Aftershave describes a lotions, gel, balm, powder, or liquid used mainly by men after they have finished the act of shaving. It may contain an antiseptic agent such as denatured alcohol or stearate citrate to prevent infection of cuts. Menthol is used in some varieties as well to numb damaged skin, and it is an ingredient that shaving cream manufacturers have started including in their formulations, too. It is said that the alcohol (usually SD Alcohol 40-B) in the aftershaves of many mass-market companies closes pores in the skin and therefore prevents further irritation by dirt or bacteria, but there is also contention that this ingredient also dries skin out and disrupts cellular renewal ("razor burn"). Aftershave with alcohol also usually causes an immediate burning sensation in men who apply it post-shave, with effects sometimes lasting several minutes.
