Dezente ästhetische Vorher-Nachher-Porträtvorschau

Create a restrained virtual aesthetic preview from the uploaded portrait of an American adult. Preserve the person’s exact identity, age, ethnicity, facial bone structure, expression, camera angle, hair, pores and natural skin texture. Make only subtle, believable changes requested by the user, such as gently softening under-eye shadows, balancing skin tone or previewing conservative lip-volume changes. Keep lighting and background identical so the comparison is useful. This is a non-medical concept visualization, not a guaranteed clinical result. Do not erase all texture, whiten skin, reshape the face, add glamour makeup, exaggerate procedures, add text or a watermark.
