Here’s a quick summary of how our products will find their way to your door:

UK Mainland

All orders over £25 - free Standard Post.

For all orders under £25, the following tariff applies (depending on how quick you want your goodies):

Standard Post - UK 2nd Class Post - £3.00 (This takes between 2 to 3 days). Please note that we cannot accept responsibility for lost packages when using this option.

Express Post - UK 1st class - £4.00 (1-2 days). International If you live in a land far, far away, don’t worry, you can still make your statement with Beautyuk*. It does cost slightly more as the carrier pigeons need more food for long journeys.

We aim to dispatch all orders within 48 hours. Orders received on Fridays after 12 noon will be dispatched on the following Monday. We will always do our best to get orders out on time and sometimes this will be earlier than stated, however, on occasion, due to unforeseen circumstances, there may be a slight delay for which we apologise.

If for some reason you haven’t received your order and the date when it should have been received has passed, maybe give it a day or two in case the postman got lost, then email and we will do our best to locate your order.

Strengthened and helped grow my nails

My nails were quite damaged after having UV Gel nails.
I've been using this for a couple of months and it really has helped my nails grow.
And so much stronger than they were

my new favourite product

my nails crack and peel very easily, this makes them flexible and super shiny. I have been wearing it alone without any colour because it just makes my nails look so healthy!

Really helped my nails

I've been using this product for about 3 months now and I can honestly say my nails have never looked and felt so good.

I have very brittle nails and this Hardener has strengthened them and they have started to grow really nicely.
