Oily skin problem

Hello!

I need some advice about my skincare routine... I always had a very oily skin and it's not been long since I've started a real skincare routine in the morning and the evening. Those are the products I use ;

- Beauty of Joseon's Green Plum Refreshing Cleanser

- Beauty of Joseon's Glow Serum

- Centella's Pomerizing Light Gel Cream

- Beauty of Joseon's Matte Sun Stik (only in the morning, if I go out)

After trying a lot of things, I've found those and I've been told that they are good products for oily skin... But, you guessed it... No matter what I do, my skin stays oily and it glistens and I HATE it. 😭

I'm tired of just buying and buying and buying products and for them to never work. It's better if I only use the cleanser but, apparently, it's not good for the skin... So I'm a bit at a loss, here... If anyone with the same problem has a solution, I'm all ears... 🥲

Thanks in advance!!
