i bought certain dri yesterday n i would like 2 knw how long it will take 4 certain dri 2 take its full efect?

Answer 1

I bought the CVS brand comparable to Certain Dri & it worked immediately. If it didn't work right away, maybe your body will adjust and it will just take a few days. Make sure you follow the directions and do not shave before using. I made that dreadful mistake & suffered horribly!

Answer 2

I don't know if you bought the day or night formula, but I use the night time roll on during the warm months. It usually takes 3-4 days. Lasts for a few weeks and I go through the cycle again. i still use deodorant though, just in case. Its so nice not to have wet marks under my arms!
