Aloe is good for all sorts of things - dry skin, burns, helping cuts/spots/blisters heal, and so on. I have a couple of aloe houseplants and just use these - cut a bit off and rub the gel from inside the leaf straight on the skin. I haven't tried any aloe 'products' apart from the plant itself, which i figure must be the best (and cheapest) source.
I use both 98% Aloe gel and the Proraso pre/post aloe cream. I use both products pretty much the same way, as a pre-shave and as a post-shave moisturizer and healer. My skin really like aloe based products.
