Create an ultra-realistic vertical 9:16 skincare advertising photo. Show [Subject] gently applying [Product] to both cheeks with both hands, eyes closed and a soft smile, with smooth luminous skin, hair tied back, and a [Towel Color] towel wrapped around the hair and body. Place the scene in a luxurious modern bathroom with green aesthetic tiles, indoor plants, and morning natural light streaming through a window. Build a clean spa atmosphere with high-end cosmetic commercial photography, fine skin texture, dewy glow, and a centered product tube on a marble countertop in the foreground. Use a minimal elegant composition, soft shadows, pale green and white color palette, shallow depth of field, DSLR-quality sharpness, natural makeup, and a calm wellness mood. Do not imitate or name a real celebrity or private person unless the user has authorization; avoid real brand logos, readable product labels, private information, extra watermarks, distorted anatomy, awkward hands, and low-resolution artifacts. Output aspect ratio: 9:16.
