Acne in Your 20s, 30s & 40s: Why It's Still Happening and What Actually Works

If you thought acne was something you'd leave behind in your teenage years, you're far from alone in being surprised to still be dealing with it as an adult. Adult acne is extremely common, and it often behaves differently — and responds to different treatments — than the breakouts of adolescence. At Le Beauty & Skincare in Brisbane, adult acne is one of the most frequent concerns we see in clinic, and one we take seriously.

Here's what you need to know.

Why Adult Acne Is Different from Teenage Acne

Teenage acne is primarily driven by a surge in androgens during puberty, which increases sebum production and leads to widespread breakouts — often across the forehead, nose, and cheeks. It typically reduces as hormone levels stabilise.

Adult acne, by contrast, is often more complex. It tends to be cyclical and concentrated along the lower face — the jawline, chin, and neck — areas strongly associated with hormonal fluctuation. It can also present as deeper, more painful cystic lesions rather than surface-level whiteheads.

Common Triggers for Adult Acne

Adult acne rarely has a single cause. Common contributing factors include:

• Hormonal fluctuations — related to the menstrual cycle, perimenopause, polycystic ovarian syndrome (PCOS), or stopping hormonal contraception
• Stress — elevated cortisol triggers increased sebum production and inflammation
• Diet — high-glycaemic foods and dairy have been linked to acne in some individuals, though responses vary
• Compromised skin barrier — over-cleansing, using incorrect products, or using too many actives can disrupt the barrier and worsen breakouts
• Skincare ingredients — comedogenic ingredients in makeup, SPF, or moisturisers can block follicles

Not All Acne Is the Same — And Misdiagnosis Is Common

Two forms of acne that are frequently misidentified:

• Hormonal acne — Typically inflammatory or cystic, appearing cyclically around the jawline and chin.
• Fungal acne (Pityrosporum folliculitis) — Often mistaken for acne but caused by a yeast overgrowth in the follicle. It responds to antifungal treatment, not standard acne protocols — and many conventional acne products can make it worse.

If you've been treating acne for months without improvement, it's worth having a professional assessment to ensure you're treating the right thing.

Common Mistakes That Make Acne Worse

Some well-intentioned skincare habits can aggravate acne:

• Over-cleansing or using harsh foaming cleansers, which strips the skin and triggers a rebound increase in sebum
• Skipping moisturiser for fear of adding oil — dehydrated skin can produce more sebum
• Layering too many active ingredients without professional guidance
• Using physical scrubs on active breakouts, spreading bacteria and causing further inflammation

How We Treat Adult Acne at Le Beauty & Skincare

Our approach is always assessment-first. We begin with a thorough skin analysis to identify the type of acne, likely triggers, and the current state of the barrier before recommending treatment. From there, our clinical options include:

• Mandelic acid peels — particularly effective for hormonal and inflammatory acne. Mandelic is gentler on darker skin tones, as mandelic has a larger molecular structure that penetrates more slowly and with less irritation.
• Salicylic acid peels — target sebum and work within the follicle.
• Enzyme treatments — for clients whose skin is too reactive for acid peels, enzyme-based exfoliation offers a gentler route to clearer skin.

Your Homecare Routine for Acne-Prone Skin

A simple, consistent routine is often more effective than a complicated one. At Le Beauty, we typically prescribe:

• Morning: Gentle foaming cleanser → AquaPorin Hydrating Serum → oil-free mineral SPF 30+
• Evening: Double cleanse → Circadia Spot Stop for targeted application on active lesions → lightweight non-comedogenic moisturiser

We adjust this based on each client's specific skin type and concerns.
