Is it bad to wash your face with a cleanser, toner and moisturizer every morning and night?

I use Pure Calmille Gel cleanser, Sebo Specific 2in1 Toner and Sebo Specific Zero Blemish Pore Refining Care cream every morning and every night (before I go to bed). Sometimes I use tea tree oil on my blemishes so they go away faster. What I'm wondering is, is it bad to use all of those products morning and night? The reason for me asking is that my mother seems to think that sometimes I should not be slapping on products all the time and let my skin just be natural and just use water and a moisturizing cream. She thinks i'm ruining my skin.
