You can see artefact/bump on the cheek and neck on the second picture.
I tested render with GPU and CPU, result is the same.
Also this dark spot do not appears without SSS but appears immediately even if SSS is very small (0.001)
Shadow terminator fix do not influence to it.

Cycles-X with separate SSS with same settings:

Hi @Vyach , Cycles-X branch is under heavy development at present and reports for this branch we are currently not accepting as Sergey Sharybin said: #88628#1167148
Closing the report. Feel free to reopen if problem appears on master branch :)
@PratikPB2123
Okay, it is more like tests and noticing the difference for developers.
As Thomas Dinges said to me «a report cannot harm » :)
So idk if developers know this issue and have enough objects to test it.

@Vyach please use https://devtalk.blender.org/t/cycles-x-feedback/18598 to repost if not there.

I encouraged @Vyach to report it, wasn't sure what the current policy is for cycles-x bugs. @Sergey
@dupoxy done
Changed status from 'Needs Triage' to: 'Archived'
Thanks for bringing it to our attention, we will check on it.
As for official policy, we are not open for receiving Cycles X issues in the bug tracker. Best ways to provide feedback is either the devtalk (linked above) or talk to us in the render-cycles-module room on blender.chat.
@Sergey Okay, will do!
I started from chat :)
But compiled report looks much better as post at devtalk or here
