Oily skin still needs hydration — stripping it harshly can backfire and leave skin tight and reactive. The aim is to cleanse gently, hydrate with lightweight textures, and manage shine without over-drying. A few researched ingredients come up a lot: BHA (salicylic acid) is oil-soluble so it works inside pores, and niacinamide is studied for barrier support and a more even tone. Below are the Korean product types oily skin tends to reach for, with honest notes. Patch test, and see a dermatologist for persistent breakouts.
