after 2 weeks of taking it, with no improvement, and then calling my doctor-only to find out it was not right! Walmart gave me the wrong stuff. Whoops , they said, come in and get the right stuff. ha, I paid $80.00 for the first wrong one, that messed my face up, and then then they expected me to pay $140.00 for the real one? They ended up giving me the second, no extra charge. But, I am not going to spend all that extra money for an attorney, it was pimples. And it seems, like faces are not an important commodity, whatever.
