None smoker with slight yellowing from coffee. No change in whiteness. Waste of money and left teeth sensitive if used more than once a day
I've been using this charcoal kit for the last couple of days with zero complaints! Taste is good and it’s easy to use.
My teeth brightened up after using this whitening kit for 6 days!! I’m going to continue using! Thank you Smiletime!
I like that this strips are cheaper but more effective than other brands don’t leave my teeth feeling sensitive!
This premium top up set is a must have to a bright smile! This product brings back my confidence to show my smile.
Though i’ve only been using it for a couple days, i can already see a change. It feels like I'm really helping my teeth
I have tried some whitening products before but they cause me pain. Smiletime products gently whitens my teeth. Will definitely be buying this again.
I’ve been using it for a week now and my fiancee noticed a definite difference! I love this product, they make it as easy and painless as it could possibly be.
This refill gels are great because I have sensitive teeth. I signed up for subscription monthly for top up
I have bee using his gels for a week now and I’ve noticed a pretty big difference in how white my teeth are
I finally found something that whitens the spaces and cracks between my teeth! And it doesn’t taste bad at all
I have used this charcoal kit for 10 days and even though my teeth are not perfect I must say in that majority of stains have been removed with no adverse reaction to it.
