Oily skin and moisturizer

Its been a while since I hadn’t had a proper skincare routine and stayed consistent, and I really want to try being a better version of myself.

I’ve always had this skin type (oily, clogged pores, sebaceous filaments). I did try skincare once before but I couldn’t stay consistent, so I stopped. But in the meantime I started drinking more water (around 1.5L a day), because before I barely drank any, and I did notice a small difference ; my skin felt nicer and a bit less oily.

But I still have clogged pores, sebaceous filaments, and oily skin, so that’s why I wanted to start skincare again. I've always been insecure about my skin and I'm currently 20.

This time I tried to keep it minimal because before I had too many products. So I only got the basics: a cleansing oil (Centella), a cleansing foam (Anua), a BHA blackhead liquid (COSRX), Dr Althea 345 moisturizer, and sunscreen (Round Lab 1025 Dokdo).

I’ve only been using them for a week, morning and night, but the moisturizer… I don’t really like it. I feel like it’s not lightweight enough for me unfortunately.

I don’t know if I should keep using it and maybe my skin just needs time to adapt, or if I should stop using the 345 cream. And if I stop it, can I just use sunscreen as a moisturizer in the morning? Apparently it is hydrating too, i dont know if it can replace a moisturizer tho.....
