What is a preventative measure for skin irritations during shaving?

Using a pre-shave oil is an effective preventative measure for skin irritations during shaving because it creates a protective barrier between the skin and the razor. The oil helps to soften the hair and lubricate the skin, reducing friction during the shaving process. This lubrication minimizes the risk of nicks, cuts, and irritation, allowing for a smoother glide of the razor across the skin. Additionally, pre-shave oil can help to hydrate the skin, making it more pliable and less likely to become irritated from the shaving action.

In contrast, shaving against the direction of hair growth can often lead to increased irritation, as it may cause unnecessary pulling on the hair follicles and skin. Using a dull razor exacerbates the risk of irritation because it requires more pressure to cut the hair, which can lead to more friction and potential skin damage. Lastly, avoiding moisturizing products would not be beneficial; on the contrary, properly hydrating the skin helps to keep it healthy and reduces potential irritation during shaving.
