Excellent video on how to prepare your skin for shaving with a razor if you have sensitive skin. Also do not forget to add some type of moisturizer to replenish the oils in your skin.
Here are 3 things that I learned from this video.
#1 : The shaving brush is also used to lift the facial hairs, and exfoliates in preparation for a close shave, not just to apply the cream.
#2 : Your facial hair is not dulling the razor, allowing water to dry on it is. Remember to dry the razor after each use by patting it with a towel so as to prevent water buildup and dulling of the blade, or blades.
#3 : Use a moisturizer after you shave instead of aftershave. The reason for this is, during shaving you remove a layer of skin on your face and you loose moisture in your face causing irritation if you do not replenish with a good moisturizer right after you shave. Many aftershaves do not have the necessary moisturizers in them, so you may experience more irritation with them as opposed to using a moisturizer.
Good luck. Hope this helps.
