Joven mirando su reflejo envejecido en el espejo

A highly realistic photo of a young woman standing in front of a mirror, looking at her reflection with a subtle sad and introspective expression. She is around 20 years old, natural skin with visible pores, slight imperfections, soft under-eye shadows. The environment is a real bedroom or bathroom, softly lit by natural window light. In the mirror reflection, she appears as an elderly version of herself: detailed wrinkles, sagging skin, age spots, fine lines, realistic aging features, tired eyes, slightly pale tone. The reflection must be perfectly aligned with her pose. Shot like a professional photograph, 85mm lens, shallow depth of field (f/1.8), cinematic composition, soft shadows, global illumination, physically accurate lighting, HDR, ultra-detailed textures, photorealistic, 8K resolution. No fantasy elements, no distortion, no surrealism — extremely grounded in reality.
