Steaming your face can make your skin softer for a period time afterwards. It can also make it easier to remove blackheads using your fingers or some sort of strips. I would regulatory steam when I was suffering from acne and my blackheads would be just about ready to fall out after a 20 minute steam session. You can use nose strips with a greater success rate after steaming as well.
You can buy a specialized face steamer and put a towel around you and the machine or for those who don’t have the money you can boil some hot water in a mug and position your face over the mug to catch the steam and then put a towel over you and the mug. Either way works it all depends on your preference and your budget.
Here is a facial steamer I have used in the past with great success.
