2. Fractional CO2 Laser

How it works: Using a “fractional” emission pattern, a high-energy CO2 laser beam is divided into countless tiny beams. Each microbeam instantly vaporizes a small area of tissue, creating a tiny pore (Microscopic Treatment Zone, MTZ). The tissue between the pores remains intact. This ensures effective treatment and significantly accelerates healing. The thermal effect causes collagen contraction and regeneration in the tissue surrounding these micropores.

Effects: It has a dual effect. First, vaporization remodeling: it vaporizes old, unhealthy mucosal epithelial cells, promoting the growth of new, healthy epithelial cells, improving color and radiance. Second, thermal stimulation tightening: the thermal effect penetrates deeply into the submucosal layer, triggering significant collagen regeneration and contraction, achieving a superior tightening effect. It is ideal for those experiencing sagging, dryness, and dull skin.

3. HIFU (High-Intensity Focused Ultrasound)

Principle: HIFU utilizes the penetrating and focusable properties of ultrasound. Low-energy ultrasound waves penetrate superficial tissues and focus into a high-energy spot at a specific depth beneath the skin (such as the fascia or muscle layer of the vaginal wall) (similar to focusing sunlight with a magnifying glass), instantly generating a high temperature of 65-70°C. This high temperature causes the collagen fibers in that area to shrink and denature, initiating a collagen regeneration process that lasts for months.

Effects: HIFU acts like an “internal suspension.” Rather than acting on the mucosal surface, it directly targets the fascia and muscles that support the vaginal structure. Therefore, it is more direct and effective in lifting and restoring support for moderate to severe vaginal laxity and prolapse caused by childbirth or aging.
