Both serums for the anal area work without any anaesthetics. They have been developed to reduce sensitivity during this particularly fun activity without limiting the pleasure you experience. What makes these products special is that they take effect after just 15 – 20 seconds and not 15 – 20 minutes like many competitor products. The serums are not absorbed by the skin. Instead, they form a protective film, which means they are particularly skin compatible and help protect the skin.
