How to Identify and Treat Each Type of Acne
Types of Acne Explained: How to Identify Your Lesions and Choose the Right Treatment
If you’re treating a painful nodule the same way you treat a blackhead on your nose, something’s off. And it’s not your fault – nobody explained that different types of acne need completely different approaches. The right ingredient for the wrong lesion type simply won’t work.
The most common mistake in at-home skincare? Choosing the correct ingredient – but for the wrong type of lesion. Acne is usually a mix: comedones (non-inflammatory) and inflammatory lesions (papules, pustules, nodules, cysts). That’s where all the difference starts.
What’s Actually Happening in Your Skin
Acne originates in the pilosebaceous unit – the hair follicle and its attached sebaceous gland. Four things typically happen:
1 Excess sebum production
The gland produces more oil than the skin needs.
2 A “plug” of cells forms
Dead skin cells block the follicle opening.
3 Cutibacterium acnes multiplies
The bacteria that contributes to acne inflammation thrives in the blocked follicle.
4 Inflammation follows
The immune response kicks in – and the lesion becomes red, swollen, or painful.
The proportion of each factor varies from person to person – and even from one area of the face to another. There is no universal routine that works for everyone, because there is no single type of acne.
How Each Lesion Type Looks – and What to Do About It
Comedonal acne – blackheads and whiteheads
Whiteheads
- Small, skin-coloured bumps
- Covered by a thin film of skin
- Closed at the surface
Blackheads
- Dilated pores with a dark plug
- Not dirt – it’s oxidised sebum
- Scrubbing makes it worse
How to recognise them: Numerous, fairly uniform, painless, non-pulsating. Skin feels rough to the touch – especially on the forehead and nose.
What actually helps
- Gentle cleansing
- Chemical exfoliation (BHA)
- Patience: 8–12 weeks minimum
What makes it worse
- Abrasive scrubs
- Physical extraction at home
- Over-cleansing
Inflammatory acne – papules and pustules
- Red or pink bumps
- No white head
- Tender to the touch
Pustules
- Like papules, but with a white tip
- White or yellow visible content
- Do not squeeze
How to recognise them: Redness, sensitivity, appearing in waves – most often on the cheeks, chin, and jaw. Squeezing significantly increases the risk of post-inflammatory marks and scarring.
What actually helps
- Anti-inflammatory actives
- Benzoyl peroxide (if tolerated)
- BHA for pores
- Hydrocolloid patches
What makes it worse
- Skipping moisturiser
- Squeezing or picking
- Too many new products at once
Nodular and cystic acne – the deep, painful kind
Nodules
- Large, hard, under-the-skin bumps
- No clear central point
- Persist for weeks
Cysts
- Deep, painful lesions
- High risk of scarring
- Need professional care
How to recognise them: Deep-set, long-lasting, painful when you talk or touch the area. An aggressive at-home approach – layering acid over acid, over-drying – makes this type significantly worse.
This is where at-home routines have limits. If you have recurring nodules or cysts, or you can see scarring forming, please see a dermatologist. This is not the moment for DIY.
Why Location and Timing Matter Too
Hormonal acne
Inflammatory lesions on the chin, jaw, and neck – often flaring before menstruation. The routine needs to be anti-inflammatory but gentle. An impaired barrier makes this type look worse, not better.
Mechanical acne
Appears at friction points – from masks, helmets, or phone contact. The fix is simple: keep anything that touches your face clean, and avoid heavy or pore-blocking products in those zones.
Body acne
Sweat, tight clothing, and hair products that drip onto the skin can all cause breakouts. Note: if “acne” on your back is itchy, uniform, and doesn’t respond to anything, it may be folliculitis, which needs a different treatment entirely.
The right ingredient for the wrong lesion type simply won’t work. More is not more – it’s just more irritation.
How to Choose Products Without Getting Lost
Keep it simple: one main active + something for the barrier + SPF. That’s it.
Comedones
A BHA used a few times a week is more effective than any scrub. If your skin is also sensitive, start infrequently and build up gradually.
Papules / Pustules
One anti-acne active in the evening + lightweight hydration in the morning + hydrocolloid patches when needed. Not ten new products every week.
Nodules / Cysts
Your at-home routine plays a support role, not a rescue role. The goal is reducing irritation – not escalating with aggressive layers.
A Simple Routine That Works for Most Acne-Prone Skin
Morning
Gentle cleanser → lightweight moisturiser → SPF (non-negotiable if you’re using acids — without it, marks become permanent).
Evening
Cleanser → chosen active (based on your lesion type) → soothing cream if skin feels tight.
If you feel constant stinging, diffuse redness, or flaking, you’re overdoing it. An irritated skin barrier amplifies inflammation, even when you’re using the right ingredient.
Products Worth Your Attention
Acnemy Zitaid
For comedonal acne and congested pores. Formulated to gradually improve the appearance of skin with excess sebum.
Acnemy Zitcontrol
For recurring inflammatory lesions. A targeted cream is more effective than rotating through ten products week after week.
Acnemy Postzit
For post-acne marks and uneven texture. An exfoliating serum to use with patience – not daily – to gradually even out skin tone.
Myths to Leave Behind
✕ “If it stings, it’s working.”
No. Constant stinging is a sign of a compromised skin barrier — not a sign of efficacy. Effective skincare doesn’t need to hurt.
✕ “Blackheads are just dirt.”
The dark colour comes from oxidation, not poor hygiene. You could wash your face ten times a day, and they’d still be there without the right type of exfoliation.
✕ “You need to dry out acne.”
Aggressive drying irritates the skin barrier, triggers more sebum production, and increases inflammation. It’s the number one vicious cycle in acne-prone skincare.
The Bottom Line
Acne is not one thing, and it doesn’t respond to one product – no matter how viral it is on TikTok. The more clearly you understand what type of lesions you’re dealing with, the shorter, cheaper, and more effective your routine becomes.
You don’t need 12 steps. You don’t need everything that’s trending. You need a few well-chosen products, real patience (not “I used it for three days and nothing happened”), and – when the situation calls for it – a dermatologist, not another serum discovered at 2 am.
Frequently Asked Questions
What are the most common types of acne?
The most common types are comedonal acne (blackheads and whiteheads), inflammatory acne (papules and pustules), and nodular or cystic acne. Each looks different, behaves differently, and responds to different treatments.
How do I recognise comedonal acne?
Comedonal acne appears as blackheads and whiteheads — painless, uniform, and concentrated on the forehead and nose. The skin may feel rough or bumpy to the touch. It responds well to chemical exfoliation, particularly BHA (salicylic acid).
What is inflammatory acne?
Inflammatory acne includes papules (red, tender bumps without a head) and pustules (similar but with a visible white or yellow tip). These tend to appear in waves – most commonly on the cheeks, chin, and jaw — and are sensitive to the touch.
When should I see a dermatologist for acne?
See a dermatologist if you have nodules or cysts, recurring painful lesions, or visible scarring. Deep acne rarely responds well to at-home routines alone and often needs prescription-strength treatment to prevent permanent skin damage.
Can acne be treated at home?
Mild to moderate acne – comedones, occasional papules and pustules – can often be managed well with a consistent routine. Severe or deep acne (nodules, cysts) generally needs professional evaluation. An at-home routine in those cases is supportive, not curative.
