Understanding Acne Scars: Types, Causes, and Effective Treatments

Acne affects millions of people worldwide, and its aftermath can be just as frustrating as the breakouts themselves. Acne scars come in various forms, each with unique characteristics that require tailored treatments. In this article, we’ll delve into the different types of acne scars, their causes, and the most effective ways to address them.

The Prevalence of Acne Scars

Acne is a common skin condition that affects 40 to 54 percent of adults, making it a more widespread issue than you might think. While some people may be comfortable with their skin texture, others may want to minimize the appearance of acne scars. Fortunately, there are better treatment options available today than ever before.

Why Do Acne Scars Form?

Acne scars result from damage to the skin following repeated inflammation from acne cysts. Even if you resist the temptation to pop or mess with your acne, your skin can still scar. The depth of the breakout determines the severity of the scar, with shallow lesions usually healing quickly and leaving little to no scarring, while deeper lesions spread to nearby tissue, causing a more pronounced scar.

Types of Acne Scars

There are several types of acne scars, each with distinct characteristics. The first three types are called “atrophic” because they’re depressions in the skin.

• Ice Pick Scars: Narrow, deep indentations common in the cheeks, resembling a scar made from a tiny ice pick.
• Boxcar Scars: Wider depressions in the skin with more defined edges, similar to chicken pox scars.
• Rolling Scars: The widest of the atrophic scars, with varying depths, curved edges, and an irregular look.

Treatment Options for Atrophic Acne Scars

Addressing atrophic scars usually involves reducing the depth of the scar and then treating any discoloration. Treatment options range from mild to clinical-level and include:

• Chemical peels
• Laser resurfacing
• Dermabrasion
• Dermal fillers
• Microneedling
• Punch excision
• Punch grafting
• Subcision
• TCA CROSS peels

Hypertrophic and Keloid Scars

Instead of indentations, hypertrophic scars are raised up from the skin due to excessive collagen production during healing. These are less common and mostly associated with body acne.

• Hypertrophic Scars: Raised scars the same size as the acne that caused them.
• Keloid Scars: Larger than the original spot, often resulting from excessive collagen production.

Treatment Options for Hypertrophic Acne Scars

Treatment for raised scars focuses on reducing the height of the scar. Options include:

• Laser resurfacing
• Steroid injections
• Surgical removal
• Over-the-counter (OTC) scar treatments like silicone sheets or oils

Post-Inflammatory Hyperpigmentation

Acne inflammation can leave behind a signature: extra pigment from the skin producing extra melanin during healing. This is especially common in those with darker skin tones.

Treatment Options for Post-Inflammatory Hyperpigmentation

Consistent use of SPF 30+ sunscreen is key, along with other treatments like:

• OTC or prescription-level topical treatments like vitamin C, azelaic acid, and retinoids
• Chemical peels
• Laser resurfacing

Seeking Professional Help

If your scars are bothering you, working with a dermatologist is the most effective way to tackle your skin texture. Your treatment plan depends on the type of scars you have, and while treatments can be costly and take time to start working, knowing what to expect can help you make informed decisions.
