- SKIN-LOVING FORMULA - IT Cosmetics Bye Bye Dark Spots Niacinamide Serum is our best facial serum to help you visibly reduce age spots, melasma, and other types of hyperpigmentation. Our dermatologist-tested treatment is suitable for all skin types, even the most sensitive.
- HOW TO APPLY - After cleansing in the AM & PM, apply 4-5 drops of dark spot serum into entire face and neck, avoiding eye area. In the morning, follow with your favorite IT Cosmetics CC Cream for SPF sun protection. At night, layer Confidence in a Gel Cream Oil Control Face Moisturizer on top of facial serum for a boost of hydration.

But it does work

### ⭐⭐⭐⭐ Nice serum
*by S***6 on February 9, 2023*

This serum contains a powerful ingredients for improving overall appearance of the skin. Niacinamide and vitamin C work together to provide many different benefits. Niacinamide( vitamin B3) is a water-soluble vitamin that helps to reduce inflammation, minimize pores, and improve skin texture. Vitamin C, is an antioxidant that helps to brighten the skin, reduce hyperpigmentation, and protect against environmental damage. This serum has reduced my fine lines and has faded dark spots. It is not sticky like other similar serums I have tried in the past.
