左边涩右边回甘，这张对比图分层挺准
左脸粗糙带斑，右脸细腻均匀，柔光把反差萃得很干净。
✍️ 对比图的门道在光线要一致——左右两半用同一种柔光，反差才可信，不然像PS贴图。手机拍摄这个设定也是关键词，太精致的棚拍质感反而显假。

A before-and-after transformation of age-spot treatment, shown as a close-up comparison of a mid-age woman's face. On the left: deep wrinkles, visible pores, a prominent dark-brown age spot on her cheek, skin textured with sun damage, pigmentation and fine lines. On the right: a significant improvement -- smoother skin, more even tone, reduced wrinkles, no visible age spots. Lighting is soft and clinical throughout, clearly emphasizing the contrast between the two sides. Include her entire face along with hair and shoulder, not a tight close-up, and have her looking toward the right side; the left half of the frame is the before, the right half is the after. Shoot it like a mobile phone photo in an at-home setup -- no blurry background, but the background should stay clean.

呈现祛斑护理的前后对比，聚焦一位中年女性面部的特写对照。左侧：深纹、毛孔清晰可见、脸颊上一块明显的深棕色斑，皮肤带有日晒损伤、色素沉着与细纹的质感。右侧：显著改善——肌肤更光滑、肤色更均匀、皱纹减少、斑点消失。全程用柔和的临床感光线，清楚地衬出两侧的反差。要露出完整的脸部连同头发与肩膀，不是贴脸特写，让她面朝右侧；画面左半是治疗前，右半是治疗后。拍摄手法要像手机随手拍的居家场景——背景不能虚化，但要保持干净。
