On the description for super serum, it says that the niacinamide in the product is incompatible with all acids. Is it completely incompatible with salicylic acid as well? I have a drugstore scrub that I like that has 1% salicylic acid, and was wondering if it would be worth it to try a sample of the super serum. I also found some info on another forum saying that renovage like in awesome sauce, couldn't be used with niacinamide - I know Karen thinks they're overkill to combine, but I also know that a lot of people like to rotate serums. Is either combo safe?
I do know of some that can use Super Serum with low percentage salicylic acid products and others that can't. If you want to try it, please proceed with caution as it is not recommended. I think if you use the niacinimide and Renovage in separate applications, it will be all right. I have done that before without issue. Still, test, test, test. These are some hefty actives, and some can't use them even alone due to sensitivity. I do suggest sampling these types of products first, too.
