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.
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.
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.
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 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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
