Scar Reduction with Microneedling: Practical Guide for Professionals

Scarring, whether caused by acne, surgical procedures, or trauma—remains one of the most frequent concerns presented in professional skincare practice. While some scars naturally fade, others persist and impact both skin appearance and client confidence.

Microneedling has emerged as a safe, minimally invasive, and clinically supported treatment for improving the appearance of scars. By stimulating controlled dermal remodelling, microneedling can refine skin texture, reduce the depth of scars, and promote a more even complexion.

This guide provides licensed skincare professionals in Canada with a closer look at the role of microneedling in scar management.

What is Microneedling? 

Microneedling involves the use of a medical-grade device fitted with sterile, single-use cartridges to create controlled micro-injuries in the skin. These precise punctures activate the body’s natural wound-healing cascade, stimulating collagen and elastin production. Over time, this process supports dermal remodelling and improved skin texture.

Although the term “injury” may sound concerning, the treatment is well-tolerated. Most clients describe the sensation as a mild scratching or tingling. With repeated sessions, microneedling can improve skin firmness, reduce textural irregularities, and visibly diminish scar depth.

How Microneedling Improves Scars

Scars form when the skin repairs itself following injury. In some cases, collagen production becomes unbalanced, leading to depressed or raised marks. Microneedling helps regulate this process through several mechanisms:

1. Disrupting old scar tissue – Controlled needle penetration encourages the replacement of dense, disorganized scar tissue with healthier skin cells.

2. Stimulating collagen production – New collagen and elastin fill in pitted or atrophic scars, improving structural support.

3. Enhancing skin texture and tone – Beyond treating scars, microneedling promotes a smoother and more uniform complexion.

Clinical studies consistently demonstrate meaningful improvement in atrophic acne scars following serial microneedling treatments. According to the American Academy of Dermatology, microneedling is particularly effective for depressed scars, while raised or keloid scars often require alternative modalities.

Is Microneedling Suitable for Everyone?

Microneedling can be a beneficial treatment for many people, but it's not for everyone. If you are considering microneedling, ask yourself the following:

• Do you have certain skin conditions? Microneedling is not recommended for individuals with active acne, ongoing skin infections, eczema, or rosacea. This is to avoid the risk of spreading infection, worsening inflammation, or causing additional irritation to already compromised skin.
• Are you looking to target specific scars or skin issues? While microneedling can help with acne scars, fine lines, and other skin concerns, results may vary depending on your skin type and condition.
• If you're considering microneedling for post-surgery scars, it's important to wait 6 to 12 months before proceeding. Ensure the scar is flat—if it's raised or keloid, microneedling should be avoided. You may proceed after 6 months with a doctor's clearance for flat scars. Without clearance, it's best to wait a full 12 months before considering treatment.
• Are you willing to commit to multiple sessions? Microneedling often requires several treatments spaced a few weeks apart for optimal results.

It's always best to consult a dermatologist or skincare professional to ensure microneedling suits your skin type and needs.

At-Home Microneedling Devices

While microneedling is most effective when performed in a clinical setting, at-home devices have become popular for maintenance between professional treatments. These devices typically feature shorter needle lengths, focusing on enhancing product absorption and supporting surface-level rejuvenation.

Professionals should advise clients that at-home microneedling must always be performed with proper sanitisation and adherence to instructions to minimize risks of irritation or infection.

Preparing for Microneedling 

Pre-treatment protocols help ensure optimal results and safety. These steps should be included in the pre-microneedling routine:

1. Cleanse skin thoroughly to remove oils, sunscreen, and makeup
2. Hydrate in the days leading up to treatment to support elasticity.
3. Avoid retinoids, chemical exfoliants, or aggressive actives 48 hours before.
4. Sanitize all tools if using an at-home device.
5. Perform a patch test for new users to assess tolerance.
6. Avoid excessive sun exposure, heat, or exercise immediately prior to treatment.

The above steps create a strong foundation for a successful microneedling session, whether it's at home or in a clinic.

What to Expect After Microneedling

Post-treatment, the skin may appear flushed, warm, or mildly swollen, similar to a sunburn. These effects typically resolve within 24–48 hours, though dryness or flaking may continue for up to a week.

Aftercare recommendations include:

• Cleansing gently for the first 24 hours.

• Applying hyaluronic acid serum and a fragrance-free moisturiser.

• Using broad-spectrum mineral sunscreen (SPF 50+) daily.

• Avoiding makeup, exfoliants, and retinoids until the skin has recovered.

• Refraining from saunas, swimming, and strenuous exercise for 48 hours.

Enhancing Results with Complementary Treatments

To maximize the benefits of microneedling, pairing it with complementary skincare products and devices can significantly enhance results. Here are three practical recommendations:

• LED Light Therapy: Red light reduces inflammation, accelerates recovery, and stimulates collagen. Can be applied pre- or post-treatment.

• Targeted Serums: Hydrating and reparative formulations, such as hyaluronic acid or peptides, enhance absorption and optimize healing.

• RF (Radio Frequency) Devices: Used several days post-microneedling, RF can further stimulate collagen remodelling and skin tightening.

Conclusion

Microneedling is a valuable, evidence-based treatment for improving the appearance of scars, particularly atrophic acne scars. By promoting collagen production and enhancing skin remodelling, it delivers visible improvements in skin texture and overall complexion.

For best results, microneedling should be performed under professional guidance and combined with appropriate aftercare and supportive treatments. Consistency across a structured treatment plan remains the key to long-term improvement.
