Post-Acne Scarring: What It Is and How We Can Treat It

Written by Nurse Richele

If you’ve struggled with acne, you’ll know that sometimes the breakouts are only half the battle. Long after the inflammation settles, many people are left dealing with post-acne scarring, something that can impact confidence just as much as active acne.

The good news? There are effective, evidence-based treatments available, and with the right approach, significant improvement is absolutely achievable.

What Causes Acne Scarring?

Acne scars form when inflammation penetrates deeply into the skin and damages the underlying tissue. As the skin tries to repair itself, it produces collagen, but not always evenly. This can result in either:

• Depressed scars (atrophic): Indented areas caused by collagen loss

• Raised scars (hypertrophic or keloid): Excess collagen forming thicker tissue

• Post-inflammatory pigmentation: Flat dark or red marks left after healing (not true scars, but still a concern)

Understanding the type of scarring is essential, as this determines the most effective treatment plan.

Types of Acne Scars

Not all acne scars are the same. The most common include:

• Ice pick scars: Deep, narrow scars that extend into the dermis

• Boxcar scars: Broad depressions with defined edges

• Rolling scars: Wave-like indentations due to fibrous bands under the skin

• Hypertrophic scars: Raised, firm scars often found on the chest or back

Each type responds differently to treatment, which is why a personalised approach is key.

Treatment Options for Post-Acne Scarring

There’s no one-size-fits-all solution, but here are some of the most effective treatments we use in clinic:

1. Skin Needling (Microneedling)

A highly effective treatment that stimulates collagen production by creating controlled micro-injuries in the skin.

Best for: Rolling and boxcar scars
Benefits: Improves texture, minimal downtime, gradual natural results

2. Chemical Peels

Medical-grade peels exfoliate the skin and encourage regeneration.

Best for: Superficial scarring and pigmentation
Benefits: Brightens skin, improves tone and mild texture irregularities

We use Mesoestetic professional products in the clinic, with the Mesopeel range specifically designed to target acne, pigmentation, and uneven texture using combinations of AHAs and BHAs to stimulate cell renewal and improve skin clarity. 

3. Laser Treatments

Advanced laser technology targets deeper layers of the skin to remodel collagen.

Best for: Moderate to severe scarring
Benefits: Significant improvement in texture and depth of scars

4. Mesoestetic Professional Skincare

Targeted, medical-grade homecare is essential to support in-clinic treatments and optimise results. I often prescribe specific Mesoestetic products tailored to each client’s skin concerns:

• Cosmelan Protocol
  A gold-standard depigmenting system that helps reduce post-inflammatory pigmentation and uneven skin tone. 

• Melan Tran3x Concentrate & Gel Cream
  Advanced brightening formulas that target stubborn pigmentation using tranexamic acid derivatives to reduce dark spots and improve overall clarity. 

• Blemiderm Treatment & Resurfacing Gel
  Designed specifically for acne-prone and post-acne skin to regulate oil, refine pores, and support skin renewal. 

• Mesoprotech Melan 130 Pigment Control SPF 50+
  Daily sun protection is critical to prevent worsening pigmentation and protect treatment results. 

What Results Can You Expect?

It’s important to set realistic expectations, acne scarring can be significantly improved, but not always completely erased. Most clients require a series of treatments, and results build over time as collagen production increases.

Consistency, patience, and the right combination of treatments are key.

Why Professional Assessment Matters

Every skin journey is different. What works for one person may not work for another, and treating acne scars incorrectly can sometimes worsen the condition.

That’s why I always recommend a thorough skin consultation. Together, we can assess your skin, identify your scar type, and create a tailored treatment plan that aligns with your goals and lifestyle.

Post-acne scarring doesn’t have to be permanent. With modern aesthetic treatments and a personalised approach, smoother, clearer skin is within reach.
