Pimples and Acne Explained: Causes, Types & Best Treatment Options
Do pimples, breakouts, or acne keep coming back and affecting your skin confidence?
Acne is a common skin condition that leads to pimples, clogged pores, inflammation, and sometimes long-term marks or scars. It occurs when excess oil, dead skin cells, and bacteria block hair follicles, resulting in visible breakouts on the skin.
Acne can range from mild occasional pimples to severe cystic acne that may leave marks or scars if not treated properly. With the right diagnosis and customised pimple and acne treatment, breakouts can be controlled, and clear, healthy skin can be restored.

What is Acne?
Acne (also known as acne vulgaris) is a skin condition that affects the pilosebaceous unit (hair follicles + oil glands). When excess oil (sebum), dead skin cells, and bacteria clog pores, it leads to pimples, inflammation, and breakouts.
Common concerns include:
Pimples on face
- Whiteheads and blackheads
- Painful acne bumps
- Post-acne marks and scars
With proper acne treatment, these concerns can be effectively managed and prevented.
Where Do Pimples and Acne Appear?
- Face (forehead, cheeks, nose, chin,
jawline)
- Neck
- Chest
- Back (back acne)
- Shoulders and arms
Acne Causes (Why Pimples Occur)
Overactive sebaceous glands clog pores and trigger breakouts.

Common in puberty, PCOS, pregnancy, and stress-related acne.
Dead skin cells + oil buildup lead to whiteheads and blackheads.
Acne associated bacteria (Cutibacterium acnes) contribute to inflammation in clogged pores.

Poor diet, lack of sleep, dehydration, and stress worsen acne.

Heavy makeup or comedogenic products block pores.

Acne-prone skin can run in families.
Steroids or hormonal treatments may trigger acne.
Types of Acne
Whiteheads
Closed clogged pores that appear as small white bumps.
Blackheads
Open pores clogged with oil that oxidise and turn dark.
Papules
Small red, inflamed bumps without pus.
Pustules
Pus-filled pimples caused by infection and inflammation.
Nodules
Large, painful lumps deep under the skin that may lead to scars.
Cystic Acne
Severe, deep, pus-filled acne that often leads to scarring.
Symptoms of Acne

Acne Marks vs Acne Scars (Important Difference for Treatment Plan)
| Feature | Post-Acne Marks | Acne Scars |
|---|---|---|
| Nature | Colour change | Structural skin damage |
| Appearance | Brown, black, red or pink marks | Depressions (pits) or raised scars |
| Skin Texture | Smooth | Uneven / rough |
| Cause | Melanin or blood vessel changes | Collagen damage |
| Types | PIH (dark spots), PIE (red marks) | Ice pick, boxcar, rolling, hypertrophic |
| Treatment | Topicals, peels, sunscreen | Collagen-stimulating treatments |
| Permanence | Temporary | May be long-term without treatment |
Types of Acne Scars
Atrophic Scars (Depressed Scars)
These scars appear as small indentations in the skin due to collagen loss during healing.
Ice Pick Scars
Deep, narrow pits that extend into the dermis and give the skin a punctured appearance.
Boxcar Scars
Round or oval depressions with defined sharp edges that create uneven skin texture.
Rolling Scars
Wide, shallow depressions with gently sloping edges that make the skin appear wavy or uneven.

Hypertrophic Scars (Raised Scars)
These scars occur due to excess collagen production, resulting in thick, raised tissue over the skin surface.
