What Types of Scars Can a Dermatologist Treat?

What Are Some Types of Scars Treated by Dermatologists?

Dermatologists treat a wide range of scars, each with distinct characteristics:

• Acne scars

  : These may appear as small, deep pits (ice-pick scars), wider depressions (boxcar scars), or uneven, rolling skin texture. They form when inflammation from acne damages the skin and underlying tissue.

• Hypertrophic scars

  : Raised scars that stay within the boundary of the original wound. They often appear thick or firm due to excess collagen during healing.

• Keloid scars

  : Unlike hypertrophic scars, these extend beyond the original injury site and may continue to grow over time. They can sometimes cause discomfort or itching.

• Pigmented scars (post-inflammatory hyperpigmentation)

  : These appear as darkened areas after the skin heals. While not raised or indented, they can still be a cosmetic concern.

• Surgical and injury-related scars

  : These vary in size, shape and appearance depending on how the wound healed and the treatment received.

Treatment Options for Different Types of Scars

The treatment of scars depends on their type, severity and how they affect the skin. Dermatologists typically tailor treatment plans based on the specific characteristics of each scar.

• Acne and depressed scars: Microneedling, laser resurfacing (including Fractional CO2 laser), or subcision to stimulate collagen and improve skin texture
• Raised scars (hypertrophic and keloid): Corticosteroid injections, silicone-based treatments, or laser therapy to flatten and reduce redness
• Pigmented scars: Topical treatments, chemical peels, or light-based therapies such as intense pulsed light (IPL) to even out skin tone

These treatments may be used alone or in combination, depending on the individual case. The goal is to improve both the appearance and texture of the scar while maintaining overall skin health.

When to See a Dermatologist for Scar Treatment

Not all scars require medical treatment, but some may benefit from professional assessment, especially if they affect your appearance, comfort or confidence. A dermatologist can help determine whether a scar is likely to improve on its own or if targeted treatment may be more effective.

You may consider seeking medical advice if you notice:

• A scar that becomes raised, thickened, or continues to grow over time
• Indented or uneven scars that do not improve after several months
• Persistent discolouration or pigmentation that does not fade
• Symptoms such as itching, tenderness, or tightness around the scar
