Basic products good for complex conditions

I'm not exactly sure what my skin type is~

But I feel like I am both oily and dry.

I always say I have combination skin.

When I was young, I often had acne on the T-zone area.

The cursor feels tight on my face, and the skin feels tight underneath, so I have always been worried.

Is there a basic product that is good for someone like me?

Could you possibly recommend something?
