Micro needling, also known as collagen induction therapy, is a minimally invasive cosmetic treatment used to rejuvenate the skin. It works by creating tiny punctures in the skin using a device with fine needles. These micro-injuries stimulate the body’s natural wound-healing process, encouraging collagen and elastin production.
But does it actually work for acne scars?
Let’s break down the facts, benefits, treatment process, and results of micro needling backed by data and professional opinions from experts like those at Medica Estetica.
How Acne Scars Form
Acne scars are formed when inflammation damages the skin’s deeper layers. Common types include:
- Ice pick scars deep and narrow
- Boxcar scars wide, with sharp edges
- Rolling scars shallow with sloping edges
These scars are usually resistant to topical treatments. That’s where micro needling comes in as a deeper, collagen-focused treatment.
How Micro Needling Helps Acne Scars
Micro needling works by:
- Stimulating Collagen: Triggers collagen and elastin production which fills in depressed scars.
- Improving Skin Texture: Encourages regeneration of smoother, healthier skin layers.
- Enhancing Absorption: Post-treatment, your skin becomes more receptive to serums (e.g., hyaluronic acid or vitamin C).
- Minimal Downtime: Unlike lasers, it has less downtime and lower risk for hyperpigmentation in darker skin tones.
The Micro Needling Procedure (Step-by-Step)
At clinics like Medica Estetica, this is how the process typically works:
Step 1: Skin Assessment
A professional examines your acne scars to determine suitability and customize your treatment plan.
Step 2: Cleansing & Numbing
Your skin is cleaned thoroughly and a numbing cream is applied for comfort.
Step 3: The Needling Process
A micro needling pen or roller is used over the targeted areas. Tiny needles create microchannels in the skin.
Step 4: Post-Treatment Serum
A serum like hyaluronic acid is applied to aid in healing and maximize results.
Step 5: Aftercare
Sunscreen and moisturizing instructions are provided. Redness and light flaking are normal for 1–3 days.
How Many Sessions Are Needed?
While results vary, 3 to 6 sessions spaced 4–6 weeks apart are commonly recommended for moderate acne scarring. Deep scars may require more.
What Results Can You Expect?
- Improvement Timeline: Noticeable texture improvements begin after 3–4 weeks
- Full Results: Best seen after the final session (around 3–6 months)
- Before & After: Many users report 50%–80% scar reduction after 4–6 treatments
From Medica Estetica, patients often report smoother, firmer skin with visibly reduced scar depth and better skin tone.
Clinical Data Supporting Micro Needling
A study in the Journal of Cutaneous and Aesthetic Surgery showed:
- 80% of patients with acne scars rated their results as “excellent” or “good”
- Minimal adverse effects
- Better results when combined with vitamin C or PRP (Platelet-Rich Plasma)
Another study comparing micro needling vs. laser showed similar results, but with less downtime and fewer side effects for micro needling.
Micro Needling vs. Other Treatments
| Treatment | Downtime | Skin Type Suitability | Effectiveness for Scars |
| Micro Needling | Low (1–3 days) | All skin types | Moderate to High |
| Chemical Peels | Moderate | Fair to medium tones | Mild to moderate |
| Laser Resurfacing | High (1–2 weeks) | Light skin preferred | High |
| Dermal Fillers | None | All | Temporary improvement |
Who Should Avoid Micro Needling?
Micro needling is not suitable for people who:
- Have active acne or skin infections
- Are pregnant or breastfeeding
- Have keloid scars or poor wound healing history
- Use certain medications like isotretinoin
Always consult a certified provider for a proper assessment.
