Opalescence PF 15% Teeth Whitening 4pk of Mint Flavor Syringes by Opalescence

Really good, does its job, will definitely purchase again

I’ve found this to be the most effective whitener brand and highly recommend it.

This is completely ineffectual. It was 15% which meant the plates had to be in your mouth for 5/6 hours. There was absolutely no difference.

The description explicitly states this is a "kit". It is NOT. It is purely the refill syringes and you are expected to get your own teeth mould. Demanding a refund

جربتها اختي بس حسستها لانها تطول فيها سو انتبهوا لا تطولون فيها

Very good product

LOVE this item! I got the exact same brand from my dentist's office but at a much higher price with them. I found this same brand on Amazon (with different levels of options) at a lower price and knew this is what I needed to get. Comes in 2 packs of 2 syringes. I generally use this every other night (I don't want my teeth to get too sensitive) and the tubes last me a good while. I'd say I can get at least 3 days out of 1 syringe (using on both top and bottom, all teeth). Flavor is decent. Stays put all night in my retainers and actually whitens! I don't have a shade test, but they are many shades whiter now. I am very pleased with this product.

الماده شبه ناشفه او قديمه

I have used this before and it’s a great product. My teeth are sensitive so I go for the lower percentage.
