1. First find two pictures with similar faces, such as the pictures of the following two stars, Jackie Chan and Liu Yifei. No offense, please don't take it personally.

2. Then create a new blank layer in Photoshop and put the picture into the blank layer, as shown in the figure.

3. Then open another person's face in ps and cut it out to the right size.

4. Drag the cut picture to the face of the person who needs P, and adjust the size to make the face size consistent.

5. Adjust the transparency of Jackie Chan's face, reduce the transparency, and then make the eyes, nose and mouth of the two faces basically align, as shown in the figure.

6. Then select the eraser tool, set the hardness to 0, and then set the flow rate to about 30%, as shown in the figure.

7. Use the eraser tool to erase all unnecessary things next to your face, leaving only the five senses.

8. Then you can increase the opacity, which will make the picture clearer and less obvious than the overlap.

9. Fine-tune the curve to make the two skins close. Of course, it can't be exactly the same, and further surgery is needed because the skin color is different.

10, then choose the blue channel and adjust it to make the skin color almost the same, which is much better.

1 1, and then erase some unsatisfactory parts with an eraser. The final effect is as shown in the figure, and the feeling is still quite realistic.
