Skin Of Youth Healthy, Younger looing skin

What’s a good skin care routine to achieve smooth, healthy, and flawless skin?

I have couple blackheads here and there, along with some whiteheads. My skin type is a combination of dry, and oily. I'm tired of having acne, it's so frustrating to deal with. My confidence level has dropped down a lot. I need help. So, what's a good skin care routine to achieve smooth, healthy, and flawless skin?

Thanks for answering!
