Personally i use Serums without any intention and allow them to work on their own. It gives me pleasant surprises.
If BALANCE serum can work in 23 ways, what could be better than this, to allow it to work on its own.
When there is severe or acute problem, then one can put specific intention too, like ALL CLEAR SERUM for severe constipation.
Using ALL CLEAR SERUM for pending work or to speed up some wish specifically.
Doing VOB of fatty areas with BEAUTY SERUM or FLAB DOWN SERUM and so on.
