Hydrating nail and cuticle mask - 14ml / 0.5 fl.oz

Fact: our nails grow while we’re asleep. So, while you’re in the land of nod why not take the time to protect and nourish them with this dreamy concoction of antioxidant-packed organic white tea, fermented rice, kefir, sake, lily, sweet almond and vitamin E oils. Bedtime is the perfect time to repair, regenerate and hydrate. Yawn.

Containing 76% of naturally sourced ingredients, we meticulously tested this formula during a two-week trial where 80% of users reported regenerated nails and 95% experienced nourished nails and cuticles.

Smells good enough to eat, but please don't.

Oh my LORD - the best!

My nails improved virtually overnight, which sounds crazy, but is magical.

Nails are happy - actually a wonder

My nails are naturally very bendy and peely, but honestly, after a couple of uses - not even on consecutive nights - you can see a difference, even in just the smoothness and clarity of the nail. So happy with such a visible result for my poor nails!!

Love it!

Using this just for a short time and notice a difference, especially with nail ridges.

I’m impressed

So far l have only used the rest and repair. My nails weren’t in very good condition. I’ve been using this for a week now and I have 3 nails left to bring back to good. In particular Ive had a split on my thumb nail for years and in the week lve been using it .. l can still see it because if different colour but the nail is in much better condition and the split is way smaller . I think another week and hopefully my nail will have grown out with no split. My other nails were flaking and they are so much better already. I’m looking forward to trying out the polish once the thumb nail is grown out. I have some colours and a top coat but I want a base coat before I try the polishes. So far though my nails are the best they’ve been for a long time.
