What product is commonly used to protect the skin before shaving?

Pre-shave oil is commonly used to protect the skin before shaving because it creates a barrier that helps to reduce friction between the razor and the skin. This barrier allows the razor to glide more smoothly, minimizing the risk of nicks, cuts, and irritation, which can often occur when shaving. The oil also moisturizes the skin and prepares it for a comfortable shave by softening the hair and providing a slick surface for the razor.

Beard oil, while beneficial for conditioning facial hair and the skin underneath, is not specifically formulated for use as a protective layer during shaving. Aftershave lotion, on the other hand, is applied after shaving to soothe and hydrate the skin but does not provide the protective benefits needed prior to shaving. Hair gel is typically used to style hair and does not offer any protective aspects for the skin while shaving.
