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.

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.

Great product

I had always had acrylic or SNS & when Covid hit, like most people had it removed. My nails were in a shocking condition & like paper. This product had helped strengthen my nails & made them look so much healthier. I'm not ashamed to show my hands anymore.

Rest & Repair Wonder Mask

Excellent product - it is making a difference!! I have recently taken off artificial nails, the good old SNS! To say may nails were a mess is an understatement.... I have only been using my new products for a few weeks, having bought a whole new Kester range to give them the TLC they need and restore them to a normal, natural state (I am an older customer) and they are already unrecognisable! :D

Way Better Than Expected

I expected it to be a nice 'treatment' type addition to my nail routine. This is definitely a staple now. It has more of an effect than I expected it to. It also dries a little somewhat like a nail polish even though it's a treatment.
