Acne and pimples: why they happen and a step-by-step plan to clear them

Acne affects most people at some point: teenagers, adults in their 20s and 30s, women around their periods, men with oily skin and beard-area breakouts. It is not caused by being dirty, and it is not your fault. It is also very treatable.

This guide explains why pimples form, the habits that quietly make them worse, a simple routine that works for most skin, and when it is time to get help.

How a pimple forms

Four things come together:

1. Oil. Hormones, especially androgens, make oil glands produce more sebum. This is why acne often starts at puberty and flares before periods.
2. Blocked pores. Dead skin cells stick together with the oil and plug the pore. A closed plug is a whitehead; an open one that darkens in air is a blackhead.
3. Bacteria. A bacterium that lives on everyone’s skin multiplies inside the blocked, oily pore.
4. Inflammation. The body reacts, and the pore becomes a red, swollen pimple. When the reaction is deep, it becomes a painful lump (nodule or cyst), and these are the ones most likely to scar.

Types of acne

• Comedones: blackheads and whiteheads, often on the nose, forehead and chin
• Papules and pustules: red bumps and pus-filled pimples
• Nodules and cysts: deep, painful lumps that last weeks
• Body acne: on the back, chest and shoulders, common in men and in hot weather
• Adult hormonal acne: around the jaw, chin and neck, common in women, sometimes with irregular periods

Things that make acne worse

• Squeezing and picking. It pushes the infection deeper and causes marks and scars.
• Heavy, oily products: thick creams, hair oils that run onto the forehead, oily sunscreens and makeup.
• Harsh scrubbing and strong face washes used many times a day. Irritated skin breaks out more.
• Sweat and humidity, especially under helmets, masks, caps and tight sports clothes.
• Stress and poor sleep, which raise hormones that drive oil.
• Sugary foods and, for some people, a lot of milk and whey protein. The link is real but varies from person to person.
• Steroid creams and some "fairness" creams, which cause their own type of acne.
• Dirty pillow covers and phones that rest against the face.

What does not cause acne: not washing enough, or eating oily food as such. The oil on your plate is not the oil on your face.

A simple routine that works for most people

Morning

1. Gentle cleanser. A mild, non-soap face wash. For oily skin, one with salicylic acid can help.
2. Light, oil-free moisturiser or gel. Even oily skin needs it, especially when using acne creams that dry the skin.
3. Sunscreen, gel or fluid, labelled non-comedogenic. It also stops pimple marks from darkening.

Night

1. Cleanse again, removing sunscreen and makeup properly.
2. An acne treatment chosen for your skin. Common ones are benzoyl peroxide, adapalene (a retinoid), azelaic acid or salicylic acid. Start with a pea-sized amount every other night, then increase as your skin adjusts.
3. Moisturiser if the skin feels dry.

Give any routine 6 to 8 weeks before judging it. Acne treatments work by preventing new pimples, and the pores that are already blocked take time to clear.

Habits that help

• Change pillow covers two or three times a week.
• Wash your face after sweating, and wash helmets and caps regularly.
• Keep hair oil off the forehead, and wash it out rather than leaving it on for days.
• Clean your phone screen.
• Do not squeeze. If a pimple is very painful, a clinic can treat it safely.

When clinic treatment helps

See a doctor if:

• You have deep, painful lumps or cysts
• Acne is leaving marks or pits
• A good routine has not helped after two to three months
• Acne started suddenly in adulthood, or comes with irregular periods, extra facial hair or weight gain
• It is affecting your confidence or mood

Clinic options include:

• Chemical peels, especially salicylic and mandelic peels, to unclog pores and calm inflammation
• Professional extraction of blackheads and whiteheads, done gently without scarring
• Laser and light treatments to calm active acne and reduce oil
• Prescription creams and tablets, such as antibiotics for a short course, or other medicines for severe or stubborn acne
• Hormonal evaluation for adult women with signs of PCOS

After the acne: marks and scars

Once breakouts are under control, the marks left behind can be treated. Flat dark marks fade with peels, laser toning and sunscreen. Pitted scars need collagen-building treatments such as RF microneedling. The single best way to avoid scars is to treat acne early and stop picking.

Common questions

Will toothpaste dry a pimple? It may dry it a little, but it also irritates the skin and often leaves a dark mark. A spot treatment with benzoyl peroxide or salicylic acid is safer.

Should I stop using moisturiser because my skin is oily? No. Use a light, oil-free one. Dehydrated skin can make more oil and become irritated by acne treatments.

Does acne go away on its own? Teenage acne often improves with age, but it can leave scars in the meantime. Treating it early protects your skin.

The bottom line

Acne is common, treatable, and not a sign of poor hygiene. A gentle routine, patience and avoiding the habits that make it worse will help most people. Deep or scarring acne deserves early treatment.
