What’s the best Korean skincare routine for oily skin? I’ve already written a post on how to take care of oily skin types and it’s just 3 steps in the morning. Compare that to 10 steps in a Korean skincare routine! But if you’re a fan of skincare products and rituals, this is how I would adapt my skincare routine. I’ll tell you what to use, what you can skip without compromising results, and the best Korean skincare products for an effective oily skin routine. Let’s get started:
Why Your Skin Is Oily (And Why Harsh Routines Make It Worse)
Here’s something nobody tells you when you’re standing in the skincare aisle reaching for the most aggressive cleanser you can find: stripping your skin of oil doesn’t fix oily skin. It makes it worse.Your sebaceous glands produce sebum – a lipid-rich film that protects your barrier, seals in moisture, and generally keeps your face functioning like it’s supposed to. The reason some people’s glands go into overdrive is mostly hormonal. Androgens drive sebum production, which is why oily skin often kicks in during puberty and why it can fluctuate with your cycle.
That part you can’t really control with skincare. What you can control is whether you’re accidentally telling your skin to produce even more excess oil. Because when you over-cleanse, over-exfoliate, or skip moisturiser entirely (all things people with oily skin are routinely told to do) your skin reads that as a threat and compensates by producing even more oil. That rebound effect is real, it’s documented, and it’s the reason so many “oily skin” routines make things worse over time.The goal of a good K-beauty routine for oily skin isn’t to eliminate oil. It’s to regulate it. Those are very different things.
Korean Morning Routine For Oily Skin
Step 1: Cleanser
A single gentle, low-pH water-based cleanser is genuinely all that’s required in the morning, and the COSRX Low pH Good Morning Gel Cleanser is the one that comes up time and time again for good reason. It cleanses without wrecking your skin’s natural pH balance. Massage it in gently, rinse with lukewarm water, done. That’s the first step.
Step 2: Niacinamide Serum
If there’s one ingredient that belongs in almost every oily skin routine, it’s niacinamide. The research is genuinely impressive: a double-blind, placebo-controlled trial found that 2% topical niacinamide significantly reduced excessive oil compared to placebo. It also strengthens your skin barrier, fades dark spots left behind by breakouts, and is so gentle, even sensitive skin can use it. The Beauty of Joseon Glow Serum pairs niacinamide with propolis to soothe irritations. Apply a thin layer and give it a moment to absorb.
Step 3: Lightweight Moisturiser
This is the step most people with oily skin quietly drop, and in all fairness, some people can drop it without their skin being the worst for wear. If you want to use one, look for gel-cream textures with hyaluronic acid, a humectant that draws water into the skin without adding any oiliness or heaviness. The Purito Oat-In Calming Gel Cream does this well; it’s fragrance-free, non-comedogenic, and sits nicely under SPF without pilling or making your face feel like a glazed doughnut.
Step 4: SPF
The final step, every single morning, no exceptions. UV exposure gives you wrinkles, makes dark spots darker, and causes long-term damage that no amount of active ingredients will fully undo. The reason Korean sunscreens get talked about so much is that they’ve genuinely solved the texture problem that makes a lot of people skip this step. They’re developed to feel weightless, absorb fast, and leave no white cast or greasy feel. The Beauty of Joseon Relief Sun is one of the most beloved options – a water-based sunscreen with SPF 50+ that feels like skincare and sits beautifully under makeup. Apply it as your final step, let it set, and you’re done.
Korean Night Routine For Oily Skin
Steps 1 & 2: The Double Cleanse
Let’s get one first straight: you do NOT need to double cleanse. I repeat, you do NOT need to double cleanse. I know the logic makes sense. First, you use an oil-based cleanser to remove oil-based impurities (your SPF, pollution, the day’s accumulated sebum) followed by a water-based cleanser to remove water-based impurities. BUT, a good cleanser will remove all impurities anyway. This is why I always recommend only one cleanser to my clients. As this is a Korean skincare routine though, I’ll tell you what to use to double cleanse, if you so choose. Because double cleansing isn’t bad for skin. It’s just unnecessary (and bad for your wallet).
For oily skin, go for a lightweight cleansing oil rather than a thick balm. Something like the Anua Heartleaf Pore Control Cleansing Oil rinses away without leaving any residue or that dreaded film that makes your face feel like it’s still dirty. Massage it in, emulsify with a splash of water, rinse, then follow with your low-pH gel cleanser. Two minutes, total. That’s the double cleanse. And to be clear: this belongs in your night routine only. Morning double cleansing is overkill.
Step 2: BHA Toner (Every Other Night)
Korean toners are not the astringent, alcohol-drenched things you might remember from the Western skincare world. They’re lightweight liquids that prep the skin and, in the right formula, deliver actives efficiently. For oily and acne-prone skin, a BHA toner a few times a week is one of the most genuinely useful things you can add to your routine. Salicylic acid (a beta hydroxy acid) is oil-soluble, which is what makes it so effective for this skin type. It can actually get into your pores rather than just sitting on the surface, dissolving the mix of dead skin cells and sebum that causes blackheads and congestion.
The clinical evidence is solid: a 2025 trial found that twice-daily salicylic acid use reduced sebum levels by over 23% in three weeks, alongside measurable improvements in acne severity and skin texture. Just Be careful when you pick a product. Most Korean BHA toners use very low percentages or derivatives that don’t do much. If you want to use a Korean BHA toner, here are the best options. But frankly, this is the one product when option for a Western option makes a lot more sense (my fave options here).
Steps 4 & 5: Serum and Moisturiser
Same as the morning. Niacinamide serum, then lightweight gel-cream. Your skin does its repair and renewal work overnight, so keeping it properly hydrated and supported matters just as much in the evening as it does during the day.
What You Can Honestly Skip
If you ask me (and I guess you are), Korean skincare likes to add extra steps just to make you buy extra stuff you don’t need. So, while using the stuff above isn’t going to hurt your skin, it also won’t do much for it. My advice: save your money on these products:
- Essence: Only worth it if it contains something your skin actually needs that you’re not getting from what you’re already using. A plain hydrating essence adds a step and not much else. The vegan kombucha tea essence and fermented ingredient trend has some logic behind it, but it’s a nice-to-have, not a foundation.
- Sheet masks: Great occasionally. Not a routine staple. Once or twice a week if you enjoy them, but they’re not doing anything your serum isn’t already doing.
- Clay masks: Useful for extra oil control when you need it, but again – occasional use, not a daily or even weekly requirement.
- Eye cream: Only if you have a specific concern around the eye area. Oily skin doesn’t make eye cream necessary.
- Ten steps for the sake of ten steps: The coveted glass skin look K-beauty is known for is the result of the right ingredients used consistently over time – not product count. A five-step routine with niacinamide, BHA, a good cleanser, lightweight moisture, and solid SPF will beat a bloated 10-step routine built around filler products every single time.
The Bottom Line
The funny thing about oily skin is that once you stop trying to nuke it into submission, it actually behaves. A solid K-beauty routine isn’t about ten steps or a shelfie-worthy collection of products – it’s about giving your skin what it needs and leaving it alone to do its thing. Niacinamide, a good BHA, SPF for sun protection, and a moisturiser you’ll actually use. That’s genuinely all it takes. Stick with it for six weeks and your skin will do the rest.
