Have said this a few times, but
You have to understand the root of the problem to address it (pun)
Our facial hair doesnt grow out straight, it naturally coils. Coiling back into the skin is what causes the inflammation
On top of whatever shaving method you use, the BEST thing you can do is to loosen the coils regularly.
Either with a manual toothbrush, an electric toothbrush, or a buf-puf...use something to gently rub against your facial hair. It frees the ones that are coiling into your skin.
In the old days, they marketed buf-pufs directly to Black men for that purpose.
