wonderful

Frankly I really recommend at the beginning I thought I was going to have weak gums, that it was not going to work but nothing to see its really works and there is a crazy result on the other hand I do not recommend you do it at all every day because personally after doing 1 week every day after putting on a band I have my gum that burned me and I had a little white mark on my gum that went away after but after that I did 2/3 days in a row then I leave 2/3 days and the result and the magnificent and my teeth are not weakened at all.

Great product, results start to be visible after 3rd strips! So imagined at the end of the 21st! The only downside... Sensitizes the gums a lot at first... They are red and painful when you brush your teeth... So I went to the pharmacy and bought gingival paste that I put on after every strip session... And then nickel!

Love Crest whitening strips and from Biovia you know you are genuine products. The supreme are wonderful but personally prefer Professional Effects only because they are 30 mins to wear, otherwise both are excellent.
