Best tip to avoid pimples after shaving your face

Hi (fπŸ’πŸ»β€β™€οΈ),

My boyfriend bought a Henson razor (one blade razor) few months ago and he always gets little pimples or little wounds after shaving. He has a sensitive skin as well. What are your tips to get a nice shave everytime ?

I like when is face is shaved because it’s softer, but he always need to wait to let is face heal before shaving again.

Thanks guys 😊
