Preshave Lotions are products intended to be used by men immediately prior to shaving. These products typically contain an astringent which causes bristles to lift up from the skin’s surface, facilitating a close shave. Preshave Lotions are most frequently used with electric shavers but they can also be used when wet shaving. The safety of Preshave Lotions is established by selection of ingredients that are safe and suitable for this purpose. In addition, Preshave Lotions are assessed for their potential to cause skin or eye irritation or cause allergic reactions. Product safety is also established through strict adherence to the principles of Quality Assurance and Good Manufacturing Practices. This includes testing the compatibility of the product with packaging as well as shelf-life stability. Finally, the safety of products is monitored in the market-place to track any reports of consumer injury. Companies include a phone number on their products where comments or complaints may be reported.
