It would be great if we could all have beautiful looking hands. On the narrow side with long fingers & even shaped nails. We would all love to have even complexioned hands with no marks like we see in magazine adds. Utopia for most of us! If we can't change the shape of our hands, we can at least help make then comfortably smooth with, hopefully, strong nails.
This category is so large, with so many options, that it makes it hard to chose. Price is also to consider. You can get sample sizes at the drugstore of about $1 as well as high end ones in the $100 range.
Once in a while on Makeup Alley's Skin Care Board, we get questions like “What is the best of this or that?” This implies most of the time, on the expensive side. Often there will be no answers. The reason being that once you start to get interested in ingredients, their purpose & actions on skin, you figure that they are all similar & some “lower” end products are in fact superior. But again, for some of us, the presentation, or, just the fact of saying we use Dior, La Prairie or Chanel makes us feel good. It's like owning a pair of Gucci sunglasses or a nice Guerlain compact. Most of them are good & so it only depends on how much you're prepared to spend.
