Fractional CO₂ laser applied in gynecology is clinically proven to reverse degenerative vaginal tissue changes. Vaginal tissue degeneration mainly comes from three root causes: natural aging, menopause and childbirth.

• Aging: Gradual loss of collagen and elastin reduces mucosal thickness and tissue elasticity.
• Menopause: Declined level leads to genitourinary syndrome of menopause (GSM), including mucosal atrophy, dryness, burning and dyspareunia.
• Postpartum: Vaginal connective tissues are stretched and fractured during delivery, resulting in laxity and weakened supportive structure.

With fractional microablative technology, controlled micro thermal columns trigger natural tissue remodeling. New collagen and elastin are synthesized to thicken vaginal mucosa and restore elasticity, improving vaginal atrophy, dryness, laxity and related symptoms. It is a non-surgical option for female intimate rejuvenation.

How Fractional CO₂ Laser Combines with Tattoo Removal

Picosecond or Q-switched laser is the primary workhorse to shatter tattoo ink particles. Fractional CO₂ laser serves as an adjuvant therapy instead of breaking pigment directly. There are two mainstream clinical combination protocols.

1. Staged Sequential Treatment (Most widely used & safer)

1. Perform picosecond / Q-switched laser first to fragment tattoo pigment.
2. Wait for full skin re-epithelialization (2–4 weeks for fresh tattoos; 4–6 weeks for old fibrotic tattoos).
3. Apply fractional CO₂ laser: it creates microscopic thermal columns to build micro-channels. These channels release trapped heat, gas and inflammatory fluid, break dense dermal fibrosis to free pigment trapped inside scar tissue, and trigger collagen remodeling to refine skin texture and lower permanent scar risk.
4. After 1–2 months of recovery, repeat the cycle alternately until ink is cleared.

2. Same-session Combined Treatment (Advanced technique, strictly for experienced practitioners)

Deliver picosecond laser first, followed immediately by fractional CO₂. The micro-channels created by CO₂ act as pressure vents to discharge heat and gas generated during pigment fragmentation, significantly reducing blistering and swelling.
