Fast-drying high gloss top coat - 14ml / 0.5 fl.oz

Made for those with better things to do than wait for their top coat to dry, this antioxidant-rich formula dries to the touch in 60 seconds. Certified organic passionflower, jojoba oil, Australian-sun-proof UV filters and a hefty dollop of impatience get your fingers moving again. Ready? Set.

Note: Top Coat works best as a top coat only - it’s formulated to bond to nail polish, not your nail, so avoid using as a base coat or a clear polish.

This formula contains 77% of naturally sourced ingredients.

Hero ingredients:

Passionflower - known for its rich levels of vitamin C and antioxidant protection.

UV filters -  The highest UV protection against the harsh Australian sun.

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

Made in France.

  • Once your polish is dry, glide the Top Coat over each fingernail, coating the surface from base to tip. Make sure to ‘cap’ the ends to prevent chipping.
  • Ethyl Acetate, Butyl Acetate, Cellulose Acetate Butyrate, Isopropyl Alcohol, Isosorbide Dicaprylate/Caprate, N-butyl Alcohol, Benzophenone-1, Passiflora Edulis Seed Oil, Acrylates Copolymer, Persea Gratissima (Avocado) Oil (Persea Gratissima Oil)*, Adipic Acid/Neopentyl Glycol/Trimellitic Anhydride Copolymer, Trimethylpentanediyl Dibenzoate, Violet 2 (Ci 60725). *Organic/Bio.
  • We made our Breathable Top Coat for people who require breathable/water-permeable nail polish due to cultural or religious beliefs. If you don’t fall into this category, we recommend the Supersonic Top Coat for its lightning-fast drying time and super plump, glossy finish (as opposed to the satin finish of our Breathable Top Coat).

No wonder it gets sold out so often!

Hands down the best top coat I have ever used. Super easy to apply, dries the polish really fast and stays on for ages. Well done Kester Black!

Only the best

I love KB Products, this is a great top coat. I bought it for my grandmother who loved doing her nails. It helps keep the colour glossy and ensures it stays on for longer.

Best top coat I've used

This is, by far, the best top coat I've ever used.

It just works so well with my nail chemistry (nail polish just loves to peel off my nails within hours normally), it sets quickly and lasts longer than many other good quality ones I've tried (including OPI and ORLY).

I thoroughly recommend trying this if you have problematic nails in polish longevity and similar issues.

Shiny!

This too coat works really well. I reapplied if after two days and it was at least 5 -6 days before my polish chipped but it wasn’t that noticeable.
