Shaving your face with a razor is perfectly safe, as long as you take a few precautions. First, make sure the razor is sharp and clean. A dull razor can cause irritation, and a dirty razor can spread bacteria. Second, shave in the direction your hair grows to avoid nicks and cuts. Finally, use a good shaving cream or gel to help the razor glide over your skin.
If you follow these tips, shaving your face with a razor is a perfectly safe way to remove unwanted hair.
