DND HEMA & TPO Free Gel Duo 142 Lethal Obsidian

DND 142 Lethal Obsidian is a muted plum brown from DND”s HEMA & TPO Free line. You get the gel polish and its matching lacquer, so a gel manicure and a lacquer pedicure come out the same colour.

What you get

1 x DND 142 Lethal Obsidian gel polish, 0.5 fl oz (15 mL), cured under an LED or UV lamp

1 x DND 142 Lethal Obsidian nail lacquer, 0.5 fl oz (15 mL), air-dries

Why techs stock it

TPO free: TPO is the photoinitiator the EU removed from cosmetics in 2025; this formula does not use it.

Rated for 21 days: DND lists up to 21 days of chip-free wear with proper prep.

Does not shrink: DND lists the HEMA & TPO Free formula as non-shrinking and chip-free.

Clean cream finish: no shimmer or glitter, so it reads the same under salon light and daylight.

Which option to choose

Compared with a standard DND duo, DND 142 Lethal Obsidian swaps in a formula without HEMA or TPO while keeping the same gel and lacquer format. It still works with the DND, DC and DIVA base and top gels you already stock.

Storing the bottles

Keep gel bottles closed and away from the lamp and from windows, since stray UV can thicken the gel in the neck. Wipe the neck before capping so the lid does not stick.
