You see products with 10 percent aha, some with 6 percent some with 12 with different brands. My question is are they all the same no matter what brand they are? So if one product uses 10 percent aha and is from A company and another uses 10 percent aha from B company... aren't the aha suppose to be the same or will it be bit different b/c not all ingredients are 100 percent the same?

The same with chemical peels. Does it matter which company TCA or glycolic acid peel you buy? Such as 30 percent glycolic peel from skin obsessions vs paulas choice... does it really matter since its both 30 percent? shouldn't they both work the same?
