I have not been using soap, body soap or any type of facial cleaners for over 4 years. During this time I have been experimenting with different methods of keeping my skin clean and plain water with a luffa worked the best. Using this method, provide gentle exfoliation of death skin and keep pores open.
For the first few days, my skin felt thigh and dry, but after it returned to it soft and smooth state. Occasionally, I do use oils for my body, when I feel need for an extra protection.
Disclaimer: I am using soap on the daily basic to wash my hand and feet if walking bare foot.
