Thumbnail gel định hình chân mày tự nhiên

Create a complete vertical 9:16 promotional thumbnail/poster, not a plain single image. Use [ảnh người mẫu] as the exact female model identity reference and [ảnh sản phẩm] as the exact eyebrow styling gel reference. Feature a large beauty close-up of the model holding the eyebrow gel and carefully brushing one eyebrow upward. Include an enlarged eyebrow close-up showing clean defined hairs, a macro panel of the spoolie brush, a clear packshot of the tube, and a subtle before/after brow comparison. Add a bold Vietnamese headline and short benefit labels such as 'Vào nếp tự nhiên', 'Không bết cứng', 'Giữ form lâu'. Keep the result realistic, elegant and commercially polished. Preserve the exact product design. Vertical 9:16, realistic skin and hair, anatomically correct hands, no fake logos, no watermark, no unrelated cosmetics.
