Oz : Beauty & Personal Care Review: Excellent product for dark spots - Used this for a few weeks (not sure how long because in all honesty I just used it not thinking it’d work) Then one day I was washing my face and could barely see the spots I’d been targeting. Ordering again to finish these little dark sun spots off my face. Will update later. I mixed this with hyaluronic acid (same brand) applied on face with special focus on dark spots and saw significant difference. Review: IT Cosmetics Really Work - I love all the IT Cosmetics line! After using for 3 months, my dark spots are not gone, but they are less noticeable. ## Features - BYE BYE DARK SPOTS FACE SERUM - This niacinamide & vitamin C face serum is your daily remedy for dark spots. 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 to formulate our discoloration correcting serum. - 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08YBVSPSG | | ASIN | B08YBVSPSG | | Active Ingredients | salicylic_acid | | Best Sellers Rank | #67,629 in Beauty & Personal Care ( See Top 100 in Beauty & Personal Care ) #1,376 in Facial Serums | | Brand Name | IT Cosmetics | | Customer Reviews | 4.2 4.2 out of 5 stars (908) | | Global Trade Identification Number | 03605972655363 | | Is Discontinued By Manufacturer | No | | Item Form | liquid | | Item Volume | 30 Milliliters | | Item Weight | 0.03 Kilograms | | Item model number | TT3605972655363 | | Manufacturer | IT Cosmetics | | Manufacturer | IT Cosmetics | | Manufacturer Part Number | 3605972655363 | | Model Number | TT3605972655363 | | Number of Items | 1 | | Product Benefits | Helps visibly reduce dark spots, melasma & other types of discoloration.
