Microneedling for Acne Scars in Los Angeles

Collagen Induction Therapy for Acne Scars and Scar Discoloration

Acne scars develop when inflammation damages collagen within the skin, leaving behind depressions, uneven texture, and discoloration that can persist long after acne resolves. While lasers and surgical techniques address certain scar types, microneedling has emerged as one of the most versatile and scientifically supported treatments for improving acne scars, skin inflammation, and overall skin quality.
At Kare Plastic Surgery, microneedling treatments are performed under physician supervision and integrated into comprehensive acne scar protocols designed by Dr. Raffy Karamanoukian, with evaluation and diagnosis by a board-certified dermatologist. This collaborative approach ensures both the structural and medical causes of acne scarring are addressed.
Microneedling stimulates natural collagen regeneration, improves pigmentation irregularities, and enhances skin healing — making it a cornerstone therapy for acne scar rehabilitation.

Microneedling for Acne Scars

What Is Microneedling?

Microneedling, also known as collagen induction therapy, uses sterile, ultra-fine needles to create controlled micro-injuries within the skin’s epidermis and dermis.
These microscopic channels trigger the body’s natural wound-healing response, stimulating:

• Collagen production
• Elastin formation
• Cellular turnover
• Improved skin vascularization

Unlike ablative laser resurfacing, microneedling preserves the epidermis while activating deep regenerative processes, resulting in gradual skin remodeling with minimal downtime.

Mechanism of Action — How Microneedling Improves Acne Scars

Controlled Micro-Injury and Healing Cascade

1. Platelets release growth factors.
2. Fibroblasts activate collagen synthesis.
3. New extracellular matrix forms.
4. Scar depressions gradually elevate.

This regenerative response replaces disorganized scar tissue with healthier collagen.

Collagen Types Produced

Research shows microneedling increases production of:

• Type I collagen (skin strength)
• Type III collagen (early wound healing)
• Elastin fibers (skin elasticity)

Clinical studies demonstrate significant improvement in acne scar appearance after multiple microneedling sessions, with measurable increases in dermal thickness and skin smoothness.

Skin Conditions Treated with Microneedling

At Kare Plastic Surgery, microneedling is used for more than acne scars alone.

Atrophic Acne Scars

Particularly effective for:

• Rolling scars
• Shallow boxcar scars
• Diffuse texture irregularities

Post-Inflammatory Hyperpigmentation

Microneedling accelerates epidermal turnover, helping fade dark acne marks.

Skin Inflammation and Healing

Controlled injury promotes anti-inflammatory signaling and improved skin repair.

Skin Rejuvenation

Patients experience:

• Improved tone and texture
• Smaller appearing pores
• Enhanced skin luminosity
• Increased firmness

Who Is a Good Candidate for Microneedling?

Ideal candidates include patients who have:

• Mild to moderate acne scars
• Uneven skin texture
• Acne pigmentation
• Early signs of aging
• Sensitive skin not suited for aggressive lasers

Microneedling is safe for a wide range of skin tones, including darker skin types that may carry higher risks with certain laser treatments.

Dermatologic Evaluation Matters

At Kare Plastic Surgery, a board-certified dermatologist evaluates:

• Active acne presence
• Scar morphology
• Pigmentation risk
• Underlying inflammatory conditions

Accurate diagnosis ensures microneedling is performed at appropriate depths and combined with complementary therapies when needed.

Microneedling Treatment Process

Step-by-Step Procedure

1. Skin cleansing and topical numbing
2. Controlled microneedle penetration at customized depths
3. Application of topical regenerative boosters
4. Post-treatment calming protocol

Treatment sessions typically last 30–45 minutes. Depth selection is customized depending on scar type and treatment goals.

Advanced Microneedling with Regenerative Boosters

One of the major advantages at Kare Plastic Surgery is integration of biologic enhancement therapies.

Exosomes

Exosomes contain signaling molecules that enhance cellular communication and accelerate tissue repair.
Potential benefits include:

• Faster healing
• Reduced inflammation
• Enhanced collagen stimulation

Polynucleotides

Polynucleotides promote tissue regeneration and hydration by supporting fibroblast activity and extracellular matrix repair.

Platelet-Rich Plasma (PRP)

PRP delivers concentrated growth factors derived from the patient’s own blood, amplifying collagen production.
Clinical studies suggest combining PRP with microneedling improves acne scar outcomes compared with microneedling alone.

Downtime and Recovery After Microneedling

Microneedling offers relatively minimal downtime compared to resurfacing lasers.

First 24–48 Hours

• Redness similar to mild sunburn
• Warm sensation
• Mild swelling

Days 2–4

• Light flaking or dryness
• Skin appears slightly pink

One Week

• Skin tone normalizes
• Early glow noticeable

Most patients resume normal activities within 24 hours.

Microneedling vs RF Microneedling for Acne Scars

Patients often ask about the difference between traditional microneedling and radiofrequency (RF) microneedling.

Traditional Microneedling

• Mechanical collagen stimulation
• Excellent for pigmentation and texture
• Minimal heat injury
• Short recovery time

RF Microneedling

• Combines needles with thermal energy
• Greater dermal tightening
• Stronger effect on deeper scars

Which Is Better?

  Many patients benefit from staged combination therapy.

Evidence-Based Outcomes of Microneedling

Multiple clinical studies support microneedling for acne scar improvement.
Research demonstrates:

• Significant reduction in scar severity scores
• Increased dermal collagen deposition
• High patient satisfaction
• Improvement after 3–6 sessions

Studies comparing microneedling with fractional lasers show comparable improvement for moderate acne scars with fewer adverse effects.

Typical Treatment Course

• 3–6 sessions
• Spaced 4–6 weeks apart
• Progressive cumulative improvement

Collagen remodeling continues for several months after the final treatment.

Why Dr. Raffy Karamanoukian Is an Expert in Microneedling Treatments

Successful microneedling depends heavily on physician technique, depth control, and treatment planning.
Dr. Raffy Karamanoukian integrates microneedling within comprehensive acne scar rehabilitation programs, combining:

• Customized needle depths
• Regenerative boosters (exosomes, PRP, polynucleotides)
• Acne inflammation control
• Combination laser and surgical treatments

His expertise in facial anatomy and scar biology allows treatments tailored to individual scar patterns rather than standardized protocols. This physician-directed strategy improves both safety and long-term outcomes.

Importance of Dermatologist Supervision

Acne scars frequently coexist with active inflammatory acne or rosacea.
A board-certified dermatologist at Kare Plastic Surgery provides:

• Microneedling + Subcision
• Microneedling + Vbeam laser
• Microneedling + PRP

Treating inflammation and vascular redness first often enhances collagen response.

Frequently Asked Questions (FAQs)

Does Microneedling really work for acne scars? 

Microneedling is an amazing treatment that helps improve skin quality through a mechanism known as collagen induction therapy in which small micro-injuries are made in the skin to stimulate cell renewal. For acne scars, SkinPen brand microneedling allows for resurfacing of skin hyperpigmentation and discoloration, as well as improvement in atrophic acne scars that involve superficial contour depressions. Microneedling has limited efficacy in ice-pick scar treatment, but is clinically indicated for boxcar and valley scars on the face. In our Santa Monica office, we use microneedling combined with exosomes and PRP, as well as combination microneedling with fractional laser, chemical peels, TCA Cross, and subcision. 

How many sessions of Microneedling do you need for acne scars? 

Most patients require a series of three to six microneedling sessions to achieve meaningful improvement in acne scars, although the exact number depends on how severe the scars are and how the skin responds to treatment. Clinicians first evaluate the type and depth of acne scars, including rolling, boxcar, or early ice-pick scars, since deeper collagen loss requires more treatment cycles to stimulate adequate dermal remodeling. Mild scars may improve after a few sessions, while moderate to severe scarring often benefits from extended treatment plans combined with other technologies.

Modern protocols frequently enhance microneedling with platelet-rich plasma (PRP) or exosome therapy, which deliver growth factors that accelerate healing and amplify collagen production. Providers may also alternate or combine microneedling with fractional laser treatments to target deeper tissue layers and improve overall skin texture. By adjusting treatment intervals, biologic enhancements, and laser integration, clinicians create a customized plan that maximizes collagen regeneration while minimizing downtime and inflammation for optimal acne scar improvement.

Can microneedling worsen acne?

When active acne is medically controlled and treatment is physician-guided, risk is low.

Does microneedling help pigmentation?

Yes. Increased cell turnover improves post-inflammatory hyperpigmentation.

Are results permanent?

New collagen formation is permanent, though aging and new acne can influence skin over time.

Is microneedling safe for darker skin tones?

Microneedling is one of the safest resurfacing treatments for higher Fitzpatrick skin types.

Expected Results Timeline

Results develop gradually as collagen rebuilds naturally.
