Advanced Whitening Arvostelua 

It is not a legitimate company. Order 05/08 did not arrive and no response or communication. I would never ever engage with them again.

This company is a scam ,ordered 9/4/26 never arrived but £31,41 taken from bank 10/4/26, no reply to emails , absolutely shocking ,
Just received my crest strips today .has taken 3 weeks to arrive .poor service .but I got them

Do not order from this company , I never received my order and they could confirm where it had been delivered. There resolve was to reorder and then they would refund which I find weird, probably would get the refund the delivery . DO NIT ORDER FROM THEM ITS A SCAM

If I could, I would give this company zero stars. Ordered in October 2025 and was never sent a tracking number. After a few emails, Xanthe finally sent the tracking info but the strips never arrived. I also wasn’t aware at the time of ordering that it’s shipped from China, not the UK. Anyway, the order never arrived and when I emailed Xanthe and customer care, they wanted me to repurchase and after I did that, I would get my refund. I said I wasn’t comfortable to do so and all communication stopped. Do not buy from this company.

They are a SCAM. I placed an order for whiteners in early October and have yet to receive them.

I have sent numerous emails to Xanthe with false promises of stock shortages and it would be arriving. I have requested the order to be cancelled and my money returned. To date nothing has happened.

I will be reporting them to the relevant authorities as fraudsters and scammmers.

PUBLIC BEWARE - THEY ARE CON ARTISTS

Ordered in belief it was UK company,however they are chinese and whether I get them or not I wouldn't have ordered from the dodgy website

Ordered 17th October. No tracking number, no order received. Company not responding to emails. Yet sending me lots of ads.

If I could give 0 stars I would. Avoid like the plague!

Ordered teeth whitening strips on 20th October, emailed on numerous occasions for tracking information, alot of back and forth, to then be emailed on 30th October saying they had "sorted" it.

Absolute shambles, and honestly wouldn't waste your money. Worst customer service I have ever experienced ordering whitening strips. Never again!

"SCAMMERS!"A month later no Whitening strips back and fore pointless emails no product no refund ** do NOT buy from here**

UPDATE: After numerous unhelpful emails back and forth today I'm told my order was lost by the delivery company and a dispute has been raised with them. Absolute joke, I did not pay the delivery company I paid these scammers. If you've come to TP for advice, save yourself a lot of bother and go to a reputable supplier. These guys are definitely not that.

Took a long time to be delivered as came from China. I've used these now for 3 weeks, and I have to say, I'm suspicious whether or not they're legitimate, although they have definetely made my teeth whiter, they've only made a small difference

Package got held up at foreign customs and never arrived. Emailed about 10 times over 6 months never got a reply or refund.

I was very worried after I had ordered the Crest whitening strips from their website after reading the reviews on here. I also never received the tracking details in my inbox.

I emailed them and they got back to me within two days with the tracking details and the strips arrived after two weeks, via Holland.

I’m very impressed with the product and they really do work. The team at Advanced Whitening also contacted me to ensure I had received my package and provided me with a discount code on a future order.

Order regularly and so do my family. Great products and always areive on time. They forgot to post my free promotional strips but emailed offering to compensate me for this so cannot complain! Thanks

Item didn't arrive. Contacted them about this and initially received a reply but they're ignoring my emails now. Please avoid this company, they're either scammers or they just have really poor customer service skills.

Ordered crest professional luxe whitening strips they arrived within a week, I had communication from them whenever I had a queries and the product is brilliant, my teeth were stained from drinking Coca Cola every day for years, I’ve only used strips 4 times and people are commenting on my white teeth, I’ll definitely order from them again 😀

Ships from china not the uk as stated on their website,do not buy .

Ordered! Nothing has arrived!!!!

Ordered whitening strips which never arrived. I sent 8 unanswered emails to their customer service and tried to get in touch through their website but no response. Paid this company and can’t get money back or the product I ordered.

These arrived nice and quickly . There are so many fakes and scams out there and I have lost lots of money this way so I was very happy that these were genuine and worked well . They don’t come in original packaging however but definitely the genuine article . I’m unable to buy the crest supreme strips now in the UK and whilst these are less effective and take a bit longer to achieve the desired result , they definitely do the job and don’t cause so much sensitivity . I’d trust this company and will re order
