Acne scars are one of the most common long-term skin concerns we see at About Skin Clinic. This guide explains what causes them, the different types, and the treatment approaches our doctors use — so you can make an informed decision before booking any procedure.

Acne scars form when inflamed acne damages the collagen structure beneath the skin. As the skin heals, it can leave depressed (atrophic) scarring in the area, or in some cases raised scarring. The severity and depth of the original inflammation strongly influence whether a lasting scar develops.
Types of Acne Scars
- Icepick scars — narrow, deep, and pointed, often the hardest to treat with surface-level methods alone
- Boxcar scars — wider scars with well-defined edges, resembling a shallow box
- Rolling scars — broad scars with sloping edges caused by fibrous bands pulling the skin down from beneath
Most people have a combination of these scar types on the same area of skin, which is why an effective treatment plan often combines more than one technique rather than relying on a single method.
Treatment Options We Offer
- Subcision — releases the fibrous bands beneath rolling scars, allowing the skin to lift back to a more even surface
- TCA CROSS — a targeted chemical technique applied precisely into icepick scars to stimulate collagen remodeling
- Fractional and Pico Laser — resurfacing treatments that stimulate collagen production and improve overall skin texture
A doctor evaluates your scar type, depth, and skin condition before recommending which method — or combination of methods — is appropriate for you.
What to Expect at Your Consultation
Every treatment plan at About Skin Clinic starts with a doctor’s assessment, not a sales conversation. We believe understanding your specific scar type is essential before recommending any procedure, and we do not require large course packages to be purchased upfront.
Acne scars form when inflamed acne damages the collagen structure beneath the skin. As the skin heals, it can leave depressed (atrophic) scars or, less commonly, raised (hypertrophic) scars. The deeper the inflammation, the more likely a lasting scar will form.
The three main types of atrophic acne scars are icepick scars (narrow and deep), boxcar scars (wide with defined edges), and rolling scars (shallow with sloping edges caused by tethered bands beneath the skin). Most people have a mix of these, which is why treatment plans are often combined.
Yes. Non-surgical options such as Subcision (releasing tethered scar tissue under the skin), TCA CROSS (targeted chemical treatment for icepick scars), and Fractional or Pico laser resurfacing are commonly used, often in combination depending on scar type.
This varies significantly by scar depth, type, and individual skin response. A doctor will typically recommend a multi-session plan and reassess progress along the way rather than promising a fixed number of sessions upfront.
No. Acne scars from many years ago can still be evaluated and treated. Results vary by individual, and a doctor should assess the scar’s current characteristics before recommending a treatment plan.
Post-acne marks (red or dark marks) are changes in skin color that are usually flat and fade on their own over time. Acne scars are structural — a loss of collagen that leaves the skin’s surface uneven or pitted. Flat marks and pitted scars require different approaches.
No. A responsible approach starts with a doctor’s evaluation of your scar type before any treatment plan is proposed. About Skin Clinic does not require large upfront course purchases before your first consultation.
