## Features

- BYE BYE DARK SPOTS - This hyperpigmentation serum is your secret weapon to fight skin discoloration. Formulated with 4% niacinamide and 1% ethyl vitamin C, it helps visibly reduce dark spots and improve skin clarity in just 8 weeks!
- KEY INGREDIENTS - While pure vitamin C & niacinamide are two powerful, tone-evening, discoloration-fighting molecules, they cannot be formulated together in one product. Instead, we use a highly stable, bioavailable vitamin C derivative.
- SKIN-LOVING FORMULA - IT Cosmetics Bye Bye Dark Spots Niacinamide Serum is your solution for age spots, melasma, and other types of discoloration. 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 onto clean skin, using fingertips. Press serum into entire face and neck, avoiding eye area. Follow with Confidence in a Gel Lotion Moisturizer and, in the AM, CC+ Cream with SPF 50+.
- IT REALLY WORKS - With clinical insights from plastic surgeons, plus ingredient and skincare expertise from dermatologists, IT Cosmetics creates problem-solving products that give you real results!
