Transform the uploaded portrait into a natural, photorealistic youthful adult version of the same person, appearing around 20 to 30 years old. Preserve the person's core identity, facial structure, recognizable features, expression, gaze direction, pose, body proportions, clothing style, background, lighting, camera angle, and overall photo composition. The result should look like a real high-quality photograph of the same person at a younger adult age, not a different person. Make the face look naturally youthful and healthy: smoother but realistic skin texture, reduced wrinkles, fine lines, forehead lines, crow's feet, under-eye bags, dark circles, age spots, sagging, dullness, and tired facial signs. Restore firmer facial contours, slightly fuller cheeks, a cleaner jawline, brighter eyes, fresher complexion, and natural facial vitality. Keep pores, subtle skin texture, moles, freckles, dimples, and unique facial marks if they are part of the person's identity. Adjust the hair to match a youthful adult appearance: reduce or remove gray hair naturally, restore healthy hair volume, density, shine, and softness, while keeping the original hairstyle direction and overall hair shape. If the original hair color is visible, keep a natural younger version of that color; if the hair is gray or faded, convert it into a realistic natural hair color that matches the person, such as dark brown, black, chestnut, blonde, or auburn depending on the original appearance. Avoid unnatural dyed colors unless clearly present in the input image. Improve the overall photo quality subtly: enhance facial clarity, natural skin tone, balanced contrast, clean details, and realistic lighting. Maintain the original realism and avoid beauty-filter exaggeration. The final image should feel like a professional portrait retouch showing the same person in their 20s, with believable adult facial maturity. Do not make the person look like a teenager or child. Do not change gender presentation, identity, ethnicity, facial proportions, hairstyle drastically, outfit, background, or pose. Do not create a plastic, overly smooth, AI-generated, doll-like, cartoonish, fantasy, glamorized, or heavily retouched look.
