Laser treatment for acne scars
When the pits and marks left behind by acne make you shy away from bright light and the mirror, this approach helps your skin look smoother and more even over a course of sessions, so you see a fresher version of your own skin that still looks like you.
Is this right for you?
Acne scars are the changes that remain in your skin after inflamed breakouts have healed. They can be depressions in many shapes - narrow, deep ice-pick scars, sharply defined boxcar scars, and gently sloping rolling scars - or, less often, raised scars that sit above the skin. A laser is a beam of light at a selected wavelength that delivers energy into the skin to remove or heat very small areas, prompting the skin to build new collagen and remodel the surface over time. Many of today's devices work in a fractional pattern, treating tiny points scattered between areas of untouched skin, which helps recovery move faster. Whether this suits you depends a great deal on the type of scar, how deep it is, and the nature of your skin. Here is how to tell.
This may be a good fit if
- Your main concern is pitted scars, depressed scars, or uneven skin texture left behind once your acne has settled.
- Your acne is now under control, with no active inflammatory flare-ups in the area you want treated.
- You understand that improvement comes gradually over a course of several sessions, and you accept some downtime after each session while your skin recovers.
- You can protect yourself carefully from the sun and wear sunscreen every day, both before and after treatment, because skin is very sensitive to sunlight after laser.
- You hold realistic expectations: the aim is to soften scars and make the surface more even, not to erase every mark.
This may not be right if
- You currently have active inflammatory acne, an open wound, or a skin infection in the area you want treated - it is usually wise to settle this first.
- You have a tendency to form raised (keloid) scars or to develop pigment changes after inflammation - laser can make these worse, so it needs very careful thought.
- You are pregnant or breastfeeding, or you have recently taken certain oral acne medications.
- You expect your scars to be gone after a single session, or you want your skin to look exactly like a photo you bring in.
How it works
Everything starts with a consultation. Your doctor listens to what you hope for, examines your skin, and assesses the type of scar, how shallow or deep it is, the texture, your skin tone, and how sensitive your skin is. This step matters, because each kind of scar responds to laser differently, and some deeper scars may need to be combined with another method. Your doctor also asks about your acne history, your tendency to scar, and the medications and products you use, and then agrees with you on the type of laser, the likely number of sessions, and the spacing between them.
Before the session, your skin is cleansed and a numbing cream is usually applied to the surface to keep you more comfortable; for some deeper techniques, your doctor may use another form of pain relief. How much numbing is needed depends on the type of laser and the size of the area being treated. You and the person performing the treatment both wear eye protection throughout, because laser light can harm the eyes.
During treatment, your doctor moves the laser handpiece across the scarred area in passes. The beam creates tiny points of action, removing or heating very small parts of the skin to prompt healing and the growth of new collagen, so the scarred surface remodels over time. You may feel something like the snap of a rubber band and a warm, tingling sensation on the skin. A session usually takes a few tens of minutes, depending on the area.
Laser treatment for acne scars almost always needs a course of several sessions, spaced a few weeks to a few months apart, so the skin can recover and collagen can rebuild between visits. After each session, your doctor reviews how your skin responded and adjusts the settings for the next one, rather than following a fixed recipe. The exact number of sessions depends on the type and severity of your scars.
Realistic expectations
This approach works toward a smoother, more even skin surface, with pitted and depressed scars softening over each session as the skin rebuilds collagen. Improvement is gradual and builds up over time, and it is usually clearer once the full course is complete. How much your skin responds varies from person to person, depending on the type of scar, how deep it is, and the nature of your skin.
What this will not do
- It will not erase every scar in a single session - improvement comes gradually over the course and needs time for collagen to rebuild.
- It will not stop new breakouts or new scars from forming later if your acne is not yet under control.
- It will not whiten your skin or change your natural skin tone; the aim is a more even, smoother surface that still looks natural, not bleaching.
- It is not a substitute for treating active acne, protecting against the sun, and daily skin care - these remain essential.
Recovery
What happens after laser scar treatment varies quite a bit with the type of laser: lighter, more surface-level techniques usually cause only mild redness for a few days, while deeper techniques need more downtime and the skin flakes more noticeably. How you care for your skin afterward plays a large part in the result. The points below are rough guides - everyone, and every type of laser, moves at a different pace.
- Right after the session
- The treated area is usually flushed, warm, and a little swollen, much like the feeling after a lot of sun. Your skin is soothed, you are shown how to moisturise, and you can usually go home the same day.
- The first few days
- Your skin may darken slightly, feel rough, and then flake away like a fine layer of scale. You avoid picking or scratching, keep the skin clean, and moisturise as your doctor directs. With deeper techniques, this is the stage that needs more downtime.
- Around 1 to 2 weeks
- The redness and flaking usually settle, and the treated area begins to look smoother and more even. The new skin is still delicate, so you keep protecting it carefully from the sun.
- Between sessions (a few weeks to a few months)
- Collagen rebuilds gradually over this time, and the improvement in texture builds up across the course. You rest between visits on the schedule your doctor sets, so your skin recovers before the next session.
- After the full course
- A clearer result is usually seen once the whole course is finished and the skin has had more time to settle; your doctor arranges a review and discusses maintenance sessions if needed.
Risks & safety
Most cases done by sound principles go smoothly. But any treatment that acts on the skin carries risks worth knowing in advance, and with laser scar treatment some risks tie directly to your skin tone, your tendency to scar, and sun protection. Your doctor will talk these through with you.
- Redness, swelling, stinging, or roughness in the treated area that lasts longer than expected.
- Post-inflammatory hyperpigmentation - the treated skin darkens for a time, which is more common in deeper skin tones and with sun exposure.
- Loss of pigment - the area becomes lighter than the surrounding skin, sometimes for a long time.
- Blistering, raw areas, and, more rarely, the formation of new scars or raised (keloid) scars, especially in people prone to keloids.
- A flare of cold sores in people with a history of herpes around the lips or mouth.
- Infection in the treated area if it is not cared for properly.
- An uneven result, or less improvement than you hoped for, needing more sessions than first expected - with deep scars, improvement can be limited.
How we do it
The hard part of treating acne scars is not firing the laser; it is choosing the right person to treat and the right type of laser for each kind of scar. At The Gioi Dep, before anything begins, our doctors examine and classify your scars, assess your skin type and your tendency to scar, and tell you plainly whether laser truly suits you, then choose the technique and settings to match. If your acne is still active or you are prone to keloid scars, we say so directly and discuss a way forward first, rather than rushing to treat a surface that is not yet stable.
When laser is a sound choice, our doctors build the course around how your skin responds, reviewing after each session and adjusting the settings to fit. You are given clear guidance on caring for your skin, protecting against the sun, and what to avoid between sessions - an important part of holding the result and lowering the chance of darkening or new scars - along with an honest conversation about how much improvement is realistic. You can always reach back out if your skin reacts unexpectedly or anything is worrying you.
Frequently asked questions
Does laser treatment for acne scars hurt?
The treated area is usually numbed with a cream beforehand to keep you more comfortable, and with deeper techniques your doctor may use another form of pain relief. Many people describe it as the snap of a rubber band and a warm tingle on the skin during treatment. How much discomfort you feel depends on the type of laser and the size of the area.
How many sessions will I need?
Laser treatment for acne scars almost always needs a course of several sessions, spaced a few weeks to a few months apart, so the skin can recover and collagen can rebuild. The exact number depends on the type and severity of your scars, and your doctor will make a plan for you after examining your skin.
How much time off will I need?
Downtime depends on the type of laser: lighter, surface-level techniques usually cause only mild redness for a few days and you return to your routine fairly quickly, while deeper techniques need more time off because the skin flakes more noticeably. Your doctor will talk this through in advance so you can plan your work around it.
Will the result look natural?
Yes. This approach works toward a smoother, more even surface in a gradual way, not an obvious change. Your skin becomes smoother and scars soften over each session as collagen rebuilds, so the result usually looks very natural. How much it improves varies with the type of scar and the nature of your skin.
Will laser remove all of my scars?
The realistic aim is to soften scars and make the surface more even, not to erase every mark. Shallower scars tend to respond better; with deep scars such as narrow ice-pick scars, improvement can be limited and may sometimes need to be combined with another method. Your doctor will discuss this honestly after examining your skin.
Can I have this done while I still have acne?
If you currently have active inflammatory acne or a skin infection in the area you want treated, it is usually wise to wait until the acne settles before treating the scars. Treating skin that is not yet stable can raise the risks. Your doctor will examine you and advise on the right time, which sometimes means treating the acne first.
My skin is darker - what if it darkens after treatment?
Deeper skin tones can be treated, but the risk of post-inflammatory hyperpigmentation is higher, meaning the treated area darkens for a time, especially with sun exposure. For that reason your doctor chooses the type of laser and settings carefully, sometimes leaning toward a gentler technique. The darkening usually fades over time; careful sun protection helps limit it, and you should tell your doctor so you can be followed up.
Could I be left with new scars?
Forming new scars is a rare risk when treatment follows sound principles and the skin is cared for properly, but it is higher in people prone to keloid scars. That is why your doctor needs to know your scarring history beforehand. Avoiding picking or scratching the flaking skin, keeping it clean, and following the guidance all help lower this risk.
Why do I still need to protect carefully against the sun after treatment?
Skin is very sensitive to sunlight after laser, and the sun prompts the skin to make more pigment, which can easily darken the area you have just treated. Wearing sunscreen every day and shielding yourself from the sun is an essential part of holding the result and lowering the chance of darkening.
How long does the result last?
The scars that have been remodelled are usually stable, but your skin keeps ageing, and new breakouts and scars can still appear if your acne is not under control. Your doctor will usually arrange a review and may suggest maintenance sessions, along with keeping up your acne treatment and skin care.
