What is a good age to start using products on your face?

I am turning 13 in May. I have a problem with acne, an oily t-zone, and very dry, flaky and stuff skin on some parts of my face. My nose also has very clogged pores. My mom says I'm too young to be doing this stuff to my face. But I've noticed a huge difference in my skin. It's been softer, smoother, acne has been less noticeable, my face is one color, ect. This is what I use;
I use the exfoliator 4-5 times a week, sometimes I don't have time in the morning. On an average morning I do the scrub, pat dry, wait until my face is compeltely dry, toner (I just recently started using toner), wait for that to dry, and then mousturizer. I use 2 layers on my super dry stiff parts. At night it's the same but the cream cleanser instead. I've recently gotten target brand oil absorbing sheets and I absolutely love them. Is it bad to do this so young? My mom was the one who told me to cleanse my face in the first place because a ton of people were pointing out my acne and my face was not in good shape. Then she gets mad at me for toner, saying I'm too young. Am I? Is it bad? Why? Thank you!
