Kiara Sky nail lacquer is a quick-dry, air-dry polish in 15 mL (0.5 fl oz) bottles, made in the USA and free of formaldehyde, toluene and DBP. It needs no lamp, so it suits quick colour changes, pedicures and retail. Each shade is listed by number and name, such as 493 The Real Teal or 611 Un Bare Able, so you can reorder the exact bottle a client chose.
Apply a base coat first, then the lacquer: most shades reach full opacity on the second coat over the base. Finish with a top coat for shine and wear. Let each coat dry before the next, and keep the coats thin so they dry evenly. Lacquer comes off with ordinary nail polish remover, with no soaking or filing needed.
Kiara Sky also sells All-In-One duos, which pair a gel polish with the matching air-dry lacquer in the same shade, and the HEMA-free Gel Pro gel line, listed on their own pages. This page holds the single lacquer bottles. If a client wants her gel and her lacquer to match, check the duo listings first, and compare the bottles side by side before you promise an exact match.
Start with the shades your clients ask for every week: a few nudes, a sheer pink, a true red, a white and a black, then add seasonal colours and brights as bookings change. Because every listing shows the shade number, you can reorder one bottle at a time. Check each listing for stock before planning a display around a particular colour.
Those are two different claims. Kiara Sky describes its Gel Pro gel line as HEMA-free and TPO-free, and Gel Pro has its own page sorted by colour family. The nail lacquer on this page is described as free of formaldehyde, toluene and DBP, which is a lacquer claim, so do not describe the lacquer as HEMA-free unless the label says so.
