65.6% tea tree leaf water
Calms troubled areas, refreshes oily skin and supports a clearer-looking complexion without the harsh feel of an intensive spot treatment.
TEA TREE RELIEF SERUM
This lightweight water-based serum combines 65.6% tea tree leaf water and 19% centella asiatica leaf water—84.6% of the formula—to calm sensitive, troubled skin while keeping oil and moisture comfortably balanced.
Niacinamide and beta-glucan reinforce barrier care and improve the look of uneven tone. Six sprout extracts add moisture and nourishment, leaving skin smoother, more supple, clearer-looking and softly dewy without a sticky finish.
Skin can feel oily on the surface yet dry and tight underneath. This serum replenishes lightweight moisture while calming discomfort and balancing excess oil and sebum, making it practical for humid-weather routines and skin that reacts easily.
Use it when skin looks congested, uneven or rough, or when blemishes leave the complexion looking less clear. The calming, moisturising formula is suitable for all skin types, with particular value for oily, combination, sensitive and blemish-prone skin.

Tea tree leaf water delivers daily soothing care for troubled areas and keeps skin feeling fresh and clean. Centella asiatica leaf water and centella extract calm sensitive, irritated-feeling skin and restore a healthier-looking balance.

DAILY RELIEF + HYDRATION
The formula handles three needs at once: tea tree leaf water refreshes blemish-prone areas, centella restores calm and beta-glucan replenishes water while reinforcing the barrier. Niacinamide completes the routine by improving excess sebum and uneven-looking tone.

Wheat sprout, broccoli, alfalfa, cabbage leaf, radish seed and rapeseed extracts provide abundant moisture and nutrition. This six-sprout complex works with humectants and calming ingredients to soften rough texture without weighing the skin down.
