All your questions,
answered.
Straight answers to everything — including the questions other brands avoid.
01 / Using Nova
How do I use Nova?
Use Nova on clean, dry skin. Glide it slowly across each treatment area using light pressure — 1–2 minutes per area, 5–8 minutes per session. No gels, no serums underneath, no product required.
How often should I use it?
3–5 sessions per week, depending on your skin concern and treatment protocol. Consistency matters more than intensity — short, regular sessions beat occasional long ones.
Can I use Nova with my existing skincare?
Yes. Nova comes first, on clean, dry skin — then apply your usual products as normal. Nothing in your routine needs to change, and nothing needs to be bought alongside it.
Do I need gels, refills, or cartridges?
No. Nova arrives complete — the device, two treatment heads, and the charging cable in one fitted box. Nothing sold separately, nothing to re-buy.
02 / Safety
Does Nova burn or damage the skin?
No. Nova is non-thermal — the plasma runs at skin temperature. It doesn’t burn, ablate, or create controlled injuries in the skin. It is not a plasma pen; those are heat-based devices from a completely different category.
Is Nova suitable for sensitive, reactive skin?
Nova uses no heat, no chemicals, and no actives — nothing your skin has learned to fear. It was built for reactive, compromised skin.
Is the technology FDA cleared?
Yes — FDA cleared (510(k)), backed by published clinical research on cold atmospheric plasma.
03 / Results
When should I expect to notice a difference?
Skin corrects on a curve, not overnight. Many users notice calmer-looking skin within the first weeks; more consistent change builds over 6–8 weeks of regular use. Results vary by skin concern and severity.
What if I don’t see results?
Start a return within 60 days of delivery — that’s the 60-Day Skin Trial. Opened and used devices are fully eligible when returned with their included components. No restocking fee. See the refund policy.
04 / Guarantee & Warranty
How does the 60-Day Skin Trial work?
Use Nova on your worst skin for a full 60 days. If it isn’t right for your skin, return it for a full refund — even if it has been opened and used, in accordance with our returns policy.
What does the lifetime warranty cover?
If Nova ever develops a manufacturing fault, we repair or replace it. You will never lose your investment to a device failure.
05 / Shipping & Delivery
How long does delivery take?
Shipping is free worldwide, and orders arrive within 7–9 days.
Do you cover customs and duties?
Yes — delivery is free worldwide with customs charges covered. The price you see is the price you pay. Full details on the shipping page.
