Acne Treatment in the UK: What Actually Works (A Pharmacist's Guide)

Understanding Acne

Acne is the most common skin condition in the UK, affecting around 95% of people aged 11-30 to some degree. But it's not just a teenage problem — adult acne is increasingly common, particularly in women.

Acne develops when:

1. Excess sebum (oil) is produced by the skin
2. Dead skin cells block hair follicles
3. Bacteria (Cutibacterium acnes) multiply in the blocked pore
4. Inflammation causes redness, swelling, and pain

Understanding this process helps explain why different treatments target different steps.

What Actually Works

1. Benzoyl Peroxide (Acnecide)

The gold standard pharmacy treatment for mild to moderate acne.

Benzoyl peroxide works by:

• Killing acne-causing bacteria
• Reducing inflammation
• Helping to unclog pores

Acnecide 5% Gel is available without prescription and is recommended as a first-line treatment by NICE (National Institute for Health and Care Excellence).

How to use it:

• Start with a thin layer once daily (evening) for the first week
• If tolerated, increase to twice daily
• Apply to the entire affected area, not just individual spots
• Use for at least 6-8 weeks before judging effectiveness
• Always use SPF during the day (benzoyl peroxide increases sun sensitivity)

Common side effects: Dryness, peeling, mild stinging — these usually improve after 2-3 weeks. Start slowly and build up.

Warning: Benzoyl peroxide bleaches fabrics. Use white pillowcases and towels.

2. Nicotinamide (Freederm)

A gentler alternative for sensitive skin.

Nicotinamide (vitamin B3) has anti-inflammatory and sebum-reducing properties. Freederm Treatment Gel contains 4% nicotinamide and is:

• Fragrance-free
• Less drying than benzoyl peroxide
• Suitable for sensitive skin
• Good for mild acne and maintenance

It won't work as fast as benzoyl peroxide for moderate acne, but it's better tolerated and a good option for people who find BP too harsh.

3. Salicylic Acid (0.5-2%)

A beta-hydroxy acid (BHA) that:

• Exfoliates inside the pore
• Reduces blackheads and whiteheads
• Has mild anti-inflammatory properties

Available in many cleansers and spot treatments. Works best for comedonal acne (blackheads and whiteheads) rather than inflammatory acne.

4. Retinoids (Adapalene/Differin)

Adapalene 0.1% gel (Differin) is available without prescription in many countries but requires a prescription in the UK. It's highly effective for:

• Unclogging pores
• Preventing new breakouts
• Improving skin texture

If over-the-counter treatments aren't working, ask your GP about adapalene.

A Simple, Effective Routine

Overcomplicating your skincare makes acne worse. Here's the essentials:

Morning

1. Gentle cleanser — CeraVe, Cetaphil, or La Roche-Posay (avoid foaming "deep clean" washes)
2. Moisturiser — yes, even if your skin is oily. Dehydrated skin produces more oil
3. SPF 30+ — especially if using benzoyl peroxide

Evening

1. Same gentle cleanser — double cleanse if wearing makeup
2. Treatment — benzoyl peroxide OR nicotinamide (not both at the same time)
3. Moisturiser — a lightweight, non-comedogenic formula

That's it. Three products morning, three evening. Consistency matters more than complexity.

Common Mistakes

• Over-washing — cleansing more than twice daily strips the skin barrier and worsens acne
• Using too many actives — layering benzoyl peroxide + salicylic acid + retinol will destroy your skin barrier
• Picking and squeezing — introduces bacteria and causes scarring
• Expecting overnight results — most acne treatments need 6-12 weeks to show full effect
• Stopping treatment once skin clears — acne is often chronic; maintenance treatment prevents relapse
• Harsh scrubs and "detox" products — physical exfoliation irritates inflamed skin

What Doesn't Work

• Toothpaste on spots — contains irritants, can cause chemical burns
• "Detox" supplements — your skin isn't toxic, it's inflamed
• Expensive "miracle" serums — most are just clever marketing
• Cutting out all dairy/sugar — the evidence is weak and inconsistent (unless you notice a personal trigger)
• Tea tree oil as a primary treatment — mildly antibacterial but far less effective than benzoyl peroxide

When to See Your GP

See your doctor if:

• Over-the-counter treatments haven't worked after 8-12 weeks
• You have deep, painful cystic acne
• Acne is causing scarring
• Acne is significantly affecting your mental health
• You're a woman with acne plus irregular periods or excess hair growth (may indicate hormonal causes)

Your GP can prescribe:

• Topical retinoids (adapalene)
• Topical antibiotics (clindamycin, usually combined with benzoyl peroxide)
• Oral antibiotics (lymecycline, doxycycline)
• Combined oral contraceptive pill (for hormonal acne in women)
• Referral to dermatology for isotretinoin (Roaccutane) in severe cases
