Korean Skincare for Oily Skin: The Summer Routine for Australian Weather

Quick answer: The best Korean skincare routine for oily skin is short and water-based: a low pH gel cleanser, a BHA exfoliant two to three times a week, a niacinamide or centella serum, a lightweight gel moisturiser, and SPF 50+ every morning. Oily skin still needs hydration. Skip moisture and your skin often produces more oil, not less.

If your face is shiny by lunchtime and your foundation slides off by 3pm, you're not alone. Australian summer is hard on oily skin: heat, humidity and sweat all add to the shine. The good news is that K-beauty was practically built for this skin type. Korean formulas lean on lightweight textures, gentle cleansing and hydration without heaviness, which is exactly what oily skin needs.

Here's the routine that holds up from December to March.

Why does oily skin get worse in summer?

Warmer temperatures make sebum flow more freely, so the oil your skin already produces spreads across the surface faster. Add humidity and sweat, and shine builds up quicker through the day.

The common reaction is to strip everything back: harsh foaming washes, alcohol toners, no moisturiser. That usually backfires. When skin is stripped, it can feel tight and dehydrated, and many people find it looks oilier within hours. The goal isn't to remove all oil. It's to keep skin clean, hydrated and balanced so the shine stays under control.

What is the best Korean morning routine for oily skin?

Keep mornings to four or five steps. Your skin hasn't collected makeup or SPF overnight, so one gentle cleanse is enough.

1. Gel cleanser. A low pH gel cleans away overnight oil without leaving skin tight. Try the COSRX Low pH Good Morning Gel Cleanser or the Round Lab 1025 Dokdo Cleanser.
2. Serum. Niacinamide helps balance the look of oil and visible pores. The Beauty of Joseon Glow Serum Propolis + Niacinamide is a lightweight favourite. For redness-prone oily skin, the SKIN1004 Madagascar Centella Ampoule is a calming alternative.
3. Gel moisturiser. Choose a water-based gel that sinks in fast, like the Beauty of Joseon Red Bean Water Gel. It hydrates without a greasy film and sits well under makeup.
4. SPF 50+. Non-negotiable in Australia, every single morning. Oily skin types usually prefer fluid, essence or matte-finish textures. Reapply through the day if you're outdoors.

Tip: Blotting papers do more for midday shine than another layer of powder. Press, don't rub, so you don't disturb your SPF.

What is the best Korean night routine for oily skin?

Night is when you clear the day off properly and do the targeted work.

1. Oil cleanser. Yes, oil, even for oily skin. Oil dissolves sunscreen, makeup and sebum far better than water alone. Massage onto dry skin, add water to emulsify, then rinse. Browse Banila Co for cleansing balms that rinse clean. New to this step? Read our Double Cleansing 101 guide.
2. Water-based cleanser. Follow with a gel or foam. On congested nights, the Innisfree Jeju Volcanic Pore BHA Cleansing Foam or the Some By Mi Super Matcha Pore Clean Cleansing Gel give a deeper clean.
3. BHA exfoliant (2–3 nights a week). BHA is oil-soluble, so it works inside the pore to help clear built-up sebum. The COSRX BHA Blackhead Power Liquid is the classic pick. Start with two nights a week and build up.
4. Hydrating serum. On non-BHA nights, layer something purely hydrating, like the Torriden Dive-In Low Molecule Hyaluronic Acid Serum.
5. Moisturiser. Your gel moisturiser again, or the Laneige Water Sleeping Mask a few nights a week for an extra drink of hydration without heaviness.

Weekly extra: Once a week, swap the BHA for a clay mask such as the Some By Mi Super Matcha Pore Clean Clay Mask. Ten minutes is plenty; don't let it crack dry.

What are the most common mistakes with oily skin?

• Skipping moisturiser. Dehydrated oily skin is common. Swap heavy creams for gels rather than dropping the step.
• Over-exfoliating. Daily scrubs or BHA every night can leave skin red and sensitised. Two to three times a week is plenty for most people.
• Harsh, high pH washes. That squeaky-clean feeling means your barrier is stripped. Stick to low pH formulas.
• Layering too many products. In summer, fewer, lighter layers beat a ten-step routine.
• Going light on SPF. Oily skin still needs a full amount every morning. Choose a texture you like so you actually use enough.

FAQs

Is Korean skincare good for oily skin? Yes. Korean skincare focuses on lightweight, water-based hydration and gentle low pH cleansing, which suits oily skin well. Gel moisturisers, essences and niacinamide serums are staples of the category.

Should oily skin use a moisturiser? Yes. Oily skin can still be dehydrated, and stripped skin often looks oilier. A lightweight gel moisturiser hydrates without leaving a greasy finish.

Can I double cleanse with oily skin? Yes. An oil cleanser dissolves sunscreen and sebum, then a water-based cleanser removes what's left. Double cleanse at night only; one gentle gel cleanse is enough in the morning.

How often should I use BHA on oily skin? Start with two to three evenings a week. If your skin stays comfortable after a few weeks, you can increase slowly. Always wear SPF the next morning.

What is the best Korean moisturiser for oily skin? Look for a water gel or gel-cream that absorbs quickly. The Beauty of Joseon Red Bean Water Gel is a popular pick for oily and combination skin.

How many steps should an oily skin routine have in summer? Four to five steps is enough: cleanser, serum, gel moisturiser and SPF in the morning, plus a double cleanse and exfoliant at night.
