New to DE shaving, Rockwell razor tugging on chin and mustache

Hey all,

I’m new to safety razors and using a Rockwell 6C with the #3 plate. Gillette Foamy has worked okay, but I picked up Cremo and I’m not sure I’m using it right. It doesn’t give much cushion and my shaves feel worse with it.

My main issue is tugging around the chin and mustache. Cheeks and neck are fine. Is this a blade sharpness issue? Currently I’m just using the Rockwell blades.

Should I try a higher plate like #4? Or is my lather the problem?

Appreciate any advice. Thanks!
