The lamp that cures gel polish emits UVA light. Laboratory studies on cells have shown that UVA from nail lamps can damage DNA in those cells, and nail lamps have not been proven to cause skin cancer in people. Both halves of that sentence are true at once, and you deserve to hear them together. If the exposure bothers you, dermatologists commonly suggest broad-spectrum SPF 30 or higher on your hands before the appointment, or fingerless UV-protective gloves worn during curing. If you would rather skip the lamp altogether, a regular-polish manicure never goes near one.
Ask a search engine whether gel lamps are bad for your skin and you will find two camps. Salon blogs wave the question off in a sentence. Alarmed wellness posts read like a reason to cancel everything. Neither camp trusts you with the middle, which is where this question genuinely lives. Below: what the lamp does, what researchers have found, what remains unproven, and two cheap mitigations that take the worry off the table. Then you decide.
What the Lamp Is Actually Doing
Gel polish cures rather than air-drying. The lamp floods the wet gel with light, the gel hardens in response, and the light doing that work is UVA, a form of ultraviolet. Curing is the entire reason gel behaves the way it does on a nail, and it is also the reason your hands spend time under the lamp while it happens.
That trade is why gel has the following it has. A cured coat shrugs off things that end a regular polish job early. It is not invincible, though; when a set quits ahead of schedule, our post on why gel polish chips walks through the usual culprits.
What Is Known, and What Is Not
Here is the honest state of the evidence. Laboratory studies on cells have shown that UVA from nail lamps can damage DNA in those cells. Nail lamps have not been proven to cause skin cancer in people. Read that pair again, because most articles quote one half and bury the other.
Cell studies matter — they are how researchers flag a mechanism worth watching, and DNA damage in a lab dish is exactly the kind of finding that keeps a question open. What a cell study cannot do is tell you what happens to an actual person over years of manicures. That is the part that remains unproven. Unproven sits between disproven and confirmed, and that is precisely where this question lives today. Anyone who flattens it into "totally safe" or "never again" is doing your thinking for you.
The fix costs less than the manicure: sunscreen before, or fingerless gloves during.
Two Easy Ways to Lower the Exposure
Dermatologists commonly suggest two practical steps, and neither changes a thing about your appointment.
First, sunscreen. Apply a broad-spectrum SPF 30 or higher to your hands before you leave home, the same product you would use on your face. Broad-spectrum is the label that covers UVA, so it is the wording to look for on the bottle.
Second, fingerless UV-protective gloves. They cover the skin of the hand and leave the nails exposed, so the gel cures while your skin sits in shade. Bring a pair to your appointment or ask us about them when you book. Both are welcome at Aloha, and no one will blink.
Pick one or stack both. The point is that the choice stays yours, made with the whole picture in view, and neither option costs you anything in polish, shine, or wear.
If You Would Rather Skip the Lamp
You can, and you will not be giving up the manicure to do it. Every manicure on our menu finishes with regular polish by default, and regular polish needs no lamp. The Tropical is $25, the Paradise Luxe is $35, and the Aloha Glow is $45. Gel is an option at each tier, never an obligation, which means the lamp only enters the picture when you invite it.
Dip powder deserves a mention here, because guests often assume it needs a lamp. The powder itself does not. A gel topcoat over dip does cure under one, so if lamp-free is the goal, say so at booking and the topcoat gets planned around it. For a fuller picture of how the three systems compare, our guide to gel vs dip powder vs acrylic puts them side by side.
Going lamp-free also pairs well with a rebuilding stretch. If your natural nails feel thin or bendy after years of enhancements, our post on nail recovery after acrylics maps out what that looks like, and a regular-polish manicure fits neatly inside the plan.
Why We Answer It This Way
A salon has an obvious incentive to shrug this question off. We would rather put the whole answer on the table and let you pick your manicure with it in view. The team behind Aloha brings two decades of craft from a sister salon, and if that stretch taught one lesson, it is that trust gets built in the unglamorous moments: the sanitation talk, the question answered straight. So a tool gets described by what it does and by what remains unproven. Slogans stay out of it.

The lamp is one of two places UV comes up at a nail appointment. The other is the cabinet our tools are stored in, and what that box can and cannot do is spelled out in how we clean our tools.
Builder gels cure under the same lamps, so if BIAB is on your radar, the same two mitigations apply.
Frequently Asked Questions
Does every gel manicure involve a UV lamp?
Yes. Gel polish cures under lamps that emit UVA, and without the lamp the gel stays wet. Regular polish air-dries and never goes near one.
The lamp at my last salon said LED. Is that still UV?
Gel polish cures under lamps that emit UVA, whatever the label on the machine says. If you are thinking about exposure, treat any lamp that cures gel the same way, and use the same two mitigations.
Should I put sunscreen on before my appointment?
Dermatologists commonly suggest it: a broad-spectrum SPF 30 or higher, applied to your hands before you arrive. The rest of the appointment goes exactly as it would have.
Can I bring my own UV gloves?
Please do. Fingerless UV-protective gloves cover the skin and leave the nail free to cure, and they are welcome at Aloha. If you do not own a pair, ask us about it when you book.
Which manicures skip the lamp entirely?
All of them, unless you choose gel. The Tropical ($25), Paradise Luxe ($35), and Aloha Glow ($45) each finish with regular polish by default, and regular polish needs no lamp.
Does dip powder need a lamp?
The dip powder itself does not. A gel topcoat over dip does cure under a lamp, so tell us at booking if you want the set fully lamp-free and we will plan the topcoat around it.
