PS repair method, how to repair human skin?

This question is rather broad, so it is hard to be specific. Let's briefly talk about the process:

The first thing to do before retouching is to open the color space, correct the skin color and contrast, and make the exposure and skin color accurate. It's usually done by curves (the picture is ever-changing, so it's hard to be specific)

Simple modification to remove obvious acne and broken hair. Use a repair tool.

Grind the skin properly with the dermabrasion filter (be sure to keep the details), and then grind the skin carefully with the imitation stamp. The dermabrasion filter can be omitted when there is time. What other hyperbola, neutral gray, high and low frequency skinning methods should not be sought after by novices. Those methods should have a certain artistic foundation. As for light and shadow, those methods are best operated by graphic tablet, and the mouse can kill people. As long as the imitation printing is used well, it is not a problem to use the wedding photos of the wedding studio.

It is necessary to consider color mixing here. This problem involves a wider range, different films, different scenes and different ways, and it is difficult to explain it in detail. This requires a lot of practice and aesthetics to judge the suitable skin color and environmental color of the film.

Optimize the relationship between light and shadow of the film and increase the three-dimensional sense. Simple lightening and deepening tools can be used, and high-standard neutral ash can be used.

The last step is sharpening. No matter how good the film is, the sharpness is more or less insufficient. People always like clearer photos. Simple sharpening methods can be sharpened by USM, and advanced ones can be sharpened by intelligent sharpening or Gao Fancha sharpening, and the brightness channel can be kept in sharpening laboratory mode.

The above content is written by myself, maybe you are not the answer in your mind, but there are many skills in PS that can't be described in words because there are too many variables! Different photos have different processing methods! It is difficult to cover all situations!
