i wud like the sebum gel...is it 119 after discount? can cod?

Hi i bought the sebum gel from you recently but using for 1over week, notice its not as effective as the old packing gel. Any difference in the concentration? Previously the whiteheads/pimples would dry up almost immediately after 1st appl, now after 1over week still havent dry up. Am not doubting your products, just whether cellnique have changed their product concentration.
