Is it bad to use hand soap for my face?

Okay, well first off my face is just really oily and acne prone. I have been using hand soap and warm water and lathering it into my face about once everyday. It has gotten rid of my acne and really evened out my face from the oil. My face doesn't feel too dry, it just feels under control. But my mom insists that hand soap will ruin my face and make my face wrinkle. But it got rid of my acne really well. Is this really that bad for my face?
