DND HEMA & TPO Free Gel Duo 142 Lethal Obsidian
Couldn't load pickup availability
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.

Frequently Asked Questions
Does the lacquer match the gel exactly?+
Yes. DND mixes DND 142 Lethal Obsidian as a gel and a lacquer with the same shade number, so a gel manicure and a lacquer pedicure match. The lacquer air-dries, the gel needs an LED or UV lamp.
What do HEMA free and TPO free mean?+
HEMA is a monomer and the ingredient most linked to allergic reactions from gel polish. TPO is a photoinitiator the EU removed from cosmetics in 2025. This DND line is made without either one.
What colour is Lethal Obsidian?+
DND 142 Lethal Obsidian is a muted plum brown. Screens show colour differently, so check a swatch stick against the client's skin before the full set.
How long do I cure each coat?+
Under an LED lamp, cure each thin colour coat 45 seconds; a UV lamp takes about 2 minutes. Thin coats cure all the way through, thick ones do not.
