What are some good skin care products for me?

I’m 13 years old , and I have Normal/Combo skin .

I want to maintain a good clean face so I don’t have to repair it when I’m older .

Me & my mom are going to Rite Aid, Target, and Walgreens tomorrow so I might have a chance to buy some of them .

I need a good cleanser , exfoliater, moisturizer .

Keep in mind a kid like me doesn’t have much money, thanks .
