Acne and acne scarring treatment in London

Control the acne first. Then identify the scar type, because ice pick, boxcar and rolling scars each need a different technique and a staged plan.

In short

Can acne scars be removed?

Acne scars can be substantially improved but not erased. The technique depends on the scar type: ice pick, boxcar, rolling and raised scars all respond differently. Flat red or brown marks are usually not scars at all and often fade without procedural treatment.

Active acne is a medical condition

If you are still getting inflamed spots, the correct first appointment is with a GP or a dermatologist, not with an aesthetic clinic. Effective treatment for acne exists, it is available on the NHS, and it works. Untreated inflammatory acne produces new scars while you are paying to improve the old ones.

This is not a technicality. Resurfacing skin that is actively breaking out creates fresh damage, and ongoing inflammation beneath the surface undermines the remodelling you are trying to achieve. A clinic offering to begin scar treatment on actively inflamed skin is not doing you a favour.

If you have taken isotretinoin

There is longstanding caution about resurfacing within a period after finishing isotretinoin. Current thinking is more nuanced than it once was. It is a specific conversation to have with a medical practitioner who knows your history, not a question to settle from a website.

Identify what you actually have

Look at your skin in raking light from the side rather than straight on under a bathroom bulb. Work out whether you are looking at a change in the surface contour or only a change in colour. Everything follows from that.

Ice pick
Narrow, deep, sharply defined pits. The hardest type. They extend deep into the dermis and surface resurfacing achieves little.
Boxcar
Wider depressions with defined vertical edges, round or oval. Respond to resurfacing and to techniques that break down the edge.
Rolling
Broad, soft, undulating depressions with sloping edges, caused by fibrous tethers pulling the skin down from beneath. Respond best to releasing the tether.
Hypertrophic and keloid
Raised scars, more common on the chest, back and jawline. Treated completely differently, often with intralesional injection, and made worse by resurfacing.
Post-inflammatory erythema
Flat red or purple marks where a spot was. Not a scar. Fades over months and can be improved with vascular light treatment.
Post-inflammatory hyperpigmentation
Flat brown marks. Not a scar. Fades over months to years with topicals and strict sun protection.

Most people have a mixture, which is exactly why single-treatment plans underperform.

The techniques, matched to the type

Subcision

A needle or cannula is passed under a rolling scar to divide the fibrous bands tethering it downward, so the scar rises because it is no longer being pulled. This is the treatment of choice for rolling scars and nothing applied to the surface substitutes for it. Bruising is significant for a week or more.

Focal chemical treatment of ice pick scars

A high concentration acid applied precisely into the pit with a fine applicator, prompting the walls to contract and the base to lift. Repeated over several sessions, and the only realistic non-surgical option for narrow deep pits.

Fractional laser

Columns of controlled injury prompting remodelling. Effective for boxcar scars and general texture, with settings adjusted carefully in darker skin. See laser resurfacing.

Radiofrequency microneedling

Heat delivered into the dermis with less surface disruption, which is why it is frequently the preferred device in skin of colour. See radiofrequency microneedling.

Microneedling

Lower risk, lower intensity, more sessions. Reasonable for shallow scarring and for people who cannot take downtime.

Punch techniques

Surgical excision or elevation of individual deep scars, trading a pit for a fine line, which is usually a good trade.

What a real plan looks like

A serious plan is a sequence rather than a package, and it runs over six to twelve months.

  1. Get the acne controlled, medically if needed, and keep it controlled.
  2. Address tethering with subcision where rolling scars are present.
  3. Resurface across several sessions with a device chosen for your skin type.
  4. Treat individual resistant scars with focal techniques.
  5. Manage residual redness and pigmentation last, since both fade with time anyway.
  6. Maintain, with sun protection and continued acne control.

Expect improvement rather than erasure. A well-executed plan can make scarring substantially less noticeable in normal light and in photographs, which is what most people actually want. Skin that reads as never having had acne is not an available outcome.

The aim is skin that stops being the first thing you notice in the mirror, not skin that never had acne.

Risks

  • Post-inflammatory hyperpigmentation, the most common problem and the main reason settings must be adapted for skin of colour.
  • Prolonged redness after ablative treatment.
  • Infection, including reactivation of cold sores after resurfacing.
  • New scarring where treatment was too aggressive or aftercare was poor.
  • Marked bruising after subcision.
  • No meaningful improvement, which is far more likely when the scar type was misidentified.

Ask which specific scar types the practitioner has identified on your face and which technique each one is receiving. A single treatment proposed for everything means the assessment was not done.

Who should be doing this

Scar work sits at the medical end of this field. It involves breaking skin at depth, managing complications and often prescribing. Look for a medically qualified practitioner with specific experience in acne scarring, standardised photography, and a willingness to describe a staged plan rather than sell a course of one thing.

  1. Which scar types do I have, and where?
  2. What is the sequence, and over what period?
  3. What improvement would you expect, in plain terms?
  4. How do you adapt for my skin type?
  5. What photographs will you take, and under what conditions?
  6. What happens if I do not improve?

See how to read results for what a fair photographic comparison looks like.

Common questions

Can acne scars be completely removed?

No. Substantial improvement is realistic. Complete removal is not, and anyone promising it is overselling.

Do I have scars or marks?

Look in side lighting. If the surface contour is unchanged and only the colour differs, those are post-inflammatory marks rather than scars, and they usually fade on their own.

How long does scar treatment take?

A realistic plan runs six to twelve months across several sessions and usually more than one technique.

What treats rolling scars best?

Subcision, which releases the fibrous tethers pulling them down. Resurfacing alone tends to underperform on this type.

Can I treat scars while still breaking out?

No. Control the acne first. Treating scars on actively inflamed skin creates new ones.

Is laser safe for darker skin with acne scarring?

It can be with careful device selection, though radiofrequency microneedling is often preferred because it disrupts the surface less.

Will my scars come back?

Treated scars do not return, but new acne creates new scarring, so long-term acne control is part of the plan rather than separate from it.
