What is the best material to sculpt with that is the most like skin?

Ok so I am making a sculpture that has a posable armature inside of it. I have always just sculpted with clay but I would like to have my sculpture posable once I am done like a very detailed action figure. So i was wondering what is the best material to use that will bend like skin but will not break easily or crack.What is the best material to sculpt with that is the most like skin?
Instead of 100% silicone adhesive from Home Depot, if you plan on doing this much, you need to learn about the various silicone products that produce soft products - usually by molding. Look up RTV Silicone on the internet and contact the maker (GE is one) or distributor near you. They will be happy to bury you under information and data sheets.What is the best material to sculpt with that is the most like skin?
Silicone from home depot - mix some dish soap in water and squeeze the silicone into it - form little patties (like little hamburgers) and apply to your form - after it dries, it will be pliable and bendable just like latex rubber - good luck and sculpt!!!
Silicon rubber a two part synthetic rubber is a castable liquid. But if your seriously into skin effects investigated the work and methods of Duane Hanson hyperrealist sculptor.
