Key Ingredients

Niacinamide

Helps visibly brighten uneven tone and support the skin barrier.

An ivory abstract form with soft, flowing folds rests on a dusty rose seamless surface, casting a gentle studio shadow.

Tranexamic Acid

May gradually improve the look of uneven tone in some leave-on formulas; the evidence is formula-specific and sun protection still matters.

Seven dry amber, apricot, lavender and celadon relief rays spread diagonally across one warm-ivory matte plaster surface beside a tiny coral point.

Vitamin C

An antioxidant ingredient family that can help brighten uneven-looking tone and soften visible dullness.

Translucent lilac faceted forms and pearly spheres arranged on a pale sage surface against a soft blush backdrop.

Melatonin

An antioxidant ingredient that supports a healthy-looking, more even-looking complexion.
