The Heros silicone-based lubricant 200ml is based on silicone. Although silicone-based lubricants are somewhat more expensive, they offer some significant advantages. HEROS has extra long-lasting lubricity, as silicone molecules remain on the skin for longer. This means you don't have to keep reapplying. HEROS is also particularly skin-friendly, oil-free and compatible with latex condoms. Thanks to its excellent lubricity, you can also use HEROS for massage. Compared to other silicone-based lubricants, HEROS is super concentrated.
