how often to change m3 blade

I like to shave my face with an mach 3 blade.

I shave about every day. I do have thick facial hair.

Thanks to all who reply

I would probably say about 1 - 2 weeks depending on how thick the hair is. It’s not really an exact science, I always find that when shaving my neck I can tell whether I’m going to need a new blade or not. Just see whether it glides over or feels far more rough and aggressive on your skin, if it does just change it.

Kind regards,

when you’re not getting smooth shave anymore, which is probably every 1.5-2 weeks for you.
