Laser resurfacing and microneedling can both improve the appearance of atrophic acne scars, but neither is automatically the better choice. The most appropriate option depends on the pattern and depth of scarring, skin tone and pigmentation risk, active skin concerns, recovery time, and the improvement you hope to achieve. Both treatments create a controlled stimulus that supports skin remodelling and collagen production, but they do this in different ways.
At Clinic 22, treatment for acne scarring is planned around an individual skin assessment. The aim is usually to soften the visibility of scars, improve texture, and create a smoother-looking skin surface over time, rather than promise complete scar removal.
How laser resurfacing and microneedling work
Laser resurfacing uses fractional laser energy to create very small, controlled treatment zones within the skin. At Clinic 22, iPixel laser resurfacing is used to support skin renewal and improve concerns including uneven texture, enlarged pores, and acne-related scarring. The surrounding skin is left intact between the treated areas, supporting the healing process.
SkinPen microneedling uses sterile, single-use needle cartridges to create controlled micro-channels in the skin. This stimulates the skin’s repair response and supports gradual collagen and elastin production. It can be used to improve the appearance of atrophic acne scars, including rolling and boxcar scars, alongside broader texture concerns.
In practical terms, laser resurfacing is an energy-based resurfacing treatment, while microneedling is a mechanical collagen-stimulation treatment. Both can be valuable options, but the treatment settings, intensity, and aftercare are not interchangeable.
| Consideration | Laser resurfacing | SkinPen microneedling |
|---|---|---|
| How it works | Fractional laser energy creates controlled microscopic treatment zones. | Sterile needles create controlled micro-channels. |
| Main focus | Skin renewal, texture, tone, pores, and acne-related scarring. | Collagen stimulation for scars, texture, pores, and skin quality. |
| Recovery planning | May involve a more noticeable short recovery period, depending on treatment intensity. | Redness and warmth commonly settle within 24–48 hours. |
| Course of treatment | Depends on the skin concern, treatment settings, and response. | A course is commonly needed, with plans individualised. |
| Key assessment factors | Scar pattern, skin quality, sun exposure, and pigmentation risk. | Scar pattern, skin thickness, healing response, and treatment goals. |
Which treatment is better for acne scars?
There is no single answer because acne scars are not all the same. Some are shallow and broad, some have defined edges, and some are narrow and deeper. Rolling scars may also be influenced by fibrous bands beneath the skin, while ice-pick scars can be particularly deep and narrow.
Treatment choice should therefore start with the scar type, rather than a general preference for laser or microneedling. A person with a mixture of scar types may need a staged or combination approach, or may benefit from discussing other specialist options where appropriate.
Research does not support a simple claim that one treatment is best for every patient. Studies comparing fractional laser and needling-based treatments have reported variable results, partly because they use different devices, treatment settings, scar grading systems, skin types, and treatment schedules. Scar type, skin type, recovery expectations, and the possibility of post-inflammatory pigmentation are all relevant to treatment planning.
It is also important not to assume that findings for one laser type apply identically to every laser system. This is one reason a treatment plan should be based on an in-person assessment rather than online before-and-after images alone.
Clinical Note from Nurse Rhi Bell
At Clinic 22, acne-scar treatment is planned around an individual skin assessment. The focus is usually on softening the visibility of scars, improving texture, and supporting a smoother-looking skin surface over time, with realistic expectations about the limits of treatment.
Recovery time and aftercare: an important difference
Recovery tolerance often has a significant influence on the choice between laser resurfacing and microneedling. Laser resurfacing can produce visible redness and temporary sensitivity as the skin renews, so it may suit people who can plan for a short period of social downtime and follow aftercare and sun-protection advice carefully.
Microneedling usually has a shorter visible recovery period. Following SkinPen treatment, the skin may look red and feel warm, similar to mild sun exposure, for up to 24–48 hours. Clinic 22 advises avoiding make-up for the first 24 hours, and avoiding heat, strenuous exercise, and sun exposure during the initial recovery period.
Both treatments require careful sun protection. UV exposure can affect healing and may contribute to uneven pigmentation, particularly in skin that is prone to post-inflammatory hyperpigmentation. The intensity, timing, and suitability of treatment should be adjusted accordingly.
What results can you realistically expect?
Acne-scar improvement develops gradually. The skin needs time to remodel, and a single session rarely changes established scarring dramatically. Microneedling is commonly planned as a course, with treatment intervals and the number of sessions determined by the concern and individual response.
Laser resurfacing may also be planned as a course, although the number and spacing of sessions should be determined by the treatment intensity, skin response, and the specific concern being addressed.
Results vary with scar depth, scar type, ongoing acne activity, skin health, age, smoking, sun exposure, and adherence to aftercare. Improvement in texture and the contrast between scars and surrounding skin can be meaningful, but deeper scars may remain visible. This is why realistic goals matter as much as treatment selection.
When should acne scarring be assessed more carefully?
If you have active, inflamed acne, it is sensible to discuss managing this first. Treating active breakouts and reducing ongoing inflammation can help limit the formation of new scars and can make the remaining scar pattern easier to assess.
Further clinical assessment is important if scarring is severe, or if you have a history of pigment changes or unusual scarring after injury. NICE advises considering referral to a consultant dermatologist-led team with expertise in scarring management for severe acne-related scarring. View NICE guidance on acne-related scarring.
The key point
For acne scars, laser resurfacing and microneedling are not competing one-size-fits-all treatments. Laser resurfacing may be considered when fractional resurfacing and a more intensive skin-renewal approach are appropriate. SkinPen microneedling may be considered when controlled collagen stimulation, a shorter visible recovery period, and a progressive course of treatment suit the scar pattern and skin assessment.
The right discussion starts with understanding your individual scars, skin characteristics, recovery capacity, and realistic goals. A detailed consultation can then determine whether one of these non-surgical approaches, a structured course, or a different specialist route is the most appropriate next step.
