Tea Tree: Australia's Own Blemish Ingredient, K-Beauty Style

Tea tree is about as Australian as it gets, so it's fun to see it front and centre in Korean blemish care.

What is tea tree?

Tea tree oil comes from the leaves of Melaleuca alternifolia, native to New South Wales. It's used in skincare to purify and help oily, blemish-prone skin look clearer. Korean formulas often use it in small amounts alongside soothing ingredients.

What it does for your skin

• Purifying. It helps oily skin feel cleaner and fresher.
• Clearer-looking skin. Many people use it to help blemishes look less noticeable.
• Refreshing. It gives a cool, clean feel.

Who it suits

Oily and blemish-prone skin. Sensitive skin should choose low-strength formulas.

How to use it

1. Use a tea tree spot product directly on blemishes.
2. Or use a tea tree toner or lotion across oily areas.
3. Never apply undiluted essential oil straight to skin.

When you'll notice it: Blemishes look calmer within a few days.

Good to know: Tea tree can irritate sensitive skin, so patch-test first.

What to pair it with

Pair with cica, panthenol and niacinamide to keep skin calm.

Myth vs fact

Myth: Pure tea tree oil works better.
Fact: Undiluted oil can irritate skin. Well-formulated products use it at gentle levels.

How to choose one

• Look for Melaleuca Alternifolia (Tea Tree) Leaf Oil or Leaf Water.
• Spot products are for single blemishes. Toners or lotions are for oily areas.
• Tea tree leaf water is gentler than the oil.

Where to find it
