What are acne scars?
Acne scars form when the skin's healing response to deep or prolonged inflammation (typically from cystic or nodular acne) doesn't fully restore the original smooth texture. There are several patterns — ice-pick scars (narrow, deep pits), boxcar scars (broader, more defined depressions), rolling scars (shallow, undulating texture), and less commonly, hypertrophic or keloid scars (raised tissue).
The pattern and depth of scarring guides which treatments will be most effective, which is why an individual assessment matters more than a one-size-fits-all approach.
Why scarring happens
- Deep, inflamed acne lesions — cysts and nodules carry the highest scarring risk.
- Delayed treatment — the longer significant acne goes untreated, the greater the cumulative scarring risk.
- Picking or squeezing lesions, which increases inflammation and scarring likelihood.
- Genetics — some people scar more readily than others from similar acne severity.
Recognising the type
- Ice-pick scars: narrow, deep, sharply defined pits.
- Boxcar scars: broader depressions with defined edges.
- Rolling scars: shallow, wave-like unevenness in the skin's surface.
- Hypertrophic/keloid scars: raised, firm tissue, more common on the chest and back.
Assessment
We assess the pattern, depth, and distribution of your scarring under good lighting to determine the most suitable treatment approach — often a combination of techniques gives the best result, since most people have more than one scar type.
Treatment options
Laser resurfacing
Helps improve overall texture and stimulate collagen remodelling, via our Ethera Laser platform.
Skin needling
Stimulates the skin's own collagen production to gradually soften indented scarring.
Corticosteroid injections
For raised hypertrophic or keloid acne scars.
Combination approach
Most patients benefit from a tailored combination of treatments over a series of sessions, rather than a single technique.
Reducing future scarring
- Treat active, moderate-to-severe acne promptly — this is the single most effective way to prevent new scarring.
- Avoid picking or squeezing acne lesions.
- Daily sunscreen helps prevent scars becoming more noticeable through pigmentation changes.
Frequently asked questions
Can acne scars be completely removed?
Full erasure usually isn't realistic, but meaningful, often significant improvement in texture and appearance is achievable with the right combination of treatments. Setting realistic expectations at your consultation helps you feel confident in the plan.
How many treatment sessions are needed?
This depends on the scar type, depth, and treatment chosen, but most approaches involve a series of sessions over several months for best results, with gradual visible improvement along the way.
Should I treat my acne scars while I still have active acne?
Generally, it's best to get active acne under control first — treating scarring while acne is still flaring can be less effective and risks new scarring during the process. Your doctor can advise on the right timing for you.
