The Science of Percutaneous Collagen Induction: Maximizing Results with Post-Treatment Skincare
Microneedling, scientifically referred to as Percutaneous Collagen Induction (PCI) or skin needling, has transitioned from a niche dermatological procedure to a cornerstone of regenerative aesthetics. At Richmond Anti-Aging Clinic (RAAC) in Richmond, BC, we approach this treatment not merely as a cosmetic service, but as a precise biological intervention designed to leverage the body’s innate wound-healing cascade.
Understanding the biochemical pathways activated during a session is essential for any patient considering this journey. Furthermore, the efficacy of the procedure is profoundly influenced by the post-treatment skincare regimen adopted during the critical healing window. Learn more about Microneedling and how it can transform your skin texture and tone.
The Mechanism of Action: Cellular and Biochemical Pathways
Microneedling operates on the principle of controlled physical trauma. By utilizing medical-grade, oscillating micro-needles, the procedure creates thousands of microscopic "channels" in the stratum corneum and dermis. These micro-channels serve two primary functions: the mechanical stimulation of fibroblasts and the creation of a temporary delivery system for topical agents.
The Three Phases of Wound Healing
- Inflammation Phase: Immediately following the creation of micro-injuries, platelets are activated, releasing chemotactic factors that include Platelet-Derived Growth Factor (PDGF) and Transforming Growth Factor-beta (TGF-β). This initial surge triggers the migration of neutrophils and monocytes.
- Proliferative Phase: Fibroblasts, the primary cells responsible for collagen production, migrate to the site of injury. These cells begin synthesizing new extracellular matrix (ECM) components, including Type III collagen, elastin, and glycosaminoglycans.
- Remodeling Phase: Over several months, the initial Type III collagen is replaced by more organized, stronger Type I collagen. This process, often called collagen induction, results in skin tightening and the reduction of scar tissue.
At Richmond Anti-Aging Clinic (RAAC), we emphasize that the success of this biological cascade depends heavily on the health of the patient's skin and the precision of the device used. Book a Consultation to have your skin health assessed by our medical team.
Clinical Evidence: What the Research Says
The efficacy of microneedling is well-documented in peer-reviewed literature. When evaluating the procedure, it is important to look at the clinical data that supports its use for various indications:
- Aust et al., Plastic and Reconstructive Surgery: This seminal study demonstrated that microneedling leads to a significant increase in collagen and elastin deposition. Histological examinations showed a 140% increase in epidermal thickness and a dramatic upregulation of growth factors.
- Fabbrocini et al., Journal of Dermatological Treatment: Researchers found that microneedling is an exceptionally effective and safe treatment for atrophic acne scars. The study highlighted that the procedure maintains the integrity of the epidermis, which reduces the risk of post-inflammatory hyperpigmentation compared to ablative lasers.
- Hou et al., Dermatologic Surgery: This study explored the synergistic effects of microneedling and topical delivery. It confirmed that the micro-channels created during treatment significantly enhance the penetration of therapeutic molecules, underscoring why specific post-treatment skincare is vital for the best outcomes.
Candidate Evaluation and Physician Oversight
While microneedling is versatile, it is not a "one-size-fits-all" treatment. At RAAC, every patient undergoes a rigorous candidate evaluation. This process is overseen by Dr. Charles Jiang, a CPSBC-registered physician with over 29 years of clinical experience.
Dr. Jiang ensures that patients are screened for contraindications such as active acne, keloidal tendencies, or the use of certain systemic medications. Under his guidance, our clinic in Richmond ensures that the depth of the needles and the intensity of the treatment are customized to the patient’s Fitzpatrick skin type and specific concerns. This physician-led approach is what differentiates RAAC from non-medical spas, ensuring both safety and clinical efficacy.
The Critical Window: Why Post-Treatment Skincare Matters
The micro-channels created during skin needling remain open for a limited time—typically between 4 to 24 hours. This is known as the "channel window." During this time, the skin’s barrier function is temporarily compromised, making it both highly receptive to beneficial ingredients and vulnerable to irritants.
Your post-treatment skincare should focus on three pillars:
- Hydration: Hyaluronic acid is the gold standard during the first 24 hours to support cellular migration.
- Protection: Avoiding UV exposure and using non-chemical, mineral-based sunscreens once the channels have closed.
- Avoidance of Actives: Patients must pause the use of retinoids, Vitamin C (L-ascorbic acid), and exfoliating acids for 3-5 days to prevent granulomas or excessive inflammation.
Many of our clients in Richmond have found that adhering strictly to our prescribed medical-grade aftercare significantly reduces downtime and accelerates the appearance of their results.

Limitations and Contraindications
While microneedling is highly effective for texture, fine lines, and scarring, it has limitations. It may not be the primary choice for significant skin laxity or deep dynamic wrinkles, where treatments like dermal fillers or radiofrequency-assisted needling might be more appropriate.
Contraindications include:
- Active skin infections or herpes simplex in the treatment area.
- History of hypertrophic or keloid scarring.
- Recent use of Isotretinoin (within the last 6 months).
- Scleroderma or collagen vascular diseases.
Frequently Asked Questions
How many sessions are typically required?
Most clinical studies and our own experience at RAAC suggest a series of 3 to 6 treatments, spaced 4 to 6 weeks apart, to achieve significant collagen induction.
Is the procedure painful?
We apply a high-potency topical numbing cream prior to the procedure. Most patients describe the sensation as a light sandpaper-like feeling or a mild vibration.
What should I expect during recovery?
Immediately after, the skin will appear similar to a moderate sunburn. Most redness subsides within 24 to 48 hours. Following our specific post-treatment skincare advice is essential during this time.
How much does microneedling cost?
Costs vary based on the area treated and whether growth factors or other serums are integrated. Contact us for current pricing and to discuss our package options.
