  1. Terry McFarlane

    Whitened my teeth real good, no pain either which i’d had previously with stuff from the US

  2. Evie

    So far I’m really happy with the product but I haven’t been sent any information about how to use all 3 products alongside each other. Also it isn’t clear how much gel should be used for one application, it just says to apply quarter and I’m unsure if that is a quarter for top and bottom or a quarter each! I can definitely tell the product is working though!

    Started using the LED box first and noticed some changes, started using the powder which was much better. THEN omg the whitening strips are amazing! After first use I saw a massive change..however, super strange that there is so little information on how often to use each product and how to use them alongside each other when buying the complete set..even online?!?

      Hi Cleo! great news on the results :-), you should have had a full instruction guide included to use all the products and in which order (but it sounds like you have done it correctly yourself 🙂 ), apologies if the leaflet was not included “:-)

    This product is nothing short of amazing. I have tried dozens of things, ranging from crest strips to some dodgy online (seemingly illegal in the UK) peroxide based gels, and non of them have come close to the effectiveness of Smirk. I’m 2/3 way through the box and already my teeth, which were stained on top and underneath of the enamel, are several shades whiter. I’ll be making a video review soon and putting it on YouTube. Thanks so much Smirk!
