How it works

The panel on this serum names four forms of tea tree rather than one: Melaleuca Alternifolia (Tea Tree) Leaf Water, Melaleuca Alter-nifolia (Tea Tree) Leaf Oil, Melaleuca Alternifolia (Tea Tree) Extract, Melaleuca Alternifolia (Tea Tree) Leaf Extract. Tea Tree Leaf Water is the distillate, used in place of plain water as a base. It carries a trace of the plant's aroma and none of the essential oil's strength. On this panel it sits alongside Allantoin. Allantoin is a comfrey-derived compound used to condition skin and soften the outer layer so it feels smoother. It is one of the standard additions to a formula built for easily irritated skin.

Key benefits

  • Four forms of tea tree on one panel, not a single token inclusion
  • Allantoin on the same panel, the formula's active
  • 40 ml to a unit
  • Korean GS1 barcode matched against a Korea sourcing supplier's record for this item

Key actives

Melaleuca Alternifolia (Tea Tree) Leaf Water

Tea Tree Leaf Water is the distillate, used in place of plain water as a base. It carries a trace of the plant's aroma and none of the essential oil's strength.

Melaleuca Alternifolia (Tea Tree) Extract

Tea Tree Leaf Extract is the water-based extract rather than the essential oil, so it is far milder and much less aromatic. It is used in formulas for blemish-prone skin.

Allantoin

Allantoin is a comfrey-derived compound used to condition skin and soften the outer layer so it feels smoother. It is one of the standard additions to a formula built for easily irritated skin.

Payment and security

We accept

How to use

  1. Apply after toner while the surface is damp so a few drops cover the whole face.
  2. Press it in with flat fingertips rather than rubbing it around the face.
  3. Follow with a light moisturiser once it has settled for about a minute.
  4. Do not introduce it in the same week as a new acid, since you will not know which one caused a reaction.

Worth knowing

  • Patch test on the inner arm before first full use, as with any new skincare product.

What professionals say

What professionals say

What skin-care professionals say about the key actives in this formula, quoted from the medical sources linked beside each.

  • Allantoin can tone down the dryness of the individual cells. It increases the water content of the skin, which means it helps to hydrate and moisturize.

  • I think it's fair to say I've seen lots of patients use tea tree oil for a variety of skin issues. It's a natural remedy that is known to help.
