# Dermabrasion for Acne Scars: Indications, Limits, and Recovery > An educational guide to dermabrasion for acne scars: scar types, pigment risks, preparation, wound care and why no treatment erases every scar. - Author and medical reviewer: Dr. Walter Zamarian Jr. — CRM-PR 17.388 | RQE 15.688 - Published: 2026-02-19 - Updated: 2026-10-24 - Language: en - Canonical HTML page: https://www.walterzamarianjr.com/blog/dermabrasion-acne-scars-indications-recovery/ - Topics: dermoabrasao ## At a glance Surgical dermabrasion can soften the edges and surface irregularities of selected, shallower acne scars. Narrow, deep scars or depressions tethered to tissue underneath usually require a different approach, sometimes as part of a combined plan. The aim is to make scars less noticeable, not erase them. In this educational article, I explain why scar depth, active acne, pigmentation, and healing history matter. Recovery involves wound care, follow-up, and sun protection; infection, pigment changes, and additional scarring are possible. In my current practice, I use [dermabrasion only for scar revision](https://www.walterzamarianjr.com/us/face/dermabrasion/), not for acne or acne scars. This article explains its use for acne scars in the medical literature; it does not describe a treatment I offer for that indication. The comparisons with lasers, fillers, and chemical peels are also educational, and I do not offer those aesthetic treatments. Describing how a treatment works is not an individual recommendation. ## Start with the scar, not the device Acne scars are three-dimensional. A mark may involve an uneven surface, deeper attachments pulling the skin downward, a loss of volume, or a combination of these. That is why a single resurfacing treatment cannot be assumed to address every scar on a face. I find it more useful to explain which part of a scar a technique can change than to start with a percentage of improvement. A procedure that softens an edge may do little for a deep attachment beneath it. Someone can also have several scar types in the same area, which makes classification especially important. ### Ice-pick scars These are narrow, deep depressions. Their depth limits what superficial resurfacing alone can achieve. Focal treatments such as TCA CROSS or punch excision may be discussed before a broader surface treatment. This is a description of treatment options, not a recommendation to use acids or perform any procedure yourself. ### Boxcar scars Boxcar scars have more defined edges and relatively flat bases. Shallower or moderately deep examples may be suitable for dermabrasion because smoothing the transition between the edge and surrounding skin can make the depression less conspicuous. Depth still matters: the name alone does not determine suitability. ### Rolling scars Rolling scars create a wavy or undulating surface. Fibrous bands beneath the skin may be pulling it downward. Subcision can be considered to release those attachments. Smoothing the surface without addressing an underlying tether may leave the depression largely unchanged. ### Raised scars Hypertrophic scars are raised rather than depressed. They require a different treatment strategy. Aggressive dermabrasion in someone prone to hypertrophic scars or keloids can worsen the problem. A history of raised scars is therefore important before discussing resurfacing. ## What surgical dermabrasion does Dermabrasion is mechanical resurfacing: an abrasive instrument removes superficial layers in a controlled way, and healing changes the surface texture. It is different from superficial cosmetic microdermabrasion. Surgical dermabrasion requires preparation, an anesthetic plan, dressings, and medical follow-up. Its purpose is to soften edges and reduce uneven transitions between a scar and the adjacent skin. It does not create completely unscarred skin or turn every deep depression into a smooth surface. Appropriate depth and selection are central to the balance between improvement and complications. The [review of non-energy-based acne-scar treatments](https://pmc.ncbi.nlm.nih.gov/articles/PMC8963193/) describes why scar morphology influences the choice of treatment. I use that same distinction throughout this explanation: surface texture, deeper attachments, and volume loss are different problems. ## Where dermabrasion may fit in a treatment plan In the medical literature, dermabrasion is considered for selected superficial or moderately deep boxcar scars and areas of uneven texture. It may also be used after focal procedures such as punch excision, punch elevation, or subcision to help blend remaining edges. Those combinations address different components. Subcision releases tethering. Punch excision removes an individual deep scar. Punch elevation raises a selected depressed area. Resurfacing can then address the surface, when indicated. If volume loss contributes to the appearance, [facial fat grafting](https://deepplanefaceliftbrazil.com/surgery/facial-fat-grafting/) may be discussed in a combined plan, but restoring volume does not replace treatment of the skin surface. Equally, a surface treatment does not necessarily restore deeper support. Not everyone needs multiple procedures. The point is to identify the reason for each step and allow healing and reassessment between stages when appropriate. ## Reasons to postpone or reconsider treatment Active inflammatory acne, infection, or an active herpes outbreak can make resurfacing inappropriate at that time. Recent tanning, unstable melasma, a tendency to form keloids, and an inability to protect the skin from the sun also affect the decision. Current or recent isotretinoin use needs an individual discussion. The type and extent of dermabrasion matter; a single waiting period should not be applied indiscriminately to every procedure. Do not stop prescribed medication on your own. Medication decisions belong with the clinician responsible for the treatment. Other medicines and health factors can influence healing. Anticoagulants, immunosuppressants, corticosteroids, a history of herpes, and recent skin treatments need to be reviewed. Assessing a scar without considering the rest of the person’s medical history misses part of the risk. ## Skin tone and pigment changes Skin with more pigment can be more susceptible to post-inflammatory darkening and, in some circumstances, lighter patches after treatment. A higher phototype is not a reason to ignore the concern, but it can change the depth, preparation, alternatives, and follow-up that are appropriate. Melasma and a history of discoloration after irritation also matter. A treatment that improves texture but leaves a persistent color difference may create a new concern. Sun protection and careful planning are therefore part of the treatment itself, not optional additions afterward. The objective is to improve a particular scar problem while respecting the way that person’s skin heals. More aggressive treatment is not automatically a better choice. ## Preparation is individualized Preparation may involve controlling active acne, reviewing irritating skin products, protecting the skin from sunlight, and discussing medications. A clinician may consider antiviral prevention for someone with a history of herpes or pigment-control treatment in selected cases. These are examples of the issues addressed during planning, rather than a prescription for readers to follow. The examination, medical history, and intended depth determine what is relevant. A photograph can help a discussion, but it does not replace an in-person assessment of texture, depth, and attachments. An assessment also considers how the scars are distributed. Cheeks, temples, the jawline, and the area around the mouth have different skin characteristics. Oiliness, pores, visible small vessels, pigmentation, and sensitivity can all influence the plan. ## Why acne should be controlled first Active inflammatory acne can increase the risk of infection, ongoing inflammation, new scars, and post-inflammatory pigment changes. Resurfacing existing marks does not address an active process that is continuing to create new lesions. A staged approach may therefore begin with dermatological care to stabilize the acne. Only then is it useful to reassess the scars and decide which features need treatment. In some people, preparation takes months. The appropriate sequence follows the condition of the skin rather than a desired treatment date. ## Dermabrasion compared with other approaches Lasers and chemical peels act differently from mechanical dermabrasion. Selected laser treatments may address texture and certain scars; chemical peels can address superficial texture and pigmentation, while focal TCA CROSS is directed at narrow, deep scars. Subcision and punch techniques are different again because they address structural features rather than simply smoothing the surface. A comparison is only meaningful when it specifies the scar type, the intended change, and the risks. I do not treat the availability of a technology as evidence that it is needed. Lasers, peels, and fillers mentioned here remain educational comparisons, not services offered in my current practice. Any proposed combination should have a clear purpose and a realistic account of what it cannot change. ## What recovery involves Redness, tenderness, moisture or oozing from the treated surface, and crusting can occur after medical dermabrasion. New surface skin forms progressively, and redness may remain for weeks. Healing time and the duration of visible redness vary. Local wound care and sun protection are important throughout recovery. Picking crusts, applying unapproved products, swimming, exposing the area to sunlight, or missing follow-up visits can interfere with care. The treating team should provide instructions suited to the procedure and review how the skin is progressing. Increasing pain, discharge, fever, blisters suggestive of herpes, sudden worsening of redness, or other signs of infection require prompt contact with the treating clinician. If the team cannot be reached, seek in-person medical care. Those symptoms should not be managed by waiting for a cosmetic result to settle. ## What improvement can realistically mean No treatment reliably removes every acne scar. A responsible goal is to reduce unevenness, soften edges, improve texture, and make individual marks less apparent. The degree of improvement varies with anatomy, skin characteristics, and healing. The [systematic review of acne-scar treatments](https://pmc.ncbi.nlm.nih.gov/articles/PMC5965325/) discusses multiple approaches rather than a single solution for all scars. That is a useful way to frame expectations. A tethered rolling scar may still look depressed after its surface improves; a deep ice-pick scar may remain visible while the surrounding texture becomes smoother. Assessment over time helps distinguish healing changes from the result. Standardized photographs and an examination can support a decision about whether any later stage is worthwhile. A plan should allow reassessment instead of promising a predetermined sequence for everyone. ## Questions to bring to an assessment Ask which scar types are present, which feature each proposed technique is meant to address, and how pigment or raised-scar risks apply to your skin. It is also worth discussing the wound-care routine, follow-up arrangements, and reasons a procedure might need to be postponed. The most useful question is often: “What part of my scar can this treatment change?” An answer that separates the surface, attachments, and volume gives a clearer basis for a decision than a universal percentage or a promise of flawless skin. ## Sources and further reading - [Mayo Clinic: dermabrasion](https://www.mayoclinic.org/tests-procedures/dermabrasion/about/pac-20393764). - [American Society of Plastic Surgeons: dermabrasion risks and safety](https://www.plasticsurgery.org/cosmetic-procedures/dermabrasion/safety). - [Cleveland Clinic: dermabrasion](https://my.clevelandclinic.org/health/treatments/8309-dermabrasion). - [NCBI Bookshelf: skin resurfacing dermabrasion](https://www.ncbi.nlm.nih.gov/books/NBK558955/). - [Non-energy-based treatments for atrophic acne scarring](https://pmc.ncbi.nlm.nih.gov/articles/PMC8963193/). - [Systematic review of treatments for acne scarring](https://pmc.ncbi.nlm.nih.gov/articles/PMC5965325/). --- Medical information for educational purposes.
