How to remove blemishes from skin without smoothing the whole face
Ask Vizard Agent to map the blemishes and their movement before it corrects anything, then apply a feathered fix to only those areas. A correction applied to the whole face cannot tell a spot from a pore, so it removes both, which is why retouched video so often looks like a mask rather than a person.
What do you type into Vizard Agent?
Name what stays as well as what goes. Without that second half, the instruction reads to Vizard Agent as "improve the skin", and improving skin is precisely the operation that flattens it into something that looks moulded rather than photographed. Say how far to go, too: calmer often reads better than gone entirely.
Prompt
What does Vizard Agent actually do?
Smoothing works by removing texture, and a blemish is texture like any other. Blemishes sit in particular places on a particular face, and that face moves, so the correction has to follow them rather than being applied to a region of the frame. In the session behind this article it:
- Sampled representative frames, checked the available retouching approaches and applied a whole-clip blemish removal as a first attempt, which was then rejected.
- Extracted detailed frames to map the blemish areas and their movement, zooming into the main cluster across time to track it consistently.
- Built a localised, feathered retouch for only the mapped areas and tested it on a one-second sample before committing.
- Rendered a bounded preview to confirm the surrounding skin was untouched.
- Refined the masks, strengthened only the local smoothing and tested an interpolation pass for the last stubborn marks.
When does this not work well?
Some corrections can't be made locally. Widespread redness, a texture change across a whole cheek, or marks moving under heavy motion blur won't respond to a feathered patch, and Vizard Agent will suggest a gentler overall grade instead. Very low resolution leaves no texture to protect, strong side lighting shows the correction at the shadow edge, and long clips give the tracking more room to drift.
Common questions
Why not just smooth the skin? Because smoothing cannot tell a spot from a pore. Vizard Agent maps the spots instead.
Will freckles survive? Yes, if you say so. Tell Vizard Agent what counts as a blemish and what does not.
Can I see it before the render? Yes. Vizard Agent tests on a one-second sample, which is much cheaper than a full pass.
