Before-After Ad — Brightening Serum

A 1080x1080 px before-and-after skincare advertisement for a fictional brightening serum called LumaPeel Glow Serum by fictional brand ClearSkin Lab. The image is split vertically down the center with a thin white dividing line. Left panel labeled "Week 1" in small white sans text at the top: a close-up photograph shot with a 100mm macro equivalent, ring-flash lighting revealing texture of a skin patch on a forearm area showing uneven tone and subtle dry patches — realistic, clinical, not exaggerated. Right panel labeled "Week 8": the same skin area noticeably brighter, more even-toned, with a healthy dewy sheen, under the same ring-flash conditions. No real faces — the crop is tight enough to be anonymous. Below the split: on a pure white background, the product shot of the serum bottle (30ml amber glass dropper bottle with a gold dropper top and a minimalist label reading "LumaPeel Glow Serum") centered. Headline: "Clinically Tested. Visibly Different." CTA: "Shop Now" pill in amber.
