Maybe your mornings revolve around coffee. Or perhaps a glass of red wine is your nightly go-to. Whether it’s habits, genetics, or age, most of us will find that our smiles start to look a little dull over time. That’s why at-home teeth whitening kits are so popular.
Luelli is a popular whitening option. This LED-enhanced whitening kit claims to produce visible changes in a single session, with full results taking 7–10 days. And unlike many LED kits, you can purchase it for less than $40. But does Luelli deliver on its promises? We investigated and assembled everything you need to know about the Luelli Teeth Whitening Kit.

Luelli Teeth Whitening Kit at a Glance
Luelli first launched in 2020, aiming to fill the gaps in the oral care market. They saw that some affordable products didn’t get the job done, and some effective products were too expensive. Their goal was to create quality oral care solutions sold at affordable prices. As Luelli states: “We revolutionize products that really work better than anything else with reasonable prices compared to other brands.”
At the moment, they offer two complete teeth whitening kits, both with LED lights. They also sell their whitening gel on its own, which can work as a refill for their kits or on its own.
According to the company, you will see noticeable results after a single 10-minute session, and finish treatment in as little as seven days (if used once each day), or up to 14. If you use the lights, a built-in timer ensures you won’t over-whiten and damage your teeth.
You can purchase Luelli whitening kits directly from the company’s website or order them through third-party sites like Amazon. We suggest shopping around to get the best deal.
Pros & Cons of Luelli Teeth Whitening Kit
Luelli’s whitening kits are high-quality and effective, but no option is 100% perfect. Here are the biggest pros and cons of choosing Luelli.
Pros of Luelli Teeth Whitening Kit
- Each session with their standard kit is just ten minutes long. If you choose their premium option, this increases to 16.
- The Luelli whitening kit is one of the most affordable LED-enhanced options on the market, and you can often get it for lower than the list price.
- You can reuse the light for years to come, reducing the cost of whitening your teeth in the future.
Cons of Luelli Teeth Whitening Kit
- Some customers said that the gel will burn if it gets on your gums.
- Other customers complained that the one-size-fits-all trays are too big for their mouths.
Are Luelli Whitening Trays Right for You?
We think they’re a solid option for anyone who wants a convenient LED whitening kit, but doesn’t want to drop a ton of money. However, if you need more info, read on — or check out our picks for the best at-home whitening kits.
If a product can’t actually brighten your smile, things like price and comfort don’t really matter. Based on both company claims and customer reviews, Luelli seems to be pretty effective.
Luelli states that you’ll see initial results after a single ten-minute whitening session. You can whiten once per day for up to 14 days in a row (although the kit only has enough gel for nine uses), but the company says that most people need only 7–10. Most customer reviews seem to back these claims. Many people noticed a difference after their first application and wrapped up in seven days.
Since Luelli is a tray-based whitening system, it is more effective than options like pens, as it holds the gel in place against the teeth. And unlike strips, the tray will not slip out of place. Luelli’s gel uses 35% carbamide peroxide, which is less potent than hydrogen peroxide, but still effective.
Like nearly all whitening treatments — at-home or professional — Luelli works best on yellow stains. Brown, black, and purple stains rarely change much, if at all. Results last 6–12 months, depending on your habits. Luelli suggests you complete maintenance treatments about every 2–5 months and a full round of whitening every 6–9 months.
You can choose from two different LED lights. Luelli’s standard kit mouthpiece features 5 LED lights that strictly produce blue light, while their premium kit’s mouthpiece has 32 LED lights that can change modes to blue, red, or both, depending on if you want to whiten, sanitize, or both.
Do LEDs for Whitening Work?
LEDs are popular for teeth whitening right now, and while the kits work well, the research is mixed on how much the LED improves their effectiveness. This 2014 study found that they didn’t improve whitening results much, while this 2021 study showed that blue light “enhances both the bleaching rate and the final whiteness level.”
Either way, it’s considered safe, so if you like the idea of using an LED with your whitening products, go for it.
Professional whitening can deliver significant changes to your smile in a single session. You walk into the office, then walk out about 1–2 hours later with a megawatt grin. But most people still choose to whiten at home — even if it takes longer to see results — because it’s cheaper.
Professional whitening is typically at least $400 per session and, depending on the system and dentist, could cost you over $1,000. Luelli won’t match in-office speed or power, but many people think the savings are worth it.
However, Luelli isn’t just priced lower than professional treatments; it’s more affordable than most other LED kits. Where some options cost roughly $200, Luelli’s standard kit is $39.99 and their premium option is $59.99. Usually, the company offers $10–$20 off this price when you purchase through their site, and you can get a discount code for your first order if you subscribe to their email list.
A good way to evaluate the value of a whitening system is to see how the cost breaks down per session. Luelli says their kits come with enough gel for nine whitening sessions. This means their standard kit costs $4.44 per session while their premium option is $6.66 per session. And since the lights are reusable and the company sells gel refill kits, you can reduce your costs over time. Their refill kits are $16.99 for nine treatments, or $1.88 per whitening session.
Quality of Ingredients
Effectiveness and affordability are important, but this is your smile we’re talking about — you need to know that your teeth will be safe, too. The core ingredient in Luelli’s whitening gel is carbamide peroxide. It works by oxidizing stain molecules and breaking them down, which both makes them less visible and allows them to be lifted out of the enamel.
Carbamide peroxide contains hydrogen peroxide but at a low concentration. For every 10% of carbamide peroxide, there is 3% hydrogen peroxide, making it a gentler whitening agent. The version they use has a 35% concentration, which has still proven effective for whitening.
Besides this active whitening agent, the Luelli’s formula contains:
- Carbopol: A polymer that thickens the gel, so it isn’t too watery.
- Propanediol: This helps keep the gel in liquid form and dissolves the other ingredients.
- Glycerine: This pulls moisture from the enamel, making it easier for the peroxide to work.
All these ingredients are common in oral care and beauty products. They are considered safe for humans when used properly.
Whitening your smile comes with plenty of benefits — it can boost your confidence and even improve your mood. However, it can also complicate your schedule. You need to make time to complete your treatments, and even the easiest system will involve some prep and cleanup.
Luelli requires a small amount of prep; you’ll squirt the gel into the tray before placing it on your teeth. It’s not too hard, though it might take time to get the amount and placement perfect. Don’t be afraid to watch some video tutorials to master your technique. Cleanup just requires you to detach the tray, rinse it, and then put everything away.
Each standard Luelli whitening session is ten minutes (or you can use the premium kit for up to 16 minutes at a time). Because the light is battery-operated, you are free to do other things while wearing it — like cleaning the house, doing your morning routine, or even working. In total, Luelli should take about 15 minutes from prep to cleanup.
Because it uses trays and a light, it’s not as portable or inconspicuous as whitening strips or whitening pens. And since you have to prep the trays yourself, it’s not as easy as pre-filled trays. That means it’s difficult to take on the go, but since the sessions are short, that’s not a huge deal.
Here’s an often-unstated truth: whitening your teeth is awkward. From weird flavors to bulky trays to cheek stretchers, there’s a lot that can make you uncomfortable. Fortunately, on the whole, Luelli is pretty comfortable to use.
They include a desensitizing gel in each of their kits and their refills. If you have sensitive teeth or start to develop zingers during treatment, you’ll just place this gel on your teeth after each whitening session. Use the tray to help it stay in place for 15–20 minutes so you can enjoy its full effects.
Since the gel is peroxide-based, it might have a slight chemical-like flavor. However, the tray should stop you from tasting it unless you apply too much. Plus, the gel has a slightly minty flavor, according to customers. There’s no mint-flavored ingredient listed on their website, but we’ll take buyers’ words for it. Some customers say this gel burns if you get it on your gums, so be careful when filling and applying your trays.
Some people also say it’s bulky, especially if you have a small mouth. When the light is attached, it can start to feel a little strenuous by the end of the whitening session. Still, most people find it bearable, and certainly not a deal breaker.
What Are Luelli Customers Saying?
Overall, the Luelli customer reviews we came across were positive, stating they saw results quickly, found the process easy, and appreciated the low price point. However, there were some complaints related to light malfunctions, gum irritation, and tray discomfort. Most customers were pleased with their results, but a few said the whitening didn’t meet their expectations.
Of course, you don’t need to take our word for it. Check out some customer testimonials below.
The Luelli LED whitening kit is effective at addressing yellow tooth stains in most individuals, using gentle ingredients paired with a desensitizing gel for comfort. If you choose either of their LED kits, we think you’ll be happy with your experience. Just remember that, like all at-home kits, there are certain types of stains it can’t change and the results aren’t as robust as in-office whitening.

Frequently Asked Questions
Do LED lights actually enhance whitening results?
The research is mixed, but some studies indicate that LED lights can improve whitening results. While LEDs tend to be the least effective at improving teeth whitening, they might still make a difference. And although other lights can be more effective, they are not considered safe for at-home use.
Does the LED mouthpiece get warm?
LED lights are low heat — but not no heat. The amount of heat they give off is so low that you likely won’t notice it even if you choose the 32 LED light kit. Interestingly enough, heat might help intensify whitening results, but GLO Brilliant is the only at-home kit we have found using it.
Is at-home teeth whitening actually safe?
At-home kits have been in use for decades and millions of people use them every year. As long as you consult your dentist first, and your teeth and gums are healthy, you should be safe to use Luelli and other reputable products. Just keep the following caveats in mind:
- Verify that the product you are purchasing is authentic. When buying from third-party sites, sometimes you will encounter false products that might use unsafe ingredients or have unclear instructions.
- Always follow the instructions that come with your kit. If they say you shouldn’t use the gel for more than ten minutes, don’t. The directions should also specify the maximum number of days in a row that you can whiten your teeth and how many weeks or months you should take off after you finish treatment.
- Check the ingredients list if you have any allergies. Not all whitening gels are hypoallergenic and there are a wide variety of ingredients that they might use. Double-check before purchasing and check again when the product arrives, just in case the online description doesn’t match what’s on the packaging.
Should I whiten my teeth before or after my six-month dental cleaning?
Neither is wrong but after is better. Your dentist will remove plaque and tartar buildup from tooth surfaces. If you have tartar when you whiten, your results will be spotty.
I don’t drink coffee, tea, or wine, but my teeth are yellowing. What’s going on?
Coffee, tea, and wine stain the teeth, but so do other things, like berries, soda, and tobacco. Also, teeth dull with age, no matter your habits. This is because the enamel wears down and allows the yellow of the dentin to show through.
If I have a fixed appliance, like braces or a bonded retainer, can I still whiten my teeth?
You can, and it won’t damage your appliance, as long as the tray isn’t too tight. However, you will end up with uneven results after removing it. That’s because the whitening agent can’t reach the places where the appliance is bonded to the teeth.
Is it safe for someone who is pregnant or breastfeeding to whiten their teeth?
There isn’t much research on this. It’s best to talk to an OBGYN or pediatrician before starting treatment to get tailored professional guidance.
Is it possible to whiten caps, crowns, fillings, and veneers?
If you’re talking about surface stains that have built up over the years, yes — but make sure the kit you choose is safe for cosmetic and restorative dentistry. If you dislike the color of the material, though, you won’t see the results you want. Whitening kits cannot brighten dental materials.
Are whitening trays better than strips or pens?
Not always. They can be better at holding the gel in place so it can work, but it really depends on your needs and goals. Focus on finding the product that offers the best fit for you rather than what people say is the best overall.
