Why Smood?

Since these gel contain no water, they never dry up, so they'll stay slick for a long time.

Silicone is great for people with sensitive skin.

They can also be used for full body massages, and they'll leave your skin soft.

Since they won't break down in water, they can be used in the shower or bath (or even underwater or in the rain, if you're into that).

Advice: Not all silicone lubricants are created equal. If you're interested in trying one out, buy the the higher quality ones
