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

Please note we have temporarily paused EU shipping as we changeover our fulfilment setup. We expect to be back up and running by the end of February.

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.

All Kester Black products are cruelty-free, vegan and carbon neutral. We’re also a Certified B Corp!

Made in France.

  • 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.

Seems to work

I bought this because my nails kept breaking, I used it for a few weeks and then followed up using the miracle treatment base coat and it has done the trick. Longer and stronger nails! I can’t say how this performs all on its own, but I think it helps.

Great for super dry cuticles

I use this every night before bed. This has helped me so much with my dry cuticles especially with the combination of constantly using hand sanitizers and in general with my eczema.

Amazing

Buy it. Just buy it. Seriously. It’s that good. Hand sanitizer has shredded my hands and nails and this has worked absolute wonders.

Loving it

Having always had soft nails, I am really loving what feels like a strengthening of my nails. They also seem to be whiter.

Wow this stuff works ..

My nails were in bad condition .. bad gel and over use of washing and hand sanitizers . But started using this product 2 weeks ago and I can see the difference already . Chipping stopped and nail looks so much healthier .. will be able to wear the Kester Black babe Colour very soon .
