Which option to choose
If a client has reacted to gel before, DND 257 Bad To The Bone is the DND duo to trial, since the line leaves out HEMA and TPO. The base and top gels are separate products, so check their labels too.
Check the shade first
Paint a swatch stick and hold it next to the client's hand before the full set. Screens and lamps both shift how a colour looks.

Frequently Asked Questions
Does the lacquer match the gel exactly?+
Yes. DND mixes DND 257 Bad To The Bone 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 Bad To The Bone?+
DND 257 Bad To The Bone is a blue grey. 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.
