Acne in Adults: A Nigerian Guide

Hormonal breakouts, dark spots, and scarring — what actually works

Acne does not stop at adolescence. Adult acne — particularly hormonal acne in women — is increasingly common in Nigeria, often triggered by PCOS, stress, diet, or the wrong skincare products. Nigerian skin is also particularly prone to post-inflammatory hyperpigmentation (dark spots) after acne — making effective treatment even more important. This guide covers what works, based on evidence.

Signs and Symptoms

✓ Comedones (blackheads and whiteheads)
✓ Papules — small, raised, red bumps
✓ Pustules — papules with pus at the tip
✓ Nodules and cysts — deep, painful lumps (severe acne)
✓ Post-inflammatory hyperpigmentation (dark marks) after spots clear — particularly pronounced in darker skin
✓ Scarring — atrophic (pitted) or hypertrophic (raised) scars
✓ In women: worsening before period, jaw and chin distribution (hormonal pattern)

Risk Factors

When to Seek Help

Nodular or cystic acneNodules and cysts cause scarring and need prescription treatment — see a dermatologist.
Acne not responding to OTC treatment after 3 monthsPrescription retinoids, antibiotics, or hormonal treatment may be needed.
Acne with irregular periods or facial hair in womenSuggests PCOS — requires hormonal assessment alongside dermatology.
Significant psychological impactAcne depression and social withdrawal are common and valid — seek help for both.

Tests & Diagnosis

🧪 Clinical diagnosis
Acne is diagnosed clinically. Grading (mild/moderate/severe) guides treatment intensity.
🧪 Hormonal profile in women
LH/FSH ratio, testosterone, DHEAS, prolactin — if PCOS or hormonal acne pattern is suspected.
🧪 HbA1c and insulin resistance markers
PCOS and insulin resistance are linked to acne — may guide combined management.

Treatment Options

1
Gentle, non-comedogenic skincare routine
Mild gel or foam cleanser twice daily. Light, oil-free moisturiser. SPF 30 sunscreen (essential — prevents hyperpigmentation). Remove makeup before sleeping. Avoid heavy oils (cocoa butter, coconut oil) on the face — highly comedogenic.
2
Benzoyl peroxide (first-line OTC)
2.5–5% benzoyl peroxide kills acne bacteria and reduces inflammation. Apply to affected areas. Start with low concentration to reduce irritation. Bleaches fabrics — use old pillowcases.
3
Salicylic acid
2% salicylic acid clears pores and reduces comedones — available in many Nigerian pharmacies and skincare products. Good for blackheads and mild papular acne.
4
Niacinamide (5–10%)
Reduces sebum, calms inflammation, and reduces post-inflammatory hyperpigmentation — highly useful for Nigerian skin where dark marks are a major concern.
5
Prescription topical retinoids (tretinoin 0.025–0.05%)
The most evidence-based topical treatment for acne. Reduces all lesion types and prevents scarring. Takes 8–12 weeks to show effect. Causes initial purging — normal. Apply at night. Requires SPF in the morning.
6
Oral antibiotics (for moderate-severe acne)
Doxycycline or tetracycline for 3 months — reduces inflammation. Always combined with topical treatment. Do not use long-term without specialist review.
7
Combined oral contraceptive pill (for women)
Cyproterone acetate + oestrogen (Diane-35) is highly effective for hormonal acne. Other COCPs (Yasmin, Microgynon) also help. Takes 3–6 months for full effect.
8
Oral isotretinoin (for severe/cystic acne)
The most powerful acne treatment available. Requires strict monitoring (liver, lipids, mandatory contraception in women). Available in Nigeria from dermatologists. Dramatic results — many achieve permanent remission.

Frequently Asked Questions

Does eating fried food cause acne?
High glycaemic index foods (white rice, fried starchy food, sugary drinks) worsen acne in susceptible individuals by raising insulin and androgen levels. The direct causation from 'fried food' or 'chocolate' is weaker than the evidence for overall glycaemic load. Reducing high-GI foods is a useful component of acne management.
Can skin lightening creams cause acne?
Yes — steroid-containing skin lightening creams cause steroid acne: monomorphic small pustules all over the face, sometimes with rosacea-like flushing. This is very common in Nigeria. Stopping the cream is the first step — withdrawal must be gradual under supervision.
Why do I get dark marks after every pimple?
Post-inflammatory hyperpigmentation (PIH) is the skin's inflammatory response to acne — it is more pronounced in darker skin tones. The most effective approach: treat acne promptly (prevents new PIH), use SPF daily (prevents existing PIH darkening), and add niacinamide, azelaic acid, or vitamin C to fade existing marks.
Is popping pimples okay?
No — squeezing forces bacteria deeper and causes more inflammation, prolonging the spot and dramatically increasing PIH and scarring risk. Apply a spot treatment (benzoyl peroxide or salicylic acid) instead and let the pimple resolve.
How long before I see results from treatment?
Topical treatments take 8–12 weeks to show significant improvement. Oral treatments (antibiotics, isotretinoin) work faster. Do not change products every few weeks — give each treatment its full assessment period before deciding it isn't working.
