i think they do work, i only used them for 2 days but i noticed a real difference. i had to stop tho cuz my gums were killing me, my teeth are too sensitive for the strips :-( sucks cuz i really liked them.
my aunt said she used to use them and they worked really good for her.
Same as above! They totally were working but by day 3 I couldn't take the pain in my gums and my teeth were super sensitve too :-/ I stopped day 3. I used the Go Smile products by Sephora and they work just as good but without the pain and sensitivity to your teeth and gums. A little on the pricier side though.
