Korean moisturisers and toners for oily skin: what to look for

The biggest misunderstanding about oily skin: "moisturiser will make it oilier." The opposite is true. Dry the skin out and it makes more sebum to compensate. The goal is not zero oil; it is water without oil.

Toner: what to look for

• Alcohol-free. Alcohol feels matte at first, then dries the skin and the oil climbs.
• Ingredients: niacinamide (oil and pores), tea tree or heartleaf (calming), PHA or mild BHA (clear pores), a little witch hazel.
• Texture: watery; "milky" toners are for dry skin.
• Picks: Medicube Zero Pore Toner 250ML, SKIN1004 Madagascar Centella Tea-Trica Purifying Toner 210ml

Moisturiser: what to look for

• Gel or gel-cream, labelled "oil-free" or "lightweight".
• Ingredients: hyaluronic acid, glycerin, centella, niacinamide; a little ceramide is fine.
• Avoid: heavy butters (shea), coconut oil, mineral oil high up the list.
• Picks: IUNIK Centella Calming Gel Cream 60ml (gel cream), Anua Heartleaf 70 Daily Lotion 200ml (lotion, for the body too)

The routine

1. 1Morning: low-pH gel cleanser → toner → gel moisturiser → matte sunscreen — Anua Zero-Cast Moisturizing Finish Sunscreen SPF 50 50ml
2. 2Night: double cleansing → toner → (BHA two or three nights a week) → gel moisturiser
3. 3Shine at midday: blotting paper, not powder; powder settles into pores.

The truth about pores

Pore size is genetic; "pore minimising" products do not shrink pores, they keep them clear so they look smaller. Regular BHA and sunscreen: that is as far as it goes.

Dehydrated oily skin

Shiny, yet tight after washing, sometimes flaky: low on water, high on oil. The fix: two layers of hydrating toner, a light moisturiser, an even gentler cleanser. Stop strong actives for two weeks.
