I don’t know what to do!!

I started my skin care journey almost 2 years ago! I always had good skin barely complain about it. I used the Mario badescu because of tiktok 🤦🏽‍♀️ it kinda irritated me but left my skin glowing and then I started using the cleanser from cerave and later I the ordinary! Tiktok influence my skincare routine a lot and now I’m gonna start using the bs skin care i wanna see how that goes! well my main concern is I’m just try have my skin with no blemishes and dark spots because I’m not worried about acne! Any recommendations I feel the things I used don’t help me at all the ordinary is great it gives me a glowy and healthy look but idk if it’s working I’ve using It for almost 4 months. Cerave I use it to clean my face from dirt and oils. I feel like I don’t know what I’m actually putting in my skin.
