Non-glycerin lubricant is a type of lubricant that does not contain glycerin. Glycerin is a common lubricant ingredient, but some people may have allergic reactions or discomfort to it, so they need to look for glycerin-free lubricants. Non-glycerin lubricants typically use other natural or synthetic ingredients to provide lubrication, and their texture and lubricating effect may vary depending on the ingredients, but they generally provide comparable lubricating effects to glycerin-based lubricants. Non-glycerin lubricants are suitable for various situations, such as sexual activity, masturbation, and use with toys. It is recommended to test the lubricant on a non-sensitive area of the skin, such as the arm, before use to ensure that there is no discomfort or allergic reaction.
