Thank you to those that stating Niacinamide can use together with vitamin c for skin brightening effect. I’m aware of updated articles that support this claim. However, I tried it in the past those 2 together, doesn’t work for me so I include it here as should not mix for those with sensitive, redness, acne prone and problems skin. ❤️❤️
