How Microneedling Works: Collagen Induction Therapy

Microneedling is also called percutaneous collagen induction (PCI). A motorized pen-style device drives 9 to 36 sterile needles vertically into the stratum corneum and papillary dermis at speeds up to 8,000 rotations per minute. Each puncture forms a microscopic channel approximately 0.1 mm in diameter. The controlled micro-injury activates the three classic phases of dermal wound healing: inflammation, proliferation, and remodeling.

During the proliferation phase, fibroblasts migrate to the wound site and synthesize Type I and Type III collagen. During remodeling, Type III collagen is gradually replaced by stronger Type I collagen over 60 to 90 days. The result is measurable dermal thickening and a smoother stratum corneum, documented in peer-reviewed studies published in the Journal of Cutaneous and Aesthetic Surgery.

Clinical Benefits of Microneedling

The Microneedling Procedure at Skin Blossom Pro

A microneedling appointment at our North Vancouver clinic lasts 60 to 75 minutes. The clinical protocol follows six steps.

1. Consultation and Fitzpatrick skin typing. A medical aesthetician assesses skin type I to VI, identifies active acne, rosacea flares, or keloid history, and confirms candidacy.
2. Cleansing. The treatment area is double-cleansed with a low-pH cleanser to remove sebum and surface bacteria.
3. Topical anesthesia. A compounded lidocaine 23% / tetracaine 7% cream is applied for 20 to 30 minutes.
4. Needling pass. Depth is adjusted by zone: 0.5 mm on the forehead and eye area, 1.0 to 1.5 mm on the cheeks, and up to 2.0 mm on acne-scarred regions.
5. Serum infusion. A sterile hyaluronic acid or peptide serum is pressed into the open micro-channels.
6. Post-treatment occlusion. Mineral SPF 50 and a calming barrier cream are applied.

Microneedling with Radiofrequency (RF Microneedling)

Standard microneedling delivers mechanical micro-injury only. radiofrequency microneedling adds insulated needles that deliver bipolar RF energy directly into the dermis. The thermal effect remodels collagen fibers and tightens loose skin on the jawline, neck, and abdomen. RF microneedling is the stronger choice for clients over 35 addressing laxity in addition to texture, while standard microneedling remains the more cost-effective entry point for early collagen support and acne scar revision.

Downtime and Aftercare Protocol

Erythema resembling a moderate sunburn lasts 24 to 48 hours. Pinpoint bleeding during treatment resolves within minutes. Mild flaking can appear on days 3 to 5. Follow these aftercare rules for 72 hours:

• Avoid retinoids, AHAs, BHAs, and vitamin C.
• Cleanse with lukewarm water and a fragrance-free gentle cleanser.
• Apply mineral zinc oxide SPF 30+ every two hours when outdoors.
• Skip the gym, sauna, hot yoga, and chlorinated pools.
• Sleep on a fresh pillowcase to limit bacterial exposure.

Who Is a Candidate for Microneedling

Microneedling is appropriate for Fitzpatrick skin types I through VI because it generates no chromophore-targeted heat. It is contraindicated for clients with active cystic acne, herpes simplex outbreaks, keloid scarring history, active eczema or psoriasis in the treatment zone, current isotretinoin (Accutane) use within the past six months, or pregnancy.

How Many Sessions, Frequency, and Cost

A standard collagen-building course is three to six sessions spaced four to six weeks apart, matching the dermal remodeling cycle. Acne scar revision typically requires six sessions. Maintenance sessions every three to four months sustain results. Pricing depends on whether you select standard microneedling or the RF microneedling upgrade; current pricing is published on the microneedling treatment page. Many clients combine microneedling with an OxyGeneo super-facial or clinical facial for compounding results.
