[Routine Help] Do you need two different products if you have combination skin and two more products on top of that for when it is colder or hotter?

Do you need 2 different products if you have combination skin and 2 more products on top of that incase of the weather ? I have combination skin where my cheeks are somewhat dry and my tea zone is oily. So does that mean when I use a cleanser that I would need to use a different one on my cheeks then I would in my oily T zone? On top of this does this also mean that I need to use a different moisturizer in those two different area areas as well? Then on top of that because I live in a state that can be really cold in the winter and then really hot in the summer. Do I want two different sets of skin care products for when it’s colder and warmer? I went to my dermatologist today, and I asked him about this, and he said that I at least need a cleanser, a retinoid, a moisturizer, and sunscreen. But after doing some research on the Internet, it seems that you have to change some of these if not all of these products depending on if you’re using it in oily T zone or your dryer cheek zone and on top of that if you are cold or hot weather.
