Whitening Gel Strength Myth

Listen here, or read below

Just because a whitening gel has a higher Hydrogen Peroxide percentage does not make it whiten any better. Hydrogen Peroxide is simply Hydrogen Peroxide, it does NOT have a strength percentage.

So why do Whitening Gels have a percentage like 6 percent, or 12 percent?

Well, it simply means the amount of hydrogen peroxide that has been added BY WEIGHT to the carrier gel.

The Hydrogen Peroxide strength remains EXACTLY the same. Only the WEIGHT of Hydrogen Peroxide within the overall formula changes.

That is why Tooth Bleaching is based upon the gel’s EFFICACY, rather than Hydrogen Peroxide percentage.

EFFICACY is the whitening Gel’s ability to cause the desired effect. Efficacy is a combination based upon SEVEN critical factors:

1. Hydrogen Peroxide by weight within the formula. It has nothing to do with the whitening ‘strength’ (efficacy) of the gel

2. Whether the Whitening gel is catalytically activated. The degree that the Hydrogen Peroxide is photo-excited after mixing with an activation catalyst.

That means an activation catalyst is mixed into the formula via a special mixing tip attached to a dual-barrel syringe. This hyper excites the gel increasing its ability to bleach stains within the tooth enamel.

3. Heat. A slight warmth from the machines light head causes the OSMO gel catalyst to work more effectively with the gel, without any discomfort to the client.

The slight body heat warmth from the device, rather than cold air, reduces over salivation and coughing often associated with old cold blue light machines. Having a natural warmth within the oral cavity helps the client relax.

Both the Beyond Polus Ultra and Beyond II Ultra teeth whitening devices incorporate new High power, warmth producing LED technology, rather than old technology ‘cold blue light’ LED.

4. Strength of the Luminance radiance from the machines light head. Luminance is measured as LUX.

Both the Beyond Polus Ultra and Beyond II Ultra teeth whitening devices produce very high luminance outputs. Up to 300,000 lux.

That is more than twice the SUNS 120,000 luminance at midday in the summer.

Compare the lux output from Beyond machines with old technology LED lights that range between 160,000 to 180,000 lux, and it is easy to see why Beyond machines produce whiter, faster results.

5. The Whitening machines light frequency measured in nanometers.

Between 480-520 nm, that is, just below UV works best with Catalytically activated whitening gels.

7. The time the whitening gel is upon the teeth. Too long can induce sensitivity. Too short and results are less than they could be.

That is why the Australian Cosmetic Teeth Whitening Training Academy course is essential. Ignorance is NOT bliss.

8. Whether it is Ultrasonically stimulated.

Ultrasonically Enhanced machines cause the gel to vibrate at 41,000 cycles per second. This induces the whitening gel to migrate faster into the tooth enamel, rather than soak in.

That means, staining particles deep within the tooth enamel are surrounded more effectively, therefore, producing up to 2 shades whiter teeth in just 36-minutes.

In summary,

The EFFICACY of OSMO catalytically excited 6% whitening gel when used with the Beyond Polus Ultra & Beyond II Ultra whitening accelerator devices, produces results comparable with pure 35% whitening gels that are 580% more caustic

All a higher percentage Hydrogen Peroxide whitening gel does is increase the risk of sensitivity, gum blanching, gum irritation and swollen lips. For example, doubling a 6%HP gel to 12% DOUBLES the risk of sensitivity, Old 35% almost always caused painful sensitivity

In other words, you risk harming your client.

No Professional wants that.


“It’s scary what risks people will take in search of the next great brightening method, especially when research has shown that whitening with a 6% solution is just as effective as using a more powerful formula, without the dangerous side effects”
