    Hydrating nail and cuticle mask

    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.

    This product is part of our core range. Made in France 14 ml/0.5 fl.oz.

    Why 12-free I hear you ask? The answer is simple. We strip out a lot of bad stuff. While no nail polish can ever be fully free of chemicals, our 12-free brand does not contain formaldehyde, toluene, DBP, camphor, formaldehyde resin, xylene, parabens, fragrances, phthalates, animal ingredients, ethyl tosylamide or triphenyl phosphate.

    To repair dry & flaking nails: Massage the mask into your nails and cuticles. Leave overnight, to repair while you rest. Rinse off with warm water when you wake up, and use our Self Love Oil for extra hydration and TLC. Repeat for 2 weeks or until your nails appear smooth and uniform again.

    For healthy nails and everyday maintenance: Massage the mask into your nails and cuticles. Leave overnight, to repair while you rest. Rinse off with warm water when you wake up, and use with our Miracle Treatment Base Coat for continual repair - even while wearing your favourite polish. Make sure you remove all nail polish and base coats before reapplying our Rest & Repair Mask, as our mask will only nourish bare nails.

    Wish I took a before photo

    I have fallen in love with this product. I think I have only used this for roughly 1 1/2 weeks and I can see it already working. I have had peeling dry nails, that won't grow for years. This seems to have stopped them peeling and look strong and healthy. Would buy again and highly recommend.

    Love Kester Black So Much!!!

    A really nice mask that i would massage into my cuticles on the night when I removed my existing nail colour. The next day after washing my hands, I would apply 2 coats of Miracle base coat. I love this mask as well as the Miracle Base Coat. Thanks Kester Black. xo

    Great product

    I had my doubts about this product, but was desperate to try something to sort my peeling nails. When I initially tried this, I didn't have much luck, however I tried cutting my nails back completely and trying again. This time my nails grew out strong and free of any splits or peeling. It has become a standard part of my nightly routine now!

    Within a week of using the Wonder mask,my nails had grown more and broken less. I've used lots of products in the past to try and get my nails looking good and this has got to be THE BEST!

    The rejuvenation begins

    I'm only one week in and I ahem to say I'm already impressed. From the very first application my nails took on an immediate appearance of hydration. As a long term user of gel tips and shellac my nails are in serious need of a wellness overhaul and it starts here.
