Start by Identifying What the Mark Actually Is
The best treatment depends first on what the mark actually represents. Flat discoloration after acne is different from a structural scar that changes the skin's surface. A flat mark may appear darker or redder than the surrounding skin but does not create a depression or elevation. Acne scar procedures designed to change skin texture are not automatically the right answer for a color change.
Depressed acne scars are often grouped into three main types:
- Ice-pick scars are small, narrow, and deep.
- Rolling scars create an uneven, wave-like surface because bands of scar tissue lie beneath the skin.
- Boxcar scars are round or oval depressions with more clearly defined edges.
Raised scars are a separate concern. Instead of creating a depression, they form an elevated area of scar tissue. A clinician may distinguish hypertrophic scars from keloids during an examination because they do not follow the same treatment approach as depressed scars.
Some people have more than one type of mark. For example, a face may have rolling texture, individual ice-pick scars, and flat discoloration left after inflammation. In that situation, one procedure may improve only one part of the problem. The word 'best' becomes meaningful only after the main concern has been identified as discoloration, indentation, elevation, or a mixture of these.
When the diagnosis is uncertain, an in-person assessment is more useful than choosing a procedure from photographs or treatment rankings. The appearance, depth, distribution, and current activity of the acne all affect the appropriate plan.
Match the Treatment to the Acne Scar Type
Treatment matching is based on the scar's shape and underlying structure. It is not simply a matter of choosing the most advanced-sounding procedure.
Small, deep ice-pick scars may be considered for focal punch techniques. The NHS describes punch excision for mild ice-pick scars and punch grafting for very deep ice-pick scars. These approaches target selected scars rather than broadly resurfacing the entire area.
Boxcar scars may be considered for punch elevation, particularly when the individual depressions are clearly defined. Rolling scars have a different mechanism: bands of scar tissue beneath the skin contribute to the uneven surface. Subcision is a surgical treatment used for rolling scars because it separates the upper skin from the underlying scar tissue, allowing healing tissue to elevate the depression.
Laser treatment may be considered when the main concern is broader mild-to-moderate acne scarring. Ablative laser treatment removes a small area of skin, while non-ablative treatment stimulates new collagen without removing the skin surface in the same way. The choice depends on the scar pattern, skin, and treatment goals.
These categories are guides for clinical planning, not instructions for self-diagnosis. Mixed scars are common, and a plan may involve different approaches for different areas. Punch procedures target selected scars, while resurfacing may be considered after subcision to further improve the overall appearance. No single treatment is universally best because each procedure addresses a different pattern of scarring.

Compare the Main Treatments for Indented Scars
Laser resurfacing, dermabrasion, punch techniques, and subcision differ in what they target and how much treatment burden they may involve.
Laser resurfacing treats the skin surface or stimulates collagen, depending on whether the approach is ablative or non-ablative. Ablative treatment removes a small area of skin and therefore involves surface healing. Non-ablative treatment does not remove the skin surface in the same way, but it is still an energy-based procedure that requires professional assessment. Laser treatment may be considered for broader mild-to-moderate scarring rather than a single isolated depression.
Dermabrasion removes the upper layer of skin to resurface the area. It can improve the appearance of acne scars, but healing may be substantial: the treated skin can remain red and sore for several months. This makes recovery burden an important part of the decision, rather than an afterthought.
Punch techniques are focal procedures. Punch excision, elevation, and grafting are used for selected scars, with the particular approach depending on the scar's appearance and depth. They are therefore different from treatments intended to resurface a wider area.
Subcision works beneath the skin. It releases the scar tissue contributing to rolling scars, rather than primarily removing the surface. It is not a general solution for every type of indentation.
Microneedling, radiofrequency, fillers, peels, and combination approaches may also be discussed with a qualified clinician, but they should not be treated as categorically superior without directly applicable comparative evidence. The relevant comparison is not only expected improvement; it also includes invasiveness, healing, pigment-related concerns, and the possibility that more than one type of treatment may be considered.
Understand Treatment for Raised Acne Scars
Raised acne scars require a different assessment from depressed scars. Ice-pick, rolling, and boxcar treatments are designed around indentations or tethering beneath the skin. They should not automatically be applied to an elevated scar.
A raised scar may be described as hypertrophic or keloid. These terms refer to different clinical patterns, and distinguishing between them is part of the assessment. The location, behavior, appearance, and history of the scar can help a qualified clinician determine which category is more likely.
A procedure intended to remove or remodel depressed skin may not address the biology of a raised scar and could be unsuitable. A raised area should therefore be examined before choosing resurfacing, punch treatment, subcision, or another procedure.
Assessment is particularly important when the mark continues to enlarge, extends beyond the original acne site, is painful or itchy, or is difficult to classify from its appearance alone. The appropriate plan depends on the diagnosis, not on whether a treatment is commonly promoted for 'acne scars' in general.
People with both raised and depressed scars may need separate decisions for different areas. A clinician may address the raised scars and the indented scars as distinct problems rather than treating the entire face with one method.
Choose Based on Skin, Downtime, Risk, and Goals
A suitable treatment plan considers more than the scar category. Before an invasive or energy-based procedure, discuss the following with a qualified clinician:
- the exact scar types and whether active acne is still present;
- your skin tone and how your skin has responded to previous injuries or procedures;
- relevant medical history and any factors that could affect healing;
- the amount of downtime you can accept;
- your budget and willingness to consider repeat or staged care;
- whether your priority is improving a few deep scars, broader texture, or overall appearance;
- how much uncertainty you are comfortable accepting about the result.
Recovery varies by procedure and by the individual. Dermabrasion illustrates why this matters: the NHS notes that treated skin can remain red and sore for several months while healing. That burden may be acceptable to one person and impractical for another. A less extensive procedure may still be a poor choice if it does not match the scar pattern or the person's goals.
Skin tone and previous healing history also deserve explicit discussion. The clinician can explain procedure-specific risks and whether the proposed approach is appropriate for the area being treated. When scars are mixed, raised, unusually deep, or difficult to classify, an assessment is more important than selecting a treatment based on a general ranking.
The goal should be defined clearly: improvement in selected scars, smoother overall texture, or a reduction in how noticeable the marks are. These are more realistic aims than expecting a procedure to restore completely unscarred skin.
Set Realistic Expectations for Results
Acne scar treatment can improve the appearance of scars, but it cannot be expected to remove them completely. This is true even when a procedure is appropriately matched to the scar type.
The amount of improvement depends on factors such as the scar's depth, shape, distribution, and the condition of the surrounding skin. A focal procedure may improve selected ice-pick or boxcar scars without correcting rolling texture or flat discoloration elsewhere. A resurfacing treatment aimed at broader texture should not be assumed to erase every deep or sharply defined scar.
Treatment may be individualized or staged. Punch procedures target particular scars, while additional resurfacing may be considered after subcision to further improve the overall appearance. This does not mean that combination treatment is always better; it means that different scar structures may require different approaches.
A consultation should cover the likely scope of improvement, the areas that may remain visible, the possible healing burden, and whether further care might be discussed later. Be cautious of claims promising complete removal, a guaranteed outcome, a fixed number of sessions, or one identical recovery period for everyone.
A realistic result is usually measured by reduced visibility and improved surface appearance, not by the total disappearance of the scar. Setting that expectation before treatment helps distinguish a reasonable plan from an unrealistic promise.
Prevent Further Scarring and Know When to Seek Help
Avoid picking or squeezing acne lesions. This can contribute to scarring, and severe inflammatory lesions such as nodules or cysts are more likely to damage nearby skin and leave scars. Preventing new lesions and avoiding trauma to existing ones are important while deciding whether professional treatment is needed.
Home care may be insufficient when the concern is a deep indentation, a raised scar, or a mixed pattern that is difficult to identify. A professional assessment is also appropriate when active acne continues, because new lesions can create additional scars while older ones are being treated. Do not assume that a product intended for discoloration will rebuild a deep structural scar or release scar tissue beneath the skin.
Seek advice from a suitably qualified clinician when the mark type is unclear, scars are deep or raised, or the appearance causes substantial distress. An assessment can separate flat discoloration from structural scarring and determine whether the concern is ice-pick, rolling, boxcar, raised, or mixed.
The most useful plan addresses both existing scars and ongoing acne activity. Treatment selection should follow the scar type and personal circumstances, while prevention reduces the chance of adding new scars to the areas already affected.
