Uses
You can use chili peppers topically and internally, and they taste great too!
Oil infusions work wonderfully for the skin since they tend to be a bit gentler. Make sure not to make the oil to potent though or it may blister the skin.
A good way to test it is to taste it! If you can handle the spice it should be ok on the skin.
