Key Ingredients and Their Potential Benefits
1. Mandarin for Brighter-Looking Skin
Mandarin-derived ingredients are often included in skincare formulations for their antioxidant properties. Depending on the specific ingredient used, they may help support the skin’s appearance and protect against oxidative stress.
The serum’s advertised 11% mandarin concentration makes it an important part of the product’s brightening-focused formula. However, results depend on the exact ingredient, formulation, and individual skin type.

Niacinamide, a form of vitamin B3, is a popular skincare ingredient known for supporting the skin barrier and improving the appearance of uneven skin tone.
The serum contains 5% niacinamide. This ingredient may help reduce the appearance of dark spots over time, support moisture retention, and improve the overall appearance of skin texture.
Consistent use and daily sunscreen application are important when working toward a more even-looking complexion.
