COSRX BHA Blackhead Power Liquid — The Pore-Clearing Gold Standard

Best for: Oily skin with blackheads and congested pores
Key ingredients: 4% Betaine Salicylate (BHA), Willow Bark Water, Niacinamide
Price range: $18–$25 on Amazon

This exfoliant uses 4% betaine salicylate — a gentler BHA derivative that penetrates oil-filled pores without the irritation of traditional salicylic acid. The willow bark water base provides natural anti-inflammatory support while niacinamide works to regulate sebum production over time. Clinical testing by COSRX showed visible pore reduction within two weeks of daily evening use. It suits oily and combination skin types best, though those with sensitive-oily skin should start with every-other-day application.

Anua Heartleaf 77% Soothing Toner — Calm Oily Skin Without Heavy Layers

Best for: Oily-sensitive and combination skin
Key ingredients: 77% Heartleaf (Houttuynia Cordata) Extract, Panthenol, Hyaluronic Acid
Price range: $16–$22 on Amazon

Anua's breakout toner contains 77% heartleaf extract, a traditional Korean medicinal herb shown in published dermatological studies to reduce redness and regulate oil production. The watery consistency absorbs in seconds — no tacky residue, no pilling under sunscreen. Panthenol strengthens the moisture barrier so your skin stops overproducing sebum as a compensation response. This is the go-to toner for anyone whose oily skin gets reactive with typical astringent formulas.

Some By Mi AHA BHA PHA 30 Days Miracle Toner — Triple-Acid Acne Fighter

Best for: Acne-prone oily skin needing exfoliation
Key ingredients: AHA (Glycolic Acid), BHA (Salicylic Acid), PHA (Gluconolactone), Tea Tree
Price range: $14–$20 on Amazon

This toner combines three chemical exfoliants at mild concentrations — AHA dissolves dead surface cells, BHA clears inside pores, and PHA provides gentle exfoliation even for beginners. The 10,000 ppm tea tree extract adds antibacterial action against acne-causing P. acnes bacteria. Some By Mi reports that 92% of trial users saw improved skin texture within 30 days. Ideal for oily skin with recurring breakouts, though it pairs poorly with retinol — use one or the other, not both.

COSRX Low pH Good Morning Gel Cleanser — The 5.5 pH Oil-Control Wash

Best for: Daily AM cleansing for all oily skin types
Key ingredients: 0.5% BHA (Betaine Salicylate), Tea Tree Oil, Cocamidopropyl Betaine
Price range: $9–$14 on Amazon

Most foaming cleansers strip oil and leave skin tight — this gel cleanser maintains a pH of 5.5, matching your skin's natural acid mantle. The low-dose BHA provides mild daily exfoliation during your morning wash without over-drying. Tea tree oil offers gentle antibacterial benefits, while the mild surfactant system creates enough foam to feel clean without disrupting your barrier. At under $14, it is the most cost-effective entry point in any K-beauty oily-skin routine.

Torriden DIVE-IN Low Molecular Hyaluronic Acid Serum — Weightless Deep Hydration

Best for: Dehydrated oily skin that needs moisture without oil
Key ingredients: 5 Types of Hyaluronic Acid (50,000 ppm), Panthenol, Allantoin
Price range: $15–$22 on Amazon

Oily skin still needs hydration — and this serum delivers it through five molecular weights of hyaluronic acid that penetrate different skin layers. The completely oil-free, fragrance-free formula has a water-like texture that absorbs instantly under sunscreen or makeup. Torriden uses low-molecular HA (under 50 daltons) that reaches deeper than standard HA, addressing dehydration that triggers excess oil production. Dermatologists frequently recommend this for oily types who mistake dehydration for oil overproduction.

Innisfree No Sebum Mineral Powder — All-Day Matte in a Compact

Best for: Midday shine control and makeup setting
Key ingredients: Jeju Mineral Powder, Mint Extract, Sebum-Absorbing Silica
Price range: $8–$12 on Amazon

This cult-favorite loose powder uses Jeju volcanic mineral powder and silica to absorb excess sebum on contact — one application keeps shine under control for four to six hours. The micro-fine particles are translucent and work across all skin tones without flashback. Mint extract provides a cooling sensation that tightens pores visually. It works as both a makeup-setting powder and a standalone oil blotter, making it the most versatile product on this list for anyone dealing with midday grease.

Skin1004 Madagascar Centella Ampoule — Soothe Breakout Damage Fast

Best for: Post-acne redness and irritation on oily skin
Key ingredients: 100% Madagascar Centella Asiatica Extract, Madecassoside, Asiaticoside
Price range: $16–$24 on Amazon

This single-ingredient ampoule contains 100% centella asiatica extract sourced from Madagascar, where the plant produces higher concentrations of active compounds due to the soil conditions. Madecassoside and asiaticoside — the two key triterpenoids — stimulate collagen synthesis and reduce inflammation, which is why dermatologists often recommend centella for post-inflammatory hyperpigmentation. The texture is essentially water, with zero oils or emollients that would clog oily skin. It layers effortlessly in a multi-step routine and works exceptionally well after chemical exfoliants to calm any irritation.
