Rough on the Left, Smooth on the Right, Cleanly Split

A before-and-after transformation of age-spot treatment, shown as a close-up comparison of a mid-age woman's face. On the left: deep wrinkles, visible pores, a prominent dark-brown age spot on her cheek, skin textured with sun damage, pigmentation and fine lines. On the right: a significant improvement -- smoother skin, more even tone, reduced wrinkles, no visible age spots. Lighting is soft and clinical throughout, clearly emphasizing the contrast between the two sides. Include her entire face along with hair and shoulder, not a tight close-up, and have her looking toward the right side; the left half of the frame is the before, the right half is the after. Shoot it like a mobile phone photo in an at-home setup -- no blurry background, but the background should stay clean.
