Silicone lubricant is a long-lasting personal lubricant designed to alleviate friction during vaginal or anal sex. Silicone lubes have a super smooth, silky feel, and they're usually hypoallergenic. Since the silicone molecules are too large to absorb into skin, silicone lube stays slick and slippery and lasts longer than most other lubricant types, so you don't need to re-apply as often, if at all. Silicone lubricant is also able to stay slippery underwater, making it perfect for sex in the bath or shower.
Silicone-based lubricants aren’t suitable to be used with silicone sex toys as silicone reacts with silicone, which will break down the sex toy material. Silicone lubricant can also stain sheets and is harder to wash off and remove than water-based lubricant.
