Beginner at skincare - Advice needed!

Hi there! I recently decided I wanna make a skincare routine for myself but I don't really know where to start. I have oily skin (especially in the nose region) and sebaceous filaments which I wish to remove/minimise. Ive gone through multiple tiktoks and instagram reels for different product recommendations/advice for my age range (Im 18), but it all seems so overwhelming. Would appreciate any tips/advice on products and how to make a routine!
