All your questions,
answered.
Straight answers to everything — including the questions other brands avoid.
01 / Choosing & Using Nova
What’s the difference between Nova and Nova Max?
They’re the same device, running the same cold atmospheric plasma technology. The only difference is output — Nova Max generates three times the plasma power of the standard Nova. The 60-Day Skin Trial, lifetime warranty and free shipping are identical for both. If you’re unsure, the standard Nova is the model most customers choose.
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. Orders are processed within 1–2 business days and typically arrive in 7–14 business days (3–7 business days in Australia). Tracking is emailed the moment your order ships.
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.
06 / Orders & Support
What’s in the box?
The complete system: the Nova device, two treatment heads, and the charging cable — in one fitted box. It arrives ready to use.
How do I reach support?
Email info@sub-zero.shop — a human reads every message.
Can I use my HSA or FSA to pay for a Sub-Zero device?
Yes. Every Sub-Zero device is HSA/FSA eligible — we’re partnered with Truemed, who handle the eligibility paperwork, including the Letter of Medical Necessity most plans ask for. Pay with your HSA or FSA card at checkout exactly as you would any other card. If your administrator asks for an itemised receipt, email info@sub-zero.shop and we’ll send one. If you return a device under the 60-Day Skin Trial, the refund goes back to the same HSA/FSA card.
07 / Apex — the 60-Day Trial
Apex — the 60-Day Trial and the $100 gift card
Use Apex for 60 days from the date it is delivered. If you are not satisfied with your result, return the device for a full refund. Opened and used devices are eligible and there is no restocking fee. The device should be returned with the components it shipped with.
Where an Apex trial refund is issued, we also send a $100 gift card of your choice. Two conditions apply: the device must have actually been used across the trial period, and one gift-card claim is permitted per customer.
To start a claim, email info@sub-zero.shop. This clause sits alongside our refund policy, which continues to govern returns.
