First check if your skin accepts the soap.
Lather your face and dont shave.
Keep the lather for 30 minutes rebrushing your face a couple of times.
If you have no adverse reaction then your soap is OK for your face.

You say your razor stick to your face, maybe that soap is not very slippery.
Take a butter knife, pretent to shave with it, see if it glides easy or sticks.
