PRODUCT DETAILS

Hello, clearer-looking tone. This facial serum focuses on the look of uneven tone, dark spots and discoloration, with clarity and brightness as its main goals.

At the center are 5% tranexamic acid and 5% niacinamide. Tranexamic acid helps reduce the appearance of hyperpigmentation and improve the look of tone, while niacinamide supports a brighter, more even appearance. Niacinamide also brings barrier support and helps skin look less oily and more balanced, so the formula offers more than tone care alone.

Hydration isn't left out. Sodium hyaluronate supports hydration and the look of elasticity, while aloe leaf extract brings moisturizing and soothing care. Together, they give this targeted serum hydrating and soothing support.

The texture is clear and watery, with a lightweight, fast-absorbing and non-greasy feel. It is designated for all skin types, keeping its focused tone care in a light-feeling format.
