Could it be irritant/exfoliant in 0. 2- 0.4% ?

Could it be irritant/exfoliant in 0. 2- 0.4% or is this percentage used to the pH? And is it safe to mix it with vitamin c in the morning? Thx

Ingredient: Citric acid

In theory, it could - but it is not very likely. If used for pH balancing, citric acid usually does not cause any trouble. Re mixing - if you mean using a product with citric acid in this concentration in one step with another product with vitamin C - then, yes, shouldn't cause any issues. (Just in case you meant actually mixing in an ascorbic acid powder into another product, then it's not a good idea.)

I was not very clear. I meant using a product with this concentration in citric acid and than another product with vitamin C. Thank you for your answer :)
