How Er:YAG 2940 Laser can help with acne scarring
Many people researching acne scarring compare Er:YAG (erbium) laser with CO2 fractional laser, since both are ablative resurfacing options but behave differently on the skin.
Quick answer
Er:YAG 2940 laser is another resurfacing option considered for acne scarring at Naomi Waite Aesthetics, alongside CO2 laser and RF microneedling. Its wavelength allows a different balance of precision and depth, which can suit certain scarring patterns and skin types. Whether it, or another approach, fits your scarring best is confirmed at consultation.
How Er:YAG 2940 Laser works on acne scarring
Acne scarring can range from shallow, widespread textural change to more defined depressions, and the pattern you have affects which resurfacing approach makes sense. Er:YAG's water absorption allows a more controlled, layer-by-layer style of resurfacing, which some practitioners favour for finer textural irregularity or where a different depth of ablation is wanted compared with CO2.
For the underlying mechanism, see our Er:YAG 2940 laser treatment page. For acne scarring, what matters is less the wavelength itself and more how your scarring pattern, skin tone and healing history line up with an ablative approach generally, which is assessed at consultation.
Who Er:YAG 2940 Laser suits for acne scarring (and when another option may fit better)
Er:YAG is often considered by people who want ablative resurfacing but whose practitioner feels a different depth or precision profile to CO2 suits their scarring or skin better. It's frequently discussed as an alternative within the same resurfacing category rather than a completely different approach.
It may fit less well where non-ablative options such as RF microneedling are preferred, for example due to downtime preferences or skin tone considerations, or where scarring is shallow enough that microneedling alone may be appropriate. This is worked through individually at consultation, sometimes supported by our skin scanner assessment.
What a course looks like at Naomi Waite Aesthetics
As with any resurfacing plan for acne scarring, a course starts with an assessment of your scarring pattern, skin type and acne history, since active breakouts can affect timing. Your plan is built around your scarring rather than a standard protocol.
Where scarring sits alongside other concerns, such as enlarged pores or textural dullness, your practitioner may suggest combining Er:YAG resurfacing with other steps in your skincare routine. Specific numbers of sessions and intervals are confirmed once your skin has been assessed.
Er:YAG 2940 Laser compared with other options for acne scarring
Er:YAG sits alongside CO2 laser, RF microneedling, microneedling, plasma skin tightening and medical microdermabrasion as a way of addressing acne scarring, each suited to different scarring patterns and preferences around downtime. We help you weigh these up for your own scarring at consultation.
Aftercare after Er:YAG 2940 Laser for acne scarring
General aftercare for Er:YAG resurfacing is covered on our treatment page. For acne-prone skin specifically, it's worth being extra mindful of keeping the treated area clean while it heals, and holding off on any new active skincare products until your practitioner confirms it's fine to reintroduce them.
If breakouts appear during healing, let your practitioner know rather than trying to manage this yourself, since acne-prone, healing skin needs a slightly different approach to ordinary blemishes. Daily sun protection remains important while scarred skin recovers and settles.

Frequently asked questions
Er:YAG laser is a recognised resurfacing option that some people use to help improve the appearance of textured acne scarring, though individual results vary and it cannot guarantee a specific outcome or remove scarring completely. Whether it suits your scarring is assessed at consultation.
The right number of sessions depends on your scarring pattern, skin and how it responds to treatment, so this isn't something we can state generally. Your practitioner will talk through a realistic plan once your scarring has been assessed.
Suitability is assessed individually, taking into account your skin tone, medical history and the specific pattern of your acne scarring. As with any ablative resurfacing, this needs an in-person consultation rather than a general answer.
General comfort and sensation during Er:YAG treatment are covered on our treatment page. Previously scarred or thinner areas of skin can feel slightly different during treatment, which your practitioner will explain before starting.
Skin continues to remodel for some time after resurfacing, so changes in scarring texture tend to become more visible gradually rather than immediately. Your practitioner can give you a realistic timeframe based on your own scarring at consultation.
Both are ablative resurfacing lasers, and neither is universally better for acne scarring; they offer a different balance of depth and precision. We compare them against your specific scarring pattern and skin at consultation.
