Acne scars are broadly categorised into pitted (atrophic) and raised (hypertrophic) types, each requiring different approaches. Understanding your scar type is the first step towards effective treatment.
Types of acne scars
Pitted scars (atrophic)
Pitted scars are the most common and occur when the skin doesn’t produce enough collagen during healing. They include:
- Ice pick scars: Deep, narrow, and V-shaped.
- Boxcar scars: Wider, U-shaped with defined edges.
- Rolling scars: Broad depressions with sloping edges.
Raised scars (hypertrophic)
Raised scars form when the skin produces too much collagen during healing. They include:
- Hypertrophic scars: Raised but remain within the original wound area.
- Keloid scars: Extend beyond the original wound and can grow over time.
Practical takeaway
Identifying your scar type helps you research treatments effectively. Consult a dermatologist for personalised advice if you’re unsure. For more information on acne scars, visit American Academy of Dermatology.
