Makeup and skincare tips?!? Anything really!

I’m 17 and have recently been getting into makeup and skincare more than usual. Today I bought a Clinique acne solutions foundation and I also bought a personalized acne moisturizer on presell to save my spot for the free 7 piece gift going on. I’ve also recently signed up for boxycharm and got my first box this month! Only issue is I pretty much have no idea what I’m doing. When I do my makeup now I do more of a full face with the foundation, blush, and bronzer where I used to use foundation for spot cover ups and just powder. I have no idea if I’m even bronzing correctly and whatnot and feel like I can’t completely blend my eyeshadow. I want to start getting into a more advanced level of makeup if anyone gets what I mean, so I’m looking for some good tips and makeup recommendations to start out with. Also I have pretty stubborn acne. It’s not horrible but I feel like I’ve tried so many drug store products and nothing has seemed to work to keep it off. Any skincare tips would also help. I have huge pores all over my face as well as blackheads and stubborn acne. I’m willing to spend the money on a good and decently sized and priced product, but I also want to make sure it’s worth the extra money. Any help and tips on anything makeup and skin related would be amazing and so helpful😁
