How to shave without damaging your skin
Shaving is the most typical start to a man's skincare regime, and it is the first area where they can make mistakes. Most shaving gels or creams, pre- and post-shave products, especially those geared toward men, contain irritating ingredients such as alcohol, menthol, mint, and camphor, as well as high levels of potassium or sodium hydroxide. These ingredients are skin irritants that make the hair follicle and skin swell, forcing the hair up and away from the skin, supposedly allowing for a closer shave.
Unfortunately, the irritation and resulting swelling cause some of the hair to be hidden by the swollen follicle and skin. Note that sodium hydroxide is used in many skincare products at very low levels (the lesser amount of an ingredient in a product, the lower it will be on the ingredient list on the label) to adjust the pH value. In these low quantities, it is not irritating to skin. Additionally, the swollen skin makes it harder for the stubble to find its way back out. If the hair begins to grow (which it does almost immediately) before the swelling is reduced, the likelihood of ingrown hairs is increased.
Shaving with a razor abrades the skin enough to cause havoc, but then men typically splash an alcohol-based post-shave lotion with irritating ingredients over that broken skin. Try splashing some post-shave lotion on a cut or scrape on any other part of your body. Now, why would you want to do that to your face and damaging your skin?
