Fractional C02 laser resurfacing removes the skin tissue layer in a step-by-step method (removes the skin pillars, leaving the skin around each pillar intact to help healing) to help reduce “age spots” (also called sun freckles, liver spots, and freckles) ), fine lines, wrinkles, scars, uneven skin tone, loose skin, irregular texture, dull skin tone, and thinning of the collagen layer on the face, neck, and breasts.
