Aesthetic cosmetology vertical 9:16 split-screen 'BEFORE / AFTER' presentation slide collage based on the reference image. The skin tone and lighting on both sides (left 'ДО' and right 'ПОСЛЕ') must be completely identical, uniform, and balanced: a natural light porcelain/fair complexion with smooth, consistent color temperature across both halves. Keep the precise split-screen layout with the thin golden center line, the elegant gold serif captions 'ДО' (top-left) and 'ПОСЛЕ' (top-right), and the clean white top. The only difference between the two sides should be the lips: natural/untreated on the left, and plumped, glossy, perfected on the right. Photorealistic high-end beauty portrait.
