Acne scars don't fade on their own, but several treatments can reduce how visible they are

Acne scars are permanent changes to your skin texture or depth. Unlike red marks left by active acne, which fade over months, true scars involve loss of collagen or pitting that your skin cannot repair without intervention. The good news is that multiple treatments exist—some over-the-counter, some requiring a dermatologist—and they work differently depending on what type of scar you have.

The type of scar matters enormously. Atrophic scars are indented or pitted (the most common type). Hypertrophic scars are raised and thick. Boxcar scars are broad and flat-bottomed. Rolling scars have sloped edges. Ice pick scars are narrow and deep. A dermatologist can identify which you have and recommend treatments that actually work for that specific scar type, because a treatment effective for one type may do nothing for another.

Key Takeaways

  • Atrophic (indented) scars are the most common type and respond best to treatments that rebuild collagen or resurface skin, such as laser therapy or microneedling.
  • Over-the-counter products like retinoids and vitamin C may reduce the appearance of very shallow scars but cannot fill deep pits or indentations.
  • Professional treatments—laser resurfacing, chemical peels, microneedling, dermal fillers, and subcision—produce visible results but vary in cost, recovery time, and how long results last.
  • Combination treatment (using two or more methods together) often works better than a single treatment, especially for severe scarring.
  • A dermatologist can examine your scars in person and recommend the most effective option for your skin type and scar depth.

Over-the-counter products and what they can and cannot do

Retinoids (vitamin A derivatives) and vitamin C serums are the only over-the-counter ingredients with evidence that they may reduce the appearance of shallow scars. Retinoids increase cell turnover and can thicken skin over time, which may make very minor surface irregularities less noticeable. Vitamin C is an antioxidant that supports collagen production. Neither ingredient, however, can fill a deep pit or indentation—they work only on texture and very shallow scarring.

Silicone-based scar creams and ointments are heavily marketed but have limited evidence. They may soften the appearance of raised scars (hypertrophic or keloid scars) by hydrating the area, but they do not reduce indented scars. Sunscreen is essential if you use any of these products, because sun exposure can darken scars and make them more visible.

If your scars are deep, broad, or numerous, over-the-counter products alone will not produce noticeable change. They are a reasonable starting point for very mild scarring or while you are researching professional options, but they have real limits.

Laser treatments and how they work on different scar types

Laser resurfacing removes the outer layer of skin and stimulates collagen remodeling underneath. Ablative lasers (such as CO2 and erbium lasers) vaporize the skin surface and produce the most dramatic results, especially for atrophic scars. Non-ablative lasers (such as fractional lasers and pulsed dye lasers) heat the deeper skin layers without removing the surface, so recovery is faster but results are more gradual and may require multiple sessions.

Laser works best on atrophic scars because it resurfacing the skin and triggering new collagen formation fills in indentations over time. It is less effective on raised scars (hypertrophic) and does not work well on very deep ice pick scars. Recovery from ablative laser can take two to three weeks, with significant redness and peeling. Non-ablative laser recovery is shorter—a few days to a week—but you may need four to six sessions spaced weeks apart.

Laser can also treat the redness of scars. Pulsed dye lasers target blood vessels and can fade the pink or purple color of newer scars, making them blend better with surrounding skin even if the texture does not change.

Microneedling, chemical peels, and subcision

Microneedling uses tiny needles to create controlled micro-injuries in the skin, triggering collagen production and remodeling. It works on atrophic scars and is gentler than laser resurfacing, with less downtime—usually just redness for a day or two. Results appear gradually over several months as collagen rebuilds, and most people need three to six sessions spaced four to six weeks apart. It is less effective on very deep scars and does not work on raised scars.

Chemical peels use acids to remove the outer skin layer and stimulate collagen. Superficial peels (using glycolic or salicylic acid) have minimal downtime but produce subtle results and work only on very shallow scars. Medium and deep peels produce more dramatic results but require longer recovery and carry higher risk of complications, including permanent lightening of the skin. Chemical peels work best on atrophic scars with mild to moderate depth.

Subcision is a surgical technique where a needle is inserted under a scar to break the fibrous bands pulling the skin down, allowing it to rise. It works specifically on rolling scars and atrophic scars with sloped edges. It is often combined with other treatments like laser or microneedling for better results. Recovery is minimal—some bruising for a few days—but results take weeks to months to fully appear as the skin remodels.

Dermal fillers for temporary scar improvement

Dermal fillers (hyaluronic acid, calcium hydroxylapatite, or other materials) are injected under indented scars to raise them level with surrounding skin. Results are immediate and visible, but fillers are temporary—they break down over months to years depending on the type. Hyaluronic acid fillers typically last three to six months. Calcium hydroxylapatite lasts longer, often nine to twelve months.

Fillers work well for atrophic scars and are a good option if you want to see results before committing to permanent treatments. They carry minimal downtime and low risk. The main drawback is cost and the need for repeat treatments to maintain results. Some people use fillers while pursuing longer-term treatments like laser or microneedling.

Combination treatment and what to expect from results

Many dermatologists recommend combining treatments because scars respond better to multiple approaches. For example, subcision followed by laser resurfacing, or microneedling combined with a chemical peel, often produces better results than either treatment alone. Combination treatment addresses different aspects of the scar—depth, texture, color, and collagen remodeling—simultaneously.

Results from any scar treatment take time. Laser and microneedling require weeks to months for collagen to rebuild and scars to fade noticeably. Chemical peels show results sooner but may need repetition. Fillers show immediate results but are temporary. Most people see meaningful improvement after one to three months, with continued improvement for six to twelve months as collagen remodels.

Realistic expectations matter. No treatment erases scars completely, especially deep or severe ones. The goal is to reduce how visible they are—making indentations shallower, softening edges, and evening out skin texture. Mild to moderate scars often respond well and become barely noticeable. Severe scarring may improve significantly but remain somewhat visible.

Cost, recovery time, and choosing between options

Over-the-counter products cost $20 to $60 and carry no recovery time. Professional treatments vary widely: chemical peels range from $150 to $3,000 depending on depth; microneedling typically costs $200 to $700 per session; laser resurfacing ranges from $1,000 to $5,000 per session; dermal fillers cost $400 to $1,000 per syringe; subcision costs $500 to $2,000. Most insurance does not cover scar treatments because they are considered cosmetic.

Recovery time also varies. Microneedling and subcision have minimal downtime. Non-ablative laser has a few days of redness. Ablative laser requires one to three weeks of significant peeling and redness. Chemical peels range from no downtime (superficial) to two to three weeks (deep). Dermal fillers have no downtime.

Choosing between options depends on your scar type, how deep the scars are, how much downtime you can tolerate, your budget, and how quickly you want to see results. A dermatologist can examine your scars and recommend the most effective treatment or combination for your specific situation. Many offer consultations to discuss options before you commit.

Frequently Asked Questions

Can acne scars go away on their own?

No. True acne scars involve permanent loss of collagen or changes to skin structure. Red or brown marks left by acne fade naturally over months, but indented or raised scars do not improve without treatment. The earlier you treat scars, the better they often respond, so waiting does not help.

Which treatment works best for ice pick scars?

Ice pick scars are narrow and very deep, making them the hardest to treat. Laser resurfacing, subcision combined with laser, or punch excision (surgical removal of the scar) are the most effective options. Microneedling and chemical peels are less effective because the scars are too deep. A dermatologist can assess whether your ice pick scars are candidates for treatment.

How many laser sessions do I need?

Non-ablative laser typically requires four to six sessions spaced four to six weeks apart. Ablative laser often produces significant results in one to three sessions because it is more aggressive. Results continue improving for months after treatment as collagen rebuilds. Your dermatologist can estimate how many sessions your scars will need based on depth and severity.

Will my scars come back after treatment?

No. Treatments that work by resurfacing skin or rebuilding collagen produce permanent improvement. Dermal fillers are the exception—they are temporary and fade over months to years, so you would need repeat injections to maintain results. Laser, microneedling, chemical peels, and subcision produce lasting change.

Can I treat acne scars if I have darker skin?

Yes, but some treatments carry higher risk of complications like permanent lightening or darkening of the skin. Non-ablative laser, microneedling, and subcision are generally safer for darker skin tones than ablative laser and deep chemical peels. A dermatologist experienced in treating darker skin can recommend the safest and most effective options for you.
