has been documented in lean individuals, adolescents, and people with no metabolic comorbidities. Studies estimate that up to one-third of HS patients are of normal weight. The disease has a strong genetic component — up to 40% of patients report a family history of HS — and the immune-inflammatory mechanisms at its core are not dependent on body weight.

Focusing exclusively on weight can delay proper treatment and contribute to stigma. HS management should address the disease itself, not reduce it to a lifestyle issue.

Myth 4: Acne inversa is contagious

It is not. Acne inversa cannot be transmitted from person to person through physical contact, shared clothing, or any other route. It is an inflammatory condition, not an infectious disease.

Secondary bacterial infections of existing lesions can occur, and drainage from abscesses may contain bacteria. But the disease process itself is immune-mediated. You cannot catch HS from someone who has it. We cover this in more detail in our dedicated article on whether acne inversa is contagious.

This myth has real consequences. It can lead to social isolation, shame, and reluctance to seek medical care or to be physically close to others. It needs to be addressed clearly and directly.

Myth 5: Acne inversa can be cured

As of today, there is no known cure for acne inversa. It is a chronic, relapsing condition. Treatment goals focus on reducing inflammation, managing flares, preventing disease progression, limiting complications such as scarring and sinus tract formation, and improving quality of life.

A range of treatment options exists — from topical and systemic antibiotics to biologic therapies and surgical interventions — and many patients can achieve meaningful improvement. Some patients experience periods of relative remission, especially with consistent treatment and disease management. But claiming that any product, diet, or protocol can cure HS is misleading and potentially harmful.

Be wary of any source — online or otherwise — that promises a cure. Responsible disease management is a more realistic and more honest framework.

Myth 6: It is a rare condition that most doctors know well

This is actually two myths rolled into one.

First, acne inversa is more common than many people assume. Prevalence estimates vary, but recent studies suggest figures in the range of 0.1% to as high as 1–4% of the population in some European and North American cohorts, depending on the methodology used. It is not an ultra-rare disease.

Second — and somewhat paradoxically — awareness among healthcare professionals is still inconsistent. The average diagnostic delay for HS has been reported at approximately 7 to 10 years in multiple studies. Patients are often initially misdiagnosed with boils, folliculitis, or recurrent skin infections before receiving the correct diagnosis. This delay can have serious consequences for disease progression — which is why recognizing HS early is so important.

If you suspect you may have HS, seeking a dermatologist with experience in the condition is an important step.

Myth 7: Diet causes acne inversa

Diet does not cause acne inversa. The disease has genetic, immunological, and hormonal drivers that exist independently of what someone eats.

That said, some patients report that certain dietary factors seem to influence their flare patterns. Dairy products and brewer’s yeast are among the most frequently mentioned triggers in patient-reported surveys, and a small number of studies have explored elimination diets in HS cohorts. But the evidence base is still limited, and dietary changes alone are not a substitute for medical treatment.

The distinction between “can influence symptoms in some people” and “causes the disease” matters. Attributing HS to diet risks blaming patients for their condition and oversimplifying a complex disease.

Myth 8: Surgery will fix it permanently

Surgery plays an important role in HS management — particularly wide excision of chronically affected areas, deroofing of sinus tracts, and incision and drainage for acute abscesses. In carefully selected patients and disease stages, surgical approaches can provide significant and lasting improvement.

However, surgery does not address the underlying inflammatory process. Recurrence in previously unaffected areas is possible, because the systemic immune dysregulation that drives the disease remains. This is why current treatment guidelines increasingly emphasize combining surgical intervention with medical therapy — including biologics where appropriate — rather than relying on surgery alone.

Understanding this can help set realistic expectations and support better treatment planning.

Myth 9: Acne inversa only affects women

HS affects both men and women. Some earlier epidemiological studies reported a female predominance, with female-to-male ratios around 3:1, but more recent data suggests the gap may be narrower than previously thought.

What does differ between sexes is the typical distribution pattern. Women more commonly experience HS in the groin and axillary regions, while men are more frequently affected in the perianal and gluteal areas. Hormonal factors — particularly androgens and fluctuations related to the menstrual cycle — appear to play a role in disease activity in some female patients, but the full picture is still being studied.

The key point is that HS does not discriminate by sex, and men experiencing recurrent nodules or abscesses in skin-fold areas should be evaluated for HS just as seriously as women.

Myth 10: There is no point in seeing a doctor — nothing really helps

This may be the most dangerous myth of all.

It is true that HS can be difficult to treat, and that many patients have had frustrating experiences with healthcare providers who were unfamiliar with the condition. But the treatment landscape for HS has changed significantly in recent years. Biologic therapies — including adalimumab, which was the first biologic approved specifically for HS, and secukinumab, which received approval more recently — have demonstrated efficacy in clinical trials. Combination approaches involving antibiotics, anti-inflammatory agents, lifestyle modifications, wound care, and surgery continue to evolve.

Beyond pharmacological options, structured disease management, pain management, and psychological support can all make a meaningful difference in quality of life. If you are preparing for an appointment, our list of 15 questions to ask your dermatologist can help you make the most of the visit.

Giving up is not the answer. Finding the right doctor — ideally a dermatologist experienced with HS — and building a treatment plan that addresses the disease from multiple angles is worth pursuing.

Key Takeaways

Acne inversa is a chronic, immune-mediated inflammatory condition. It is not caused by poor hygiene, not contagious, not just acne, and not limited to any single body type, sex, or dietary pattern. There is currently no cure, but there are effective treatments — and the field is advancing.

Myths about HS cause real harm. They delay diagnosis, increase shame, and discourage people from seeking help. The more accurately we talk about this condition, the better the outcomes — for patients, for clinicians, and for everyone working to improve awareness.

If you think you or someone you know may have acne inversa, speak with a dermatologist. Early and proactive management can make a difference.
