If you have oily skin, you're likely familiar with the shiny appearance and enlarged pores, especially in the T-zone (forehead, nose, and chin). Oily skin results from overactive sebaceous glands, which produce excess sebum. While this natural oil helps to keep skin moisturized, too much of it can lead to clogged pores, blackheads, and acne. To manage oily skin effectively, it's crucial to use the right skincare products and active ingredients.
Key Considerations for Oily Skin
When choosing products for oily skin, here are some essential points to keep in mind:
1. Non-Occlusive and Non-Comedogenic Products: Avoid heavy, oil-based products that can trap oil in the pores and lead to breakouts. Water-based formulations, especially moisturizers, are ideal for oily skin.
2. Avoid Over-Drying: While it might be tempting to use alcohol-based products to dry out excess oil, this can backfire by triggering your skin to produce even more sebum. Instead, focus on balancing your skin's oil production.
3. Protect Your Skin Barrier: Harsh physical exfoliants can damage the skin barrier, leading to increased sensitivity and oil production. Opt for gentle chemical exfoliants instead.
Now, let's dive into the best active ingredients for oily skin and some top Korean skincare product recommendations.

Top Active Ingredients for Oily Skin
1. Chemical Exfoliants: AHAs and BHAs
AHAs (Alpha Hydroxy Acids): Water-soluble acids that work on the skin's surface to exfoliate dead skin cells and promote cell turnover. AHAs are excellent for improving skin texture and brightening.
BHAs (Beta Hydroxy Acids): Oil-soluble acids that penetrate deeper into the pores, making them perfect for oily and acne-prone skin. BHAs, like salicylic acid, help unclog pores and reduce inflammation.
K-Beauty Recommendations:
COSRX - AHA/BHA Clarifying Treatment Toner: A cult favorite that gently exfoliates, refines pores, and promotes clearer skin.
Isntree - Chestnut BHA 2% Clear Liquid: Contains BHA to deeply cleanse pores and hyaluronic acid to keep skin hydrated.
APLB - AHA BHA PHA Centella Ampoule Serum: Combines AHAs, BHAs, and PHAs with soothing centella to exfoliate without irritation.
SOME BY MI - AHA, BHA, PHA 30 Days Miracle Cream: A multitasking cream that exfoliates, soothes, and moisturizes, perfect for daily use. Although the cream is my favorite, this line includes a variety of products including some specifically for the body, which is great!
2. Hyaluronic Acid
Description: Hyaluronic acid is a powerful humectant that attracts and retains moisture in the skin. Despite having oily skin, hydration is essential, as dehydrated skin can produce even more oil to compensate.
K-Beauty Recommendations:
Isntree - Ultra-Low Molecular Hyaluronic Acid Toner: This toner contains low molecular weight hyaluronic acid that penetrates the skin deeply for optimal hydration.
COSRX - The Hyaluronic Acid 3 Serum: Helps repair the skin barrier while providing long-lasting hydration.
Isntree - Hyaluronic Acid Aqua Gel Cream: A lightweight, water-based moisturizer that hydrates without clogging pores. It comes also in a night mask version to hydrate more intensely during the night without using occlusive ingredients.
COSRX - Hyaluronic acid intensive cream: another great lightweight moisturizer option.
Isntree - Ultra-Low Molecular Hyaluronic Acid Mask Set: A sheet mask set for a hydrating boost when your skin needs it.
3. Niacinamide
Description: Niacinamide is a form of vitamin B3 that helps regulate oil production, reduce pore size, and improve overall skin texture. It's also effective in calming inflammation and reducing redness.
K-Beauty Recommendations:
COSRX - The Niacinamide 15 Serum: Highly concentrated, with added zinc to prevent acne.
Isntree - Hyper Niacinamide 20 Serum: Contains niacinamide, zinc, and hyaluronic acid for a balanced, acne-fighting and hydrating formula.
APLB - Zinc Niacinamide Ampoule Serum: An affordable option that combines niacinamide and zinc for clear, balanced skin.
4. Retinoids
Description: Retinoids, derivatives of vitamin A, promote cell turnover, prevent buildup in the pores, and help reduce the appearance of fine lines and wrinkles. They’re excellent for oily and acne-prone skin but can be irritating, so start with lower concentrations.
K-Beauty Recommendations:
COSRX - The Retinol 0.1 Cream: A low-concentration retinol cream, great for beginners.
SOME BY MI - Retinol Intense Reactivating Serum: Combines different retinoids, including bakuchiol (the main natural alternative to retinol), for a powerful yet gentle effect.
Isntree - Hyper Retinol EX 1.0 Serum: A higher concentration retinol serum with soothing ingredients to minimize irritation.
5. Clay-Based Products
Description: Clay masks help absorb excess oil and draw out impurities from the pores. However, they should be used sparingly (no more than once every 1-2 weeks) and left on for no longer than indicated on the packaging to avoid over-drying and irritating the skin.
K-Beauty Recommendations:
Isntree - Mugwort Calming Clay Mask: Contains calming mugwort, making it suitable for sensitive oily skin.
Anua - Heartleaf Pore Clay Pack: Combines the oil-absorbing power of clay with the soothing properties of heartleaf.
G9SKIN - Color Clay Carbonated Bubble Pack: A fun, bubbling clay mask that cleanses and exfoliates.
SOME BY MI - Charcoal BHA Pore Clay Bubble Mask: Combines BHAs and charcoal for a deep-cleaning, exfoliating experience.
innisfree - Jeju Volcanic Pore Clay Mask Original: A timeless classic for absorbing oil and tightening pores.
