The Snow Kit is an AMAZING PRODUCT! I’ve struggled with confidence, depression, anxiety, and yellow teeth all my life. I’ve gotten them whitened at the dentist as it’s throwing money away! I have tried every way imaginable to whiten my teeth before Snow and every product I could find. Don’t waste anymore money or anymore time! Invest in yourself and buy Snow! I gained so much confidence with white teeth I love to smile now! It actually, truly, helped big time with my depression and anxiety bc it’s hard to be down when you Love to smile and love your smile with white teeth! THESE ARE MY HONEST TO GOD REAL RESULTS AFTER FOLLOWING THE SIMPLE DIRECTIONS (except I used the extra strength serum since the beginning after buying a bunch of extra pens). My pictures aren’t in order, but follow the khaki teeth to the whitest and I told you I love to smile now!
