Acne is not just a teenage condition. According to the British Association of Dermatologists (BAD), approximately 15% of women aged 25–44 experience clinically significant acne, with many cases driven by hormonal fluctuations. The pattern is distinctive: deep, cystic lesions concentrated along the jawline, chin and lower cheeks, often flaring in the week before menstruation.

Community pharmacists see these patients regularly — women who have "tried everything" from the skincare aisle but find that their acne returns each month. With the renewed Women's Health Strategy highlighting the importance of accessible healthcare for women, pharmacists are in a strong position to guide effective OTC treatment and identify when referral is needed.

What makes hormonal acne different?

Hormonal acne in adult women is driven by androgens — particularly testosterone and dihydrotestosterone (DHT) — which stimulate sebaceous gland activity. The sensitivity of sebaceous glands to androgens varies between individuals, which explains why women with normal hormone levels can still develop hormonal acne.

Key distinguishing features:

OTC treatment options

Pharmacists can recommend a stepped approach to OTC management:

Benzoyl peroxide (first-line OTC)

Benzoyl peroxide remains the most effective OTC acne treatment, with decades of evidence behind it. It works as an antimicrobial (killing Cutibacterium acnes) and a comedolytic (unblocking pores), without contributing to antibiotic resistance.

• 2.5% formulations are as effective as 5% or 10% for most patients, with less irritation
• Apply once daily at night to affected areas (not individual spots)
• Warn patients that it bleaches fabrics — use white pillowcases
• Results take 4–6 weeks; persistence is essential
• Can be combined with other actives (see below)

Salicylic acid

A beta-hydroxy acid (BHA) that penetrates oil-filled pores to dissolve dead skin cells. Best for comedonal acne (blackheads and whiteheads) and mildly inflammatory lesions. Concentrations of 0.5–2% in cleansers or leave-on products are standard.

Niacinamide

Niacinamide (vitamin B3) at 4–5% concentration has evidence for reducing sebum production and improving skin barrier function. A 2006 study in the International Journal of Dermatology found 4% niacinamide gel comparable to 1% clindamycin gel for inflammatory acne. It is well tolerated and can be layered with other actives.

Azelaic acid

Available OTC in the UK at up to 10% (higher concentrations are prescription-only), azelaic acid is anti-inflammatory, antimicrobial and reduces post-inflammatory hyperpigmentation — a common concern for women with darker skin tones. It is pregnancy-safe, making it a useful option for women planning conception.

What pharmacists should advise about skincare routines

• Gentle cleanser — avoid harsh scrubs, which worsen inflammation
• One active at a time — introducing multiple new products simultaneously makes it impossible to identify what works and increases irritation risk
• Moisturiser — even oily, acne-prone skin needs hydration, especially when using drying actives like benzoyl peroxide. Non-comedogenic, fragrance-free formulations are appropriate
• SPF — several acne actives increase photosensitivity; daily sunscreen (SPF 30+, non-comedogenic) is advisable
• Patience — OTC treatments take a minimum of 6–8 weeks to show meaningful improvement. Setting this expectation upfront reduces premature abandonment

Products to avoid

Pharmacists should steer patients away from:

• Toothpaste on spots — contains irritants (sodium lauryl sulphate, menthol) that can worsen inflammation and cause contact dermatitis
• Coconut oil — highly comedogenic; frequently worsens acne
• "Natural" or "detox" products without evidence-based actives — marketing claims do not substitute for clinical data
• Abrasive scrubs and exfoliating brushes — mechanical irritation triggers inflammation and can spread bacteria

When to refer

OTC treatment has genuine limitations for hormonal acne, particularly the deep, cystic variant. Referral to a GP is appropriate when:

• OTC treatments have been used consistently for 8–12 weeks without adequate improvement
• Acne is leaving scars (early referral prevents permanent scarring)
• The patient reports significant psychological distress — acne in adult women is strongly associated with anxiety and depression
• The patient is interested in hormonal treatment (combined oral contraceptive, spironolactone, co-cyprindiol)
• Acne is accompanied by other signs of androgen excess (hirsutism, scalp hair thinning, irregular periods) — which may suggest PCOS or another endocrine condition warranting investigation

The psychological dimension

Adult acne disproportionately affects women's mental health. A 2018 study in the British Journal of Dermatology found that acne patients had a 63% increased risk of developing major depressive disorder compared to matched controls. Pharmacists who acknowledge the emotional impact — rather than dismissing acne as cosmetic — provide a more supportive consultation.

Pharmacy's role in accessible skincare

With over 13,000 pharmacies across England, the pharmacy counter is where many women seek skincare advice. PharmSee's vacancy tracker shows 1,742 active roles nationally, reflecting a workforce that handles these consultations daily. Effective guidance — recommending evidence-based actives, setting realistic timelines, and referring when OTC treatment reaches its limits — is exactly the kind of accessible women's healthcare the Women's Health Strategy envisions.
