The most expensive sex dolls (approximately $1,200 and up) are usually made from silicone (usually above $3,000 at 2016 prices) or thermoplastic elastomer known as TPE (below $3,000). Dolls made of either material can be very lifelike, with faces and bodies modeled on real people in some instances, with realistic skin material (similar to that used for movie special effects), and with realistic (or even real) hair. These dolls usually have an articulated PVC or metal skeleton with flexible joints that allows them to be positioned in a variety of positions for display and for sexual acts. Silicone or TPE dolls are much heavier than vinyl or latex inflatable ones (which consist mostly of air), but are roughly half the weight of a real human being of comparable size.
With a TPE sex doll, there are a few cons that do come with this, so it is best to know these. One of the biggest problems is that it often can become sticky and tacky over time. This type of skin absorbs the oils from our hands and skin a whole lot more, which is why over time they do get sticky. However, you can use a renewal powder on this in order to help clean it up. But it is something that you should certainly keep in mind.
Now, TPE stands for thermoplastic elastomer, which is essentially a mixture of polyvinyl chloride and silicone. This is a type of skin that is very soft, and it mimics the feeling of human skin. TPE is way more realistic in feeling and it definitely mimics the feeling of human skin. It also is much cheaper than silicone alternatives, sometimes even hundreds of dollars cheaper. TPE also allows you to move the doll around in various ways, since it has more flexibility. TPE dolls don’t really need to be bathed, but you can, just be mindful of the water. It also is hypoallergenic as well.
