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

Please note, we are expecting Supersonic Top Coat to be back in stock by early January. Make sure you sign up to be notified when it's back in stock!

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.
  • Some of our customers require breathable/water-permeable nail polish due to cultural or religious beliefs. For our products to remain breathable, we recommend 3 coats of polish. One Base coat and two coats of colour. Due to this reason, we have decided to discontinue our Breathable Top Coat. If you don’t fall into this category, we recommend the Top Coat or the Supersonic Top Coat for its lightning-fast drying time and super plump, glossy finish.

Applies easily, no strong odours, and super strong! I'll be rebuying this for the rest of my life.

Miracle top coat

This dried so fast and made my manicure last a whole week with no chips. As a notorious no-glove-using dishwasher, this was such a great find for me.

Just be dang sure that your colour has dried enough before applying. I got impatient and put some of this over a less than dry coat (it was still kind of tacky where you could leave impressions on it) and a swipe of the topcoat just took it right off, leaving a bare spot. Other topcoats I've used have been more forgiving of this, but they haven't gone on as smooth or kept my manicure so fresh.

This really works.

For the first time ever nail polish is actually staying on my nails and not chipping off after a day. Love it!
