There's a reason why there are facial cleansers. These products are made for different skin types to address skin concerns that you may have. It can range from being oily, dry, normal to combination, etc. Its best to consult a beauty consultant on what facial cleanser would be best for you.
Please no bar soaps. Why? Because bar soaps leave residue on the skin which can lead to breakouts, clogged pores, and so forth.
My personal favorite cleanser is Estee Lauder's Perfectly Clean. Its made for normal/combination skin which I have and it leaves my skin feeling soft and just CLEAN!
