Quickly works
I noticed a difference right away.  It was very noticeable on the second day.  The only issue I have is my lips are very sensitive to the product.  My bottom lip swelled up the first day but now I'm on day 3 and I guess I'm getting used to it because I'm not having anymore swelling.  Even if the swelling continued I would continue to use it because of the difference I'm seeing,it's worth a little bit of swelling lol.  I will continue to purchase this product because of the results you get.  I tried Crest white straps and I noticed right away my gums were burning and my teeth became so sentiment I couldn't continue using  them.  This product works without that abuse. If you've been thinking king about getting these whiteners, don't wait another day go for it.
