Remove blemishes, acne, pimples, freckles, dark spots, acne marks, redness, and other visible skin imperfections with selective retouching, while preserving natural skin texture, pores, fine details, skin tone variation, facial structure, expression, lighting, and identity. Maintain consistent, realistic, age-appropriate skin detail across the face. Output clean, naturally refined skin only. Do not alter facial features, makeup, hairstyle, clothing, background, or composition. Avoid over-smoothing, waxy skin, blur, distortion, artifacts, or unnatural beauty-filter effects.
