Q & As

Rated 5 out of 5 by 4 reviewers.
Rated 5 out of 5 by Top class product As a base coat fabulous - dries matt so no more guessing about the time needed before applying either colour or topcoat for a perfect manicure. 05 August 2014
Rated 5 out of 5 by Great Product! This product is fab! It really help get nail colours on for longer. 15 July 2014
Rated 5 out of 5 by Love Leighton Denny! I started using Leighton Denny products about a year ago, and don't use any others now. If I use this basecoat followed by two coats of colour and a top coat of crystal finish (and miracle drops to dry it quickly!), I get 5-7 days out of my nails, no chips. For a polish that's not gel with the amount of abuse my hands get, that's great. 27 May 2014
Rated 5 out of 5 by Lovve this product I really love this product. I was introduced to it first when I had a manicure and loved the matt finish. It works well just on its own, but as basecoat it does everything you want it to do, dries quickly, forms an even surface for your colour coat and does not go "gluppy". My only complaint would be that my first bottle must have had a fault in the glass and the top broke off. This was a problem as it was inside a makeup valet case with glass files, hoofs, emery boards, clippers etc all of which had to be thrown away or cleaned with nail varnish remover. 09 November 2011
