How to prevent bumps after shaving

Hi guys! I really need help :( (sorry if this is the wrong place!)

EVERYTIMEEE I shave my arms or legs, I get really weird painless bumps on them. They are kinda like keratosis pilaris but as far as I know, those arent caused by shaving.

Is there anything I can do to prevent these? All I do is moisturize before and after, and exfoliate. I use a Gilletes Mens razor as well.

Any tips would be appreciated, thank you 🩷
