The Wound Healing Response: Why Microneedling Works

The Wound Healing Response: Why Microneedling Works

Understanding the science behind real skin transformation

Microneedling is more than a trendy treatment. When performed correctly, it taps into your body’s natural ability to heal—and that’s where the real transformation begins.

The results aren’t from the tiny injuries themselves, but from how your skin responds to them. Microneedling stimulates your own collagen production through a multi-phase process known as the wound healing cascade.

🔬 The Three Phases of Healing

1. Inflammation Phase (Days 1–3): What’s Really Happening

Immediately after microneedling, your skin’s built-in repair system is activated. The microchannels created by the needles don’t cause damage—they signal the body to send help. That help arrives fast.

What’s happening below the surface:

• Hemostasis:
  Platelets rush to the microchannels to form clots and stop any minor pinpoint bleeding. These platelets release growth factors (like PDGF and TGF-β), which act as signals to initiate healing.

• Vasodilation & Immune Response:
  Blood vessels widen, allowing immune cells—like neutrophils and macrophages—to flood the area. These cells remove debris, fight off any pathogens, and release more healing messengers.

• Fibroblast Recruitment Begins:
  Fibroblasts, the cells responsible for producing new collagen and elastin, start migrating toward the area. Their big moment comes in the next phase, but the foundation is already being laid.

What you might feel:

• Redness (like a sunburn)

• Warmth or mild heat

• Tightness, puffiness, or sensitivity

• Slight flaking or dryness as early cell turnover begins

All of this is normal. Proper post-care (hydration, calming serums, barrier protection, and avoiding heat or sweat) helps guide the skin into the next phase of healing.

2. Proliferation (Days 4–14)

This is when your skin really gets to work.

• Fibroblasts are actively producing new collagen and elastin

• Blood vessels (angiogenesis) are forming to support fresh tissue

• Keratinocytes restore the epidermal barrier and improve skin texture

Most people begin to see subtle firmness or clarity return here. It’s happening from within—no filter needed.

3. Remodeling (Weeks 2–8 and beyond)

This is where your skin becomes stronger and more resilient.

• Type III collagen from the proliferation phase is replaced by stronger Type I collagen

• Skin becomes firmer, smoother, and better supported

• Scars and texture begin to visibly improve

This is why microneedling results don’t peak right away—they unfold over time.

🕒 Timing Matters

Microneedling isn’t about instant gratification—it’s about supporting your skin’s biology. Sessions are typically spaced 4–6 weeks apart to allow full healing and maximize results.

Stacking sessions too close together can interrupt this process and lead to surface irritation instead of deeper change.

✨ Real Results Come from Within

Microneedling respects your skin’s integrity. With the right depth, spacing, technique, and aftercare, it gently encourages your skin to regenerate itself—not by forcing change, but by stimulating your own biology.

📦 Growth Factors: Amplifying the Healing Response

At Glow, clinical microneedling includes the infusion of human growth factors—bio-identical proteins that support the skin’s natural regeneration process. When applied during or immediately after needling, growth factors help:

• Accelerate the healing cascade

• Reduce downtime and inflammation

• Promote stronger collagen and elastin production

• Enhance overall skin quality and texture

They’re most effective when used at the right time—while the microchannels are still open—allowing direct delivery into the skin’s deeper layers.

💧 Aftercare: Protect the Glow You Just Stimulated

What you do after your treatment is just as important as the treatment itself. Proper aftercare supports healing, reduces irritation, and helps lock in results.

Here's what I recommend:

• Avoid heat, sweat, and sun exposure for the first 24–48 hours

• Stick with calming, hydrating products (no actives, acids, or retinol for at least 5 days)

• Use barrier-repair creams or balms to soothe and protect

• Apply mineral SPF daily, especially as your skin becomes more photosensitive

• Stay hydrated, rest, and trust the process—the glow will come

At Glow, you’ll receive personalized product guidance and post-treatment support to ensure your skin stays nourished, protected, and supported through every phase of healing.
