PRODUCT DETAILS

When your skin looks red or feels irritated and shiny at the same time, this facial serum keeps the care simple. It brings cooling, soothing comfort together with hydration and oil-balancing care, helping your complexion feel fresh without leaving a sticky finish.

Its lightweight, fast-absorbing texture settles into a fresh, non-sticky feel. The serum also helps control excess oil for a balanced, matte finish, making it a considered choice when shine is part of the picture.

Willow bark extract supports a more refined-looking finish when clogged pores are a concern. Houttuynia cordata and Centella asiatica add soothing support for the look of redness and irritation.

For sensitive skin, this serum has a lightweight, fresh finish. The ingredient list includes plant-fermented ethanol, Damask rose flower water, lemon-scented tea tree oil and citral. Some reviewers described the scent as strong or alcohol-like, while others found the serum was not moisturizing enough—helpful context if richer moisture or a low-scent routine matters to you.
