PicoSure "flat lens" vs "focus lens"?

The PicoSure "focus" lens delivers a more concentrated laser beam than the "flat" lens. This makes the “focus” lens better for addressing wrinkles, acne scars, and uneven skin texture. In contrast, the flat lens is designed for more surface-level pigmentation concerns like sunspots and freckles, offering shallower penetration. The lenses in combination would yield a more intensive and targeted approach, targeting deeper skin concerns.
