So what does aftershave do? Aftershaves are designed to reduce the irritation, razor burn and bumps caused by shaving. They do this by clearing your pores of any bacteria that may have been present, post-shave, on your skin, and by then sealing up those pores to prevent the entry of any additional dirt or bacteria.
Aftershaves can also help hydrate the skin post-shave, and the scented varieties of aftershave can provide you with a wonderfully masculine musk following your morning shave, or just before you head out for the evening.
Aftershaves, then, perform a variety of functions, and there is some variation in terms of what the different types of aftershave do for your skin. The traditional alcohol-based liquid aftershaves of the abrasive, slap-it-over variety which will forever be associated with Home Alone are rather different from the gentler, more recent incarnations of aftershave, i.e. the after-shave balms and lotions.
