Soap. My mom and sisters always complement my hair and skin, asking what products I use. I just use 2$ Yardley bar soap for skin and hair. I also like them because they smell nicer than other cheap brands that just have a generic detergent smell.

Skin is waaay too individual to make recommendations. Some people can use dove bar soap on their face and never have acne or other skin problems. Others are acne prone and have to do multiple things in order to keep it under control.
