Treating Atrophic Acne Scars with MicroNeedling
For individuals with atrophic acne scars, pitted facial scars are a constant reminder of past skin issues that often negatively affect their quality of life. Studies suggest that those with atrophic acne scars usually have a negative self-image, with many frequently being self-conscious and living in fear of the scars never going away.
Of the many treatment options available, one that has shown success is microneedling, a minimally invasive cosmetic procedure involving tiny sterile needles that induce a cascade of processes associated with the body’s natural healing response.
Offering this aesthetic procedure to individuals with atrophic acne scars will significantly help improve their overall well-being. This article will provide an overview of the microneedling process, helping you understand the mechanism of action and protocol
How Microneedling Improves the Appearance of Atrophic Acne Scars
Microneedling creates controlled microscopic wounds in the skin, which triggers the body’s natural healing cascade.
Among these processes is the stimulation of collagen and elastin production. These two essential proteins are crucial for healthy, youthful-looking skin. Growth factor release improves appearance by facilitating improved blood flow and more efficient inflammatory response.
The micro-injuries help break down the scar tissue associated with atrophic acne scars, instigating the skin’s remodeling process, which smoothes out the appearance of indented blemishes. Over multiple sessions, the skin’s texture and overall appearance can dramatically improve, leaving patients with a more even, radiant complexion.
One of the critical advantages of microneedling is its ability to target the deeper layers of the epidermis where the scar tissue resides. This targeted approach sets microneedling apart from other scar-reducing treatments, which may only address surface-level concerns.
Recommended Protocol Per Microneedling Session
Microneedling is a variable procedure dependent on the practitioner’s abilities and the patient’s requirements. However, Alster and Graham (2017) from the American Society for Dermatologic Surgery, Inc. provided evidence-based recommendations per microneedling session to ensure the best possible outcomes.
These recommendations are summarized as follows:
Clinical Assessment and Pre-Procedure Guidance
Thoroughly evaluate the patient’s skin type, condition, and scar severity to determine the appropriate needle depth and treatment approach. Provide detailed pre-treatment instructions, such as avoiding certain skincare products or medications that could increase sensitivity. Ensure that patients with a history of oral herpes take a course of oral antivirals before the treatment as a preventive measure against possible viral reactivation.
Determine the procedure’s suitability to avoid adverse reactions; while microneedling is generally well-tolerated, some patients may exhibit complications when undergoing the procedure, such as a local infection or immunosuppression.
Skin Cleansing and Application of Topical Anesthesia
Using a gentle cleanser, thoroughly cleanse the treatment area to remove dirt, oil, or makeup. Apply a topical anesthetic cream, typically a compounded 20/10/10 BLT cream (non-occluded), for 20 to 30 minutes, allowing the area to numb before the procedure.
Proper Treatment
Properly prepare the microneedling device by ensuring it is clean and a sterile needle cartridge is installed correctly. Adjust the needle depth based on the patient’s skin type and scar severity, typically 0.5 to 2.0 mm.
Segment the treatment area into quadrants to ensure maximum coverage, and utilize either the Gentle Skin Traction Technique or the “Rocking” or “Stamping” Technique to treat the atrophic acne scars effectively. You may also use the pinpoint bleeding to determine which areas have already been treated.
● Gentle Skin Traction Technique: Gentle traction delicately stretches the skin while positioning the microneedling device at a 90-degree angle, facilitating the creation of even micro-channels that enhance product absorption and promote an intensified healing response for superior skin rejuvenation.
● “Rocking” or “Stamping” Technique: The “rocking” or “stamping” technique entails pressing the microneedling device perpendicularly into the skin and then lifting it back and forth, allowing for more focused and deeper needle penetration, which is particularly effective in addressing deeper wrinkles and scars compared to the continuous gliding motion of gentle traction.
Post-Procedure Regimen
Provide detailed aftercare instructions, including soothing, hydrating products and sun protection. Advise the patient to expect mild redness, swelling, and peeling in the following days, which are regular and temporary side effects.
Efficacy and Safety Profile of Microneedling for Atrophic Acne Scars
Numerous clinical studies have demonstrated the remarkable efficacy of microneedling in improving the appearance of atrophic acne scars.
Sitohang et al. (2021) performed a systematic review assessing the efficacy of microneedling (MN) as a treatment for atrophic acne scars, highlighting effectiveness in both monotherapy and combination therapies across nine randomized controlled trials.
Their study has shown consistent improvement in scar appearance, whether as a monotherapy or combined with other treatments, with no significant adverse effects reported. They emphasized the need for further research with larger sample sizes and extended follow-up to validate these findings.
Furthermore, microneedling is generally considered a safe and well-tolerated procedure when performed by a trained and experienced provider. The most common side effects, such as temporary redness, swelling, and mild discomfort, typically resolve within a few days. Serious complications, such as infection, scarring, or post-inflammatory hyperpigmentation, are rare when adhering to proper safety protocols.
What is the correct number of Microneedling Sessions?
Optimal results for atrophic acne scars vary depending on the patient’s skin condition and scar severity. General advice is a series of 3 to 6 treatments, spaced apart by 4 to 6 weeks.
It is important to note that some patients may require additional sessions or a more extended treatment interval to achieve their desired outcome. Ensure you work closely with your patients to monitor their progress; adjust the treatment plan for quality results.
Many providers utilize semi-annual booster treatments to maintain a refreshed look.
