What Is Fractional CO2 Resurfacing?

Introduction to Skin Resurfacing Treatments

Skin resurfacing has become one of the most sought-after cosmetic procedures today. As people look for fast, effective, and non-surgical ways to rejuvenate the skin, advanced laser treatments have taken center stage. From fine lines to acne scars, technology now makes it possible to dramatically improve skin quality without going under the knife.

Traditional treatments like dermabrasion and deep chemical peels once dominated the industry, but they came with long downtime and discomfort. That’s where modern fractional resurfacing steps in—offering the same dramatic results with far less recovery.

Understanding Fractional CO2 Resurfacing

Fractional CO2 resurfacing is a next-generation laser treatment designed to repair damaged skin and boost natural collagen. But what exactly makes it “fractional”?

What “Fractional” Really Means

Instead of removing the entire surface of the skin, the laser creates thousands of tiny, controlled micro-injuries known as microthermal zones. These zones trigger rapid healing, leaving the surrounding healthy skin untouched to support recovery. This means better results with less downtime.

The Science Behind CO2 Laser Technology

CO2 lasers use a wavelength of 10,600 nm, which effectively targets water molecules within the skin. When the laser energy hits the tissue, it vaporizes damaged cells and stimulates deep dermal remodeling. In simple terms? It renews your skin from the inside out.

How Fractional CO2 Laser Works

Microthermal Zones Explained

Think of the treatment like aerating a lawn—only selected microscopic patches are targeted, allowing the skin around them to speed up healing.

Collagen Stimulation and Skin Regeneration

As the skin repairs itself, fibroblast activity increases and new collagen forms. This helps tighten, refresh, and renew the skin for months after treatment.

What Fractional CO2 Resurfacing Treats

Fine Lines and Deep Wrinkles

Around the eyes, mouth, and forehead.
