Acne scar treatment options: what works for each scar
Acne can leave two very different things behind: flat marks that change the colour of the skin, and true scars that change its texture. They need different treatments, and most real improvement comes from matching the treatment to the scar type and combining options over time. This guide explains the main types and what usually helps each one.
Step one: marks or scars?
Post-inflammatory hyperpigmentation (PIH) is a flat brown or dark mark left after a spot. It is very common in medium and darker skin. It is not a scar, and it usually fades well with treatment and sun protection.
Post-inflammatory erythema (PIE) is a flat red or pink mark. It is also not a true scar and usually fades over time.
True acne scars change the surface of the skin. Most are indented (atrophic), and a few are raised:
- Rolling scars: broad, shallow, wavy depressions, caused by bands of tissue pulling the skin down.
- Boxcar scars: round or oval depressions with sharp edges, shallow or deep.
- Ice-pick scars: narrow, deep pits, like large open pores.
- Raised scars (hypertrophic or keloid): thick, firm scars, more common on the jaw, chest and back.
Most people have a mix of types, which is why a mix of treatments usually works best.
First rule: control active acne
Scar treatments usually start once active acne is under control. Resurfacing inflamed skin can spread irritation, raise the risk of dark marks and waste sessions while new scars are still forming. See Acne treatment.
Options for dark and red marks
- Chemical peels to lift surface pigment and even tone.
- Laser toning on a Q-switched laser such as the Lutronic Spectra, for selected pigment.
- Medical skincare with pigment-reducing ingredients, plus daily sunscreen, which is essential in Cairo's sun.
These are all available at NeoDerma. See Pigmentation and melasma.
Options for indented scars
Fractional CO2 laser (available at NeoDerma)
Fractional CO2 is one of the most effective treatments for rolling and boxcar scars. It creates microscopic treated columns in the skin that trigger new collagen, gradually smoothing texture. NeoDerma uses the Lutronic eCO2 and Deka DOT.
- Usually: a series of about 3 to 5 sessions, 4 to 8 weeks apart.
- Downtime: usually about a week of redness and flaking.
- Results: build over 3 to 6 months as collagen forms.
- Darker skin: needs conservative settings, skin preparation and strict sun protection to reduce the risk of temporary darkening.
See Fractional CO2.
Fillers for rolling scars (where suitable)
Hyaluronic acid fillers can lift some broad, soft rolling scars by restoring volume beneath them. The effect is temporary and does not suit every scar. NeoDerma uses Teosyal fillers; the doctor will tell you if your scars are suitable.
Chemical peels
Superficial peels mainly help marks and overall texture rather than deep scars, but they are a useful part of a combined plan. See Chemical peels.
Other options a dermatologist may discuss
These are well-established scar treatments in dermatology. They are listed for completeness; ask the clinic whether they are part of your plan.
- Subcision: a needle releases the bands of tissue that pull rolling scars down.
- Microneedling and radiofrequency microneedling: fine needles stimulate collagen, with less downtime than ablative lasers.
- TCA CROSS: a high-strength acid placed precisely into individual ice-pick scars.
- Steroid injections: for raised (hypertrophic or keloid) scars.
Matching treatment to scar type
| Scar type | Usually helps most |
|---|---|
| Dark marks (PIH) | Peels, laser toning, medical skincare, sunscreen |
| Red marks (PIE) | Time, gentle care, sometimes vascular laser |
| Rolling scars | Fractional CO2, subcision, fillers |
| Boxcar scars | Fractional CO2, sometimes combined with other options |
| Ice-pick scars | TCA CROSS, sometimes punch techniques, plus resurfacing |
| Raised scars | Steroid injections and other specialist treatments |
What to expect from a scar plan
- It takes time. Scar plans usually run over several months, with results building as collagen remodels.
- Combination works best. Most people need more than one technique.
- Improvement, not perfection. Scars rarely disappear completely, but they can usually be softened in a clearly visible way.
- Protect the result. Daily sunscreen, no picking and keeping acne under control all matter.
Frequently asked questions
What is the best treatment for acne scars?
There is no single best treatment. Fractional CO2 is one of the most effective for rolling and boxcar scars, and most plans combine it with other techniques depending on scar type.
Are dark marks after acne scars?
No. Flat dark or red marks are not true scars and usually fade with peels, laser toning, skincare and sun protection.
How many sessions do acne scars need?
It varies with scar type and depth. Fractional CO2 usually needs around 3 to 5 sessions, often combined with other treatments.
Can acne scars be removed completely?
Scars rarely disappear completely, but they can usually be improved significantly.
Can I treat scars while I still have acne?
Usually active acne is controlled first. Gentle treatment for marks can sometimes start earlier.
Is fractional CO2 safe for brown skin?
It can be, with careful settings, preparation and strict sun protection, because darker skin has a higher risk of temporary pigmentation.
