Laughland vs PurelyWHITE Deluxe: LED Whitening Kit or Whitening Powder? (2026)

These two land in the same search results for at-home teeth whitening, and they score the same 5.6 out of 10 in our reviews. They are very different products. The Laughland kit is a classic whitening treatment: hydrogen peroxide gel in syringes and a blue LED mouthpiece that plugs into your phone, used for a short session every day for six days. PurelyWHITE Deluxe is a tooth powder you add to your normal brushing, built around PAP, hydroxyapatite and CPC.

So the real choice is between a stronger, shorter course and a gentler daily habit. The scorecard above sums up the rounds. Below is how each round was decided, based on our full reviews, the sellers' pages, independent testing and published dental research. Nobody on our team has used either product.

Which one actually whitens more?

Laughland. Hydrogen peroxide releases oxygen that breaks down stain molecules inside the enamel, so it can lighten the tooth itself, not just its surface. NewMouth's testers measured an average improvement of about 2 VITA shade steps after the six-day course. That is far short of the "7+ shades guaranteed" on Laughland's page, but it is a noticeable lift.

PurelyWHITE's PAP oxidises coloured stain molecules too, and lab studies suggest it does so without softening enamel. But a meta-analysis of non-peroxide whiteners found them less effective than peroxide, with the main effect being surface stain removal. PurelyWHITE also does not disclose how much PAP the powder contains, so it cannot be compared with the formulas tested in studies. Expect brighter teeth if you drink coffee or tea, not a change in your natural shade. Its claim to "permanently whiten 2 to 4 shades in 14 days" is not supported.

Which one is gentler on sensitive teeth?

PurelyWHITE. PAP whitens without producing the free radicals that reach the tooth's nerve, which is why studies and user reports generally find less sensitivity than with hydrogen peroxide. The powder also contains hydroxyapatite, the main mineral in enamel, which has growing evidence for remineralising early weak spots and easing sensitivity.

Laughland is not harsh. Independent testers reported low sensitivity, and the brand sells a peroxide-free formula for sensitive teeth. But its "zero sensitivity" claim comes from a small company trial of 34 people reporting their own results, and peroxide can make some teeth tender. Research also suggests blue whitening lights add little to the effect of peroxide and may increase sensitivity, particularly with stronger gels.

Neither product can promise zero sensitivity for everyone. Stop and see a dentist if either one causes pain.

Which one is easier to fit into your day?

PurelyWHITE. You put a small amount on a damp brush and brush as usual, in addition to your fluoride toothpaste. There are no trays, strips, timers or cables.

Laughland takes more effort but for a shorter time: about 10 to 20 minutes a day for six days, with gel applied from a syringe and the LED mouthpiece powered from your phone. Adapters for USB-C, Lightning and Micro-USB are included. Laughland notes that peroxide breaks down in heat, so do not leave the gel somewhere warm. Its FAQ suggests re-whitening every two to three months, since coffee, tea, red wine and smoking bring stains back.

What does each one cost?

PurelyWHITE costs less per day. Laughland costs less per visible result.

Both pages inflate their discounts with "retail" prices nobody seems to pay, from $99.99 for Laughland's starter kit to $59.99 for a PurelyWHITE jar. Compare the totals instead.

One extra risk sits on Laughland's side: reviewers have reported being added to subscriptions they did not expect. Read every line of the checkout and untick any auto-ship option before paying. Both sellers show a 30-day guarantee; check whether opened products qualify and keep your order confirmation.

Whose claims hold up better?

It is close, which is why the scores match. Laughland's basic promise of gentle at-home whitening is backed by an independent test, but its "7+ shades", "100% success" and "zero sensitivity" claims are not. Its ingredient wording is also muddled: sodium hydroxide is an alkali for adjusting pH, not a gum soother, and "clean, natural" sits awkwardly next to peroxide.

PurelyWHITE's ingredients are real and studied, but the product itself has no published trial, and we found no independent owner ratings. "100% peroxide-free" is misleading because PAP is an organic peroxide. The page also tells two different stories about where PAP came from, and its "1,000,000+ customers" has no source. Laughland edges this round because someone outside the company has tested it.

Which one should you buy?

Buy Laughland if you want your teeth to look noticeably lighter within a week and peroxide does not bother you. It is the stronger product, and the starter kit is a fair price for finding out how your teeth respond. Watch the checkout for subscriptions.

Buy PurelyWHITE if you found peroxide strips too sensitive or your stains come mainly from coffee, tea or wine. It is a reasonable daily add-on and cheap per day, as long as you expect brighter teeth rather than a whiter shade. Keep using fluoride toothpaste either way.

Our verdict

Laughland is the better choice for most people who want whiter teeth, because it wins the round that matters most: actual whitening power, confirmed by an independent test. PurelyWHITE wins on sensitivity, simplicity and cost per day, and it is the right pick for sensitive teeth with surface stains. Both score 5.6 out of 10 for the same reason: real ingredients sold with headline claims their evidence does not support.
