Tea tree extract helps refresh oily and blemish-prone skin, while niacinamide supports a brighter and more even-looking tone. Together, these ingredients help improve the appearance of stressed skin and post-blemish marks without making the complexion feel overloaded.
How to Use This Calming Face Mask

- Follow with moisturiser if additional hydration is required.
Triple-Layer Plant Cellulose Sheet
Each sheet is constructed with three layers of naturally derived plant cellulose to help hold and distribute the essence across the skin. The close-fitting material supports comfortable application and allows the formula to remain in contact with the complexion throughout the treatment.
