Acne Treatment Guide: What Works for Pimples and Breakouts

Acne is one of the most common skin conditions, and it does not stop at the teenage years. Many adults deal with breakouts too. The good news is that most mild to moderate acne responds well to a few proven ingredients used consistently. This guide explains what causes pimples, which acne treatments are worth trying, how to build a routine around them, and when to get professional help.

What causes acne?

Acne develops when four things come together:

• Excess oil (sebum), often driven by hormones
• Clogged pores, when dead skin cells do not shed properly
• Bacteria (Cutibacterium acnes) multiplying inside the blocked pore
• Inflammation, which turns a blocked pore into a red, sore pimple

Different treatments target different parts of this process, which is why the right choice depends on the type of acne you have.

Types of acne

• Blackheads and whiteheads (comedones): clogged pores without much redness
• Papules and pustules: red bumps and pimples with a white or yellow centre
• Nodules and cysts: deep, painful lumps under the skin that can scar. These need a doctor.

Over-the-counter acne treatments that work

Salicylic acid

Salicylic acid is a beta hydroxy acid (BHA) that dissolves in oil, so it can get inside pores and loosen the build-up that causes blackheads and whiteheads. It is usually found at 0.5% to 2% in cleansers, toners and leave-on treatments. Shop salicylic acid skincare.

Benzoyl peroxide

Benzoyl peroxide kills acne-causing bacteria and helps clear pores, which makes it a good choice for red, inflamed pimples. Strengths range from 2.5% to 10%, and lower strengths are often just as effective with less dryness. Note that it can bleach towels, pillowcases and clothing.

Retinoids

Retinoids speed up skin cell turnover so pores stay clear, and they help with marks left behind. Adapalene is the most common option for acne, and your pharmacist or doctor can advise on availability and strength. Gentler cosmetic retinol products can help with texture but are milder than acne-strength retinoids. Retinoids are not recommended during pregnancy.

Azelaic acid and sulphur

Azelaic acid reduces bacteria and inflammation and also fades post-acne dark marks, so it suits sensitive skin and skin prone to pigmentation. Sulphur is a gentler, older option often used as a spot treatment.

Niacinamide

Niacinamide is not an acne treatment on its own, but it calms redness, helps balance oil and supports the skin barrier while stronger actives do their work. Our guide on vitamin C serum vs niacinamide explains how to fit it into a routine.

A simple acne skincare routine

Morning

1. Gentle face wash, or a salicylic acid cleanser
2. Niacinamide serum (optional)
3. Light, oil-free moisturiser
4. Non-comedogenic sunscreen

Evening

1. Cleanse
2. Your acne treatment: benzoyl peroxide, a retinoid or azelaic acid
3. Moisturiser

Start with one active and use it every other night for the first two weeks, then increase as your skin adjusts. Using several strong actives at once is the most common reason acne routines fail, because the irritation causes more redness and peeling. Do not skip moisturiser: dryness and peeling make people give up too early. Our guide to choosing a face moisturiser for your skin type covers what to look for on oily skin.

How long does acne treatment take?

Most treatments need 8 to 12 weeks of consistent use before you can judge them. Some people notice a brief flare in the first few weeks, especially with retinoids. If there is no improvement after three months, it is time to change approach.

Habits that make a difference

• Do not pick or squeeze pimples. It pushes inflammation deeper and raises the risk of scars and dark marks.
• Wash your face after sweating, and change pillowcases regularly.
• Choose makeup and sunscreen labelled non-comedogenic.
• Avoid harsh scrubs. Over-scrubbing irritates skin and can make acne worse.
• Keep phone screens and hands away from your face where you can.

When to see a doctor

See a doctor or dermatologist if you have:

• Deep, painful nodules or cysts
• Acne that is leaving scars
• No improvement after about three months of over-the-counter treatment
• Sudden acne in adulthood, especially with other symptoms such as irregular periods or unusual hair growth

A doctor can prescribe stronger options such as topical antibiotics, prescription retinoids, hormonal treatments or isotretinoin, which requires close medical supervision.

Frequently asked questions

What is the best acne cream?

There is no single best acne cream for everyone. For blackheads and whiteheads, salicylic acid or a retinoid is a good start. For red, inflamed pimples, benzoyl peroxide tends to work well. Browse our oily and acne-prone skin range or ask our pharmacists for help.

Can I use salicylic acid and benzoyl peroxide together?

Yes, many people do, but it can be drying. A common approach is a salicylic acid cleanser in the morning and benzoyl peroxide in the evening.

Does diet cause acne?

Diet is not the main cause, but some studies link high-sugar diets and, for some people, dairy to more breakouts. It is worth noticing your own patterns.

How do I get rid of acne marks?

Flat dark marks usually fade over months. Sunscreen, niacinamide, azelaic acid, vitamin C and retinoids can speed this up. Browse treatments for dark spots. Raised or pitted scars need treatment from a dermatologist.
