Reddit reviews Chavant Clay - NSP Medium Brown - Sculpting and Modeling Clay (1/4 Case)

Hahaha, yes. Sculpt Gel is a product from Mouldlife, in the UK. Here's an info sheet on in it.

In North America there's a product called Skin Tite

and Third Degree

and Brick in the Yard has a Gel-10 cut kit

Brick in the yard also have an amazing youtube channel, if you've not checked it out yet :)

If you're in a colder climate (because in hotter climates it will melt off your face), you could also use gelatine, which is awesome and more affordable. Here's a video on how to make your own movie grade gelatine at home.

This is the plasteline I use using.

These are the teeth, but it looks like they're unavailable right now. There's similar ones on other sites.

I will try to make a video on how I did it over the next week, and upload it to my youtube channel (which has just passed half a million views, HOLY SHIT.)

edit: adding more info. Brick in the Yard also have a bunch of videos on how to do a face cast, if you want a plaster mould of your face (I used alginate for mine). And there's a bunch of brush-on casting silicones which you can use to make a mould of the plasteline, I just purchased some pinkysil, and the resin I used was the trowel-on, but there's heaps of different things you can use.

Oh we used this type of clay

And our sculptures are not the pottery type but more playdough type. The clay gets tough overtime but melt under the heat.
