AHAs and BHAs, such as glycolic, salicylic, and lactic acids should never be used with Vitamin C. Vitamin C is an acid, too, and is unstable, so the pH balance will be thrown off by layering these ingredients together and might as well be useless.
“AHAs and BHAs can certainly be combined. For example, for oily skin, a salicylic-based cleanser can be used followed by a glycolic acid toner. Generally, a glycolic acid is great for dry, dehydrated or combination skin, whereas salicylic acid would be perfect for oily/spot-prone/acne skin.
Niacinamide & Salicylic Acid

Niacinamide tends to work best in an environment with a neutral pH and because salicylic acid is, well, an acid it does not have a netural pH – it has an acidic one.
