Shaving exfoliates the skin, making it supple and ready for bronzing, thus it should be done before applying self-tanner, but not just before, because shaving can open pores and cause cuts. Shaving after applying self-tanner will not remove the product, but it will soften the hair so that it can be washed away. The best way to avoid razor burn while shaving is to use a quality razor with good blades. You should also shave with the grain, not against it. The skin will feel better and you won't get cut. Don't forget to clean your razor regularly, too; all those products are good for your skin! If you aren't comfortable with shaving, consider using a beard balm instead. These products coat the hair to protect it from the razor and help create a smooth finish. Some contain ingredients such as coconut oil or shea butter which are great for skin too! Hair grows in areas where it's protected by a beard or mustache. If you don't want to grow anything yet still want to enjoy the benefits of self-tanner, use a fake beard. There are products available that will make your face look like it has a beard even though it doesn't have any hairs on it.
