Shiny T-zone, midday grease, clogged pores that won’t quit—sound familiar?
If you’re like most women with oily skin, you’ve probably stood in front of the mirror thinking, “Why does my face feel slick before lunch?” Blotting papers, scrubs, even skipping moisturizer—many of us have tried them all. Still, by 2 p.m., the shine is back. The whole cycle is frustrating, exhausting, and honestly? It can make you feel self-conscious in ways no one talks about.

Oily skin doesn’t mean dirty skin. It often comes from your genes, hormones, weather, or skin routine.
Oil glands (sebaceous glands) in your skin can make too much oil—especially when it’s hot or humid.
That oil mixes with sweat and dead skin, blocking your pores and making them look bigger.
When your skin loses bounce and tightness with age or sun damage, pores can stretch and stay open.
📚 Cleveland Clinic explains that too much oil is usually caused by hormones—not poor hygiene.
📚 Harvard Health says oil levels often shift with age, especially for women.
📚 Dermatology Times recommends protecting your skin instead of stripping it with harsh products.
Before we fix oily skin, we need to stop making it worse. These common habits might feel helpful—but they’re secretly keeping your pores clogged and shiny:
Using harsh, foaming cleansers
Stripping your skin causes rebound oil production. You’re making it greasier.
Skipping moisturizer
Dehydrated skin overcompensates by producing more oil. A lightweight, water-based hydrator is essential.
Using alcohol-based toners
Feels clean in the moment but damages your barrier long-term.

Over-exfoliating with scrubs or acids
Weakens the skin’s natural defenses and causes irritation or even more oil.
📚 Healthline on signs of over-exfoliation
Skipping sunscreen
UV damage thickens skin and enlarges pores. Use a gel or fluid-based SPF that won’t clog.
Now that you know what’s making oily skin worse, let’s explore what actually works—straight from dermatologists.
I spent months researching and testing ingredients that dermatologists repeatedly recommend for oily skin—and these five kept showing up. They’re not just trending; they’re backed by science and suggested by experts because they work on a cellular level to calm the skin, reduce oil production, and shrink the appearance of pores. I made sure to include each one in my routine because of what they target—and how effectively they’ve helped me stay balanced.
Niacinamide – A form of vitamin B3 that reduces sebum production, tightens pores, and improves texture. It also helps brighten post-acne dark spots.
👉 The Ordinary Niacinamide 10% + Zinc 1%
Salicylic Acid (BHA) – This oil-soluble acid exfoliates deep inside pores and removes trapped sebum and debris. It’s a favorite for blackheads and T-zone congestion.
👉 Paula’s Choice 2% BHA Liquid Exfoliant
Clay (Kaolin or Bentonite) – Gently absorbs excess oil and detoxifies the skin without over-drying. Regular use helps keep pores clear and tight-looking.
👉 Aztec Secret Indian Healing Clay
Centella Asiatica (Cica) – A plant extract known for calming redness, healing the skin barrier, and reducing inflammation from breakouts or irritation.
👉 Skin1004 Madagascar Centella Ampoule
Green Tea Extract – A powerful antioxidant that reduces oiliness and soothes the skin. It’s lightweight, non-clogging, and great under sunscreen.
👉 Innisfree Green Tea Seed Serum

These are the exact habits I developed while flying around the world—small, consistent routines that still help me stay balanced today:
Blotting paper—but only once a day
More than once triggers rebound oil.
Cold water rinse
Splashing with cold water after cleansing helps tighten pores and refresh.
Hydrate from the inside
I hydrate with caffeine-free herbal teas or electrolyte water daily—it supports oil balance better than you’d think.
Avoid pore-filling primers
Most use silicones that stretch pores and clog. I use hydrating SPF instead.
Weekly reset: Clay mask + calming ampoule
Every Sunday night, like clockwork. It resets my whole face.

Oily skin and large pores aren’t flaws—they’re signs your skin is working hard to protect you. The goal isn’t “no oil.” It’s balance.
Let your skin breathe, treat it with care, and support it with the right ingredients. With consistent habits and less stress, you’ll see your oil level and pore appearance finally settle.
✨ Mijung’s Note: As a former flight attendant, I had to keep my skin photo-ready for long-haul flights, no matter the oil slick happening midair. What I learned over time (with some Korean skincare help!) is that managing oily skin isn’t about stripping your face—it’s about balance. So if your skin feels greasy one hour and tight the next, you’re not alone—and you’re not doing it wrong. This blog breaks it down.
