Vitamin C and niacinamide are both beneficial for the skin and can be used together. They have the potential to create a synergistic pairing that provides brightening, anti-aging, and protective benefits for the skin
. Niacinamide is known for its skin-restoring properties and its ability to treat various skin conditions with minimal side effects
. Vitamin C is popular for its brightening effects and its ability to support increased brightness and youthfulness of the skin
. When using these ingredients together, it is recommended to layer them or use a product that contains both, and to do a patch test first, especially for those with ultra-sensitive skin or skin conditions like rosacea or cystic acne
. Modern skincare products are generally stable, but it's important to store them away from heat, sunlight, and oxygen
