Acne vulgaris is often seen as a rite of passage through the teen years — but what happens when those breakouts follow you into your 30s or even 40s? You’re not alone. Adult acne is a growing concern, especially among women, and it’s rarely talked about in the right context. As a naturopathic doctor with a special interest in skin, hormonal health, and stress regulation, I want to spotlight what is really going on beneath the surface — and why acne is not just skin deep.

Acne in adulthood tends to show up slightly differently than when we first see it in the adolescence years — think jawline breakouts, chin cysts, and stubborn clogged pores that linger for weeks. This form of acne is often more than just oily skin and clogged hair follicles. It reflects deeper internal imbalances — particularly involving gut health, hormones and chronic stress patterns.

Figure 1: It really does start with a clogged pore

When dead skin cells and excess sebum (oil) accumulate inside a hair follicle, they create a plug. This plug traps oil beneath the skin’s surface. If your sebaceous (oil) glands are producing too much oil — often influenced by hormones — the buildup begins. This is the starting point of many blackheads and whiteheads.

Figure 2: Bacteria multiplies

Once a pore is clogged, it creates the perfect environment for Cutibacterium acnes (c. acnes) — the acne-causing bacteria — to thrive. These bacteria feed on the trapped oil, multiply, and trigger the inflammatory cascade. This is where acne moves beyond a basic clogged pore and becomes a deeper, inflamed lesion.

Figure 3: Your immune system steps into the party

The body recognizes this inflammation and responds by sending immune cells to the area. The result? Redness, swelling, and often pus (dead skin & immune cells) — all signs of your immune system trying to fight the infection. This immune response is what causes those painful, inflamed pimples many people struggle with in adult acne.

The Hormonal Connection

In adult women, acne is frequently tied to hormonal fluctuations. These can be influenced by:

Hormonal birth control (the pill, IUD, patch etc)
Irregular menstrual cycles, PCOS, endometriosis
Perimenopause, menopause, pregnancy and/or estrogen/progesterone imbalances
Blood sugar and insulin spikes

When androgen hormones (like testosterone and DHEA-S) are elevated — even slightly — they can increase oil production, thicken the skin lining of pores, and drive inflammatory acne, more specifically along the chin, jawline and neck. But it’s not always about lab values being "out of range" — sometimes, it's the sensitivity of your skin to these hormones that matters most.

When we think of hormonal birth control, it's often associated with clearer skin — and in some cases, that’s true. Certain contraceptives, particularly combination oral contraceptives (with both estrogen and progestin), can reduce androgens and suppress sebum production. However, emerging research highlights a lesser-known reality: not all hormonal contraception is acne-friendly, and some forms may actually contribute to breakouts, especially in adults.

Progestin-only contraceptives, including the hormonal IUD (such as Mirena, Kyleena, or Skyla) and certain progestin-dominant oral contraceptives, have been linked to an increase in acne symptoms. These contraceptives can stimulate androgen receptors in the skin, leading to excess oil production, clogged pores, and inflammation. In fact, studies suggest that up to 35% of hormonal IUD users may experience acne flare-ups, particularly within the first year after insertion. While this reaction doesn’t affect everyone, it's an important consideration for individuals managing persistent or unexplained acne in adulthood.

Compounding this, many people experience a resurgence of acne after stopping hormonal birth control — typically within 3 to 6 months. Often referred to as post-pill acne, this flare reflects the body’s attempt to reestablish its natural hormonal rhythm. During this time, androgens like testosterone may temporarily dominate, increasing sebum production and triggering breakouts. But the skin's response also points to deeper physiological imbalances that may have been masked by years of hormonal suppression — such as gut dysbiosis, impaired liver detoxification, and micronutrient depletion (notably zinc, B vitamins, and magnesium). Rather than viewing these acne flares as isolated skin issues, they can be powerful clinical clue that the body’s internal systems — particularly hormone metabolism, stress response, and detoxification — need extra support. Understanding this connection allows for a more targeted, root-cause approach to adult acne care.

The Stress-Skin Axis

Cortisol, the body’s primary stress hormone, plays a central role in the connection between chronic stress and acne — especially in adults. In response to perceived stress, the hypothalamic-pituitary-adrenal (HPA) axis is activated, leading to the release of cortisol from the adrenal glands. While short bursts of cortisol help the body adapt, chronic elevation — as seen in prolonged mental, emotional, or physiological stress — has far-reaching consequences for skin health.

As we age, our ability to regulate cortisol becomes less efficient. Cortisol impacts the skin through several mechanisms:

Suppresses the immune system, impairing the skin’s ability to defend against bacteria such as C. acnes.
Promotes systemic inflammation, which can exacerbate inflammatory acne lesions and delay healing.
Raises blood glucose levels via gluconeogenesis, which stimulates insulin and insulin-like growth factor 1 (IGF-1). Elevated IGF-1 levels enhance sebaceous gland activity and keratinocyte proliferation, both of which contribute to acne development.

In addition, cortisol disrupts melatonin production and contributes to poor sleep quality — reducing the time your skin has to repair damage, clear post-inflammatory pigmentation, and restore barrier function. Stress also affects the gut-brain-skin axis, a bidirectional communication system between the nervous system, gastrointestinal tract, and skin. Cortisol can alter gut motility, permeability (aka “leaky gut”), and microbial balance, contributing to systemic inflammation and hormonal imbalance — both of which can present on the skin as acne, rosacea, or increased skin sensitivity. So when stress is ongoing, your skin isn’t just reacting on the surface — it’s reflecting so much more beneath the surface.

The Naturopathic Approach to Adult Acne

Instead of chasing symptoms with harsh topicals or antibiotics alone, I work with patients to:

Test and assess hormonal imbalances, including cortisol, androgens, insulin, nutrient deficiencies and gut health (microbiome, food sensitivities)
Support the body’s detox pathways through the liver, gut, kidney's and lymphatic system
Balance blood sugar regulation through nutrient-rich, anti-inflammatory meals
Regulate stress with herbal adaptogens, acupuncture, breath-work, and effective sleep hygiene
Use evidence-informed skincare with ingredients like azelaic acid, niacinamide, retinoids, sunscreen and gentle exfoliants tailored to what your skin needs
Utilizing red light therapy and other professional treatments (IPL, microneedling, high frequency, chemincal peels)

With June being Acne Awareness Month — Let’s Reframe the Narrative

Acne in adulthood doesn’t mean you're doing something wrong — it’s your body’s way of communicating an internal imbalance. It’s an interplay of internal and external factors — from hormones and oil production to bacteria and inflammation. Supporting skin health means working from the inside out: balancing hormones, managing stress, calming inflammation, and improving detox and digestive function.

Instead of covering up, I encourage you to get curious. What is your skin trying to tell you?

If this speaks to you, I’d love to help you uncover the root cause and build a skin plan that works for you. Let’s decode your skin symptoms and start your journey to clear, calm, confident skin.
