Laser treatment can make your acne scars shallower and less noticeable, and the change takes months. Photos show someone else's scars and someone else's healing, so the useful question is what your skin is likely to do at each stage.
What a Before and After Photo Can Tell You
A useful pair of photos shares the same lighting, the same angle and the same distance, with no makeup and no filter. A change in any one of those can fake a result.
Look for less shadow inside each scar and for edges that sit closer to the surrounding skin. That is what smoother looks like on a scar, because a depressed scar is visible mainly through the shadow its walls cast. Flat red or brown marks left behind by acne are discoloration rather than scars, and fading them is a separate plan.
Why Does the Change Take Months?
Think of the laser as placing the order and your skin as doing the building. The laser makes a small, controlled injury, and your skin answers by producing new collagen where the scar sits. That building continues for months after the last session, which is why a photo taken the week after treatment tells you very little.
We bring active acne under control before scar work begins, so new scars stop forming while the old ones are being treated.
Your Scar Type Decides the Plan
Laser resurfacing can make certain depressed scars shallower; it does not fill them, and deep or tethered scars may improve less. At your evaluation we sort your scars by shape, because the shape decides the tool.
- Broad, shallow scars: Wide dips with soft edges (superficial boxcar scars) may respond to laser resurfacing on its own.
- Rolling scars tethered from below: A band of scar tissue anchors the skin down, so these often need a small release procedure beneath the skin alongside the laser.
- Narrow, deep pits: Deep pinpoint scars (ice pick scars) and the deeper, sharp-edged dips often need spot treatments with a strong acid or a minor surgical technique.
- Raised scars: Thickened scar tissue that rises above the skin (hypertrophic scars or keloids) needs a different approach altogether.
Most people carry more than one scar type on the same cheek, so most plans combine procedures. One treatment may target the depressed scars while microneedling works on texture or a chemical peel works on the discoloration around them.
The Timeline, Stage by Stage
- Right after: Your skin looks worse before it looks better, and that first stretch is part of the process.
- The first weeks: The surface peels or flakes as fresh skin forms underneath, and after that the treated skin feels smoother to the touch.
- Across a series: Each session builds on the last, and the change accumulates across the series.
- After the last session: New collagen keeps forming for several months after the final treatment, so improvement continues while nothing visible is happening.
Downtime runs from little visible recovery after gentler non-ablative work to one to three weeks or longer for ablative resurfacing. Redness can outlast the surface healing.
Ablative, Non-Ablative, and Fractional in Plain Terms
An ablative laser removes the surface of the skin in a fine layer, so each session produces more change and a longer recovery. A non-ablative laser heats the deeper skin and leaves the surface intact, so it works more gradually with less to see afterward.
Fractional describes the pattern the laser is delivered in rather than a third kind of laser. Either type can be delivered fractionally, treating narrow columns of skin and leaving the skin between them untouched. That untouched skin is why healing runs faster than treating the whole surface.
What Changes for Medium to Deep Skin Tones?
Laser treatment can be performed safely on medium to deep skin tones with the right device and settings. Deeper skin tones carry a higher risk of dark marks after the skin heals (post-inflammatory hyperpigmentation). For that reason we choose gentler settings, longer intervals between sessions, and sometimes a different device or a different mix of procedures.
Those choices change both the pace and how far the result goes. A plan for deeper skin often takes a smaller step per session over a longer stretch of months. We treat that pacing as protection for your skin's tone.
Before You Book
Your visit starts with a medical evaluation of your scar types, skin tone, goals, history, and the medications and skincare you use. Tell your dermatologist if you take or recently took prescription acne medication (isotretinoin). Timing depends on the procedure, and fully ablative resurfacing waits longer.
Tell us about any recent peel, laser, or other procedure, since the interval depends on its depth and whether your skin has fully healed. We defer treatment for active skin infection, open wounds, pregnancy, nursing, or an active herpes outbreak anywhere on the treatment field, including cold sores. A history of cold sores calls for preventive antiviral medication first.
Steroid pills or injections that act throughout the entire body, or a condition or medication that weakens whole-body immunity, need individualized planning. Recent sun exposure or tanning may delay your session.
Expected reactions include redness, swelling, warmth, discomfort, crusting, peeling, and temporary pigment change. Rarer problems include blistering or burns, bacterial or viral infection including cold sore reactivation, delayed healing, prolonged redness, scarring, and lasting darkening or lightening. Our laser treatments page carries the device details and the full list of conditions that rule treatment out or delay it.
Contact our office promptly if you notice any of these after a session:
- Pain, redness, warmth, or swelling that is getting worse instead of better.
- Fever or chills.
- Pus or foul-smelling drainage from the treated skin.
- New grouped blisters or cold sore symptoms.
- Significant blistering.
- Skin that is not healing on the schedule we described to you.

Questions Patients Often Ask
Do laser treatments work for acne scars?
Often, yes. Laser resurfacing can make many depressed scars shallower and less noticeable, and deep or tethered ones do better with a combination plan.
How many sessions does laser scar treatment take?
It varies. One treatment satisfies some patients, and others do better with a series planned around their scar type, the laser, and how their skin heals. We see you regularly through the series to check healing and adjust the plan.
Can laser treatment remove acne scars completely?
No. Laser treatment makes scars shallower and less noticeable rather than erasing them. The realistic goal is scars that sit closer to the surrounding skin and catch less shadow.
Is laser treatment safe for medium to deep skin tones?
Yes. Many laser treatments can be safely performed on medium to deep skin tones with the appropriate device and settings, individualized to your skin type. Those decisions shape how far the improvement goes as well as the risk of pigment change.
Does laser treatment help active acne as well as scars?
Not necessarily. Some laser and light devices treat active breakouts, and resurfacing lasers treat the scars breakouts leave behind, so the device and the plan differ.
