[Routine Help] Acne-prone/oily skin, large pores, acne scars + lightweight SPF recommendations? (Interested in Centella/K-beauty)

Hi everyone! I’ve been trying to build a proper skincare routine and thought this would be a good place to ask for honest recommendations from people who actually use these products. I’ve recently been hearing a lot about Korean skincare, especially Centella products, and I’d love some advice on where to start.

Skin concerns:

• Acne-prone skin (had acne since I was around 13, currently 22)
• Combination to oily skin (used Accutane about 5 years ago, so it’s less oily than before, but still definitely leans oily)
• Large pores / blackheads -Mild acne scarring and post-acne marks -Dullness/lack of glow

so I’m guessing I mainly need help with: serum recommendations, moisturiser recommendations, lightweight SPF recommendations (very important because I hate heavy/suffocating sunscreens), products that help with a natural glow without making me greasy...

I also realised I don’t fully understand ingredients yet. For example, I think ingredients like BHA/salicylic acid or niacinamide help with pores and blackheads, but I’ve mostly just followed dermatologist recommendations in the past without really understanding what each product actually did.

So if anyone could also explain: which ingredients are best for pores/blackheads, acne scars/post-acne marks, and oily skin, I’d really appreciate it.

If you’ve personally used Centella products (or any other products you genuinely loved for similar skin concerns), I’d love to hear your experiences.

Thanks so much 💛
