PRODUCT DETAILS

Hello, brighter-looking skin. This facial serum centers 20% niacinamide alongside tranexamic acid and glutathione. With consistent daily use, the formula helps visibly reduce the appearance of pigmentation and promote a more even, radiant-looking complexion. Focused care for dark spots and uneven-looking tone gives it a clear place in a tone-focused routine.

The formula also includes the brand-named Triple Centella Complex: asiaticoside, madecassic acid and asiatic acid. Together, they help calm visible redness, soothe irritated-feeling skin and support the skin barrier.

Hyaluronic acid brings hydration without a heavy feel. You get a lighter way to add moisture while the rest of the formula stays focused on visible tone and redness.

The texture is watery and lightweight, and it absorbs quickly. It leaves a non-sticky finish with no residue, so you are not left with a tacky serum layer. The formula is dermatologically tested and described as suitable for sensitive skin types.
