That may seem like an odd question, but it is one that deserves some consideration. Do you use a soap simply because it smells good? Or is it that you like its anti-bacterial properties? Many soaps today smell nice but are not necessarily the best to use on your skin in order to get a proper clean. What I have found over the years is that soaps vary in many different ways. Dove, for example, leaves a slimy, slippery feeling on your skin and is, in my opinion, hard to wash off. Castile, Protex, Refresh, and Dial are easy to wash off and come in various scents. Most of the scent variations are nice, but a few are not as appealing as the rest.
The brand of soap that you use is up to you. But keep in mind that you should seek out those that are effective in removing dirt from your skin. The last 4 ones that I mentioned are the ones I like best. They easy to wash off, anti-bacterial, and they smell good.
