Our purple Teeth Whitening Gel is designed to help reduce everyday tooth discoloration. This special stain-removal formula relies on its unique ingredients and purple color. Because yellow and purple are complementary colors, the purple gel helps neutralize yellowish tones, effectively reducing their appearance while also helping to protect against future yellowing. With regular use, it can help enhance protection against discoloration. Its advanced formula penetrates deeply into the enamel to address persistent stains and brighten teeth. Unlike conventional products, our whitening gel provides an effective solution to take your smile to the next level. Simply apply the gel evenly to the teeth and let it work. The fast results are impressive, leaving you with a radiant smile in no time.

Why do I need the refill gel?
You will need the refill gel once the whitening gel in your kit runs out. It’s always a good idea to purchase a refill set along with your whitening kit to ensure a longer, more consistent whitening treatment.
How does the at-home teeth whitening kit work?
By oxidizing the enamel, discoloration and stains on the teeth are naturally removed, leaving them whiter and brighter.
How can I improve the whitening effect?
Enhance and extend the whitening effect with our activated charcoal. Using it before whitening makes your teeth appear even brighter by removing coarse discoloration beforehand.
How many applications does the gel last for?
Each syringe allows for about 3 to 4 applications. We always recommend purchasing a refill gel together with your whitening kit to maintain long-term treatment.
How long do teeth stay white after application?
The whitening effect usually lasts 1–2 years. Continue good oral hygiene and care after each application.
Is the whitening kit safe?
The DiamondSmile Whitening Kit has been approved, tested, and certified in Germany (CE, FDA, ISO, MSDS). We also recommend visiting your dentist for a professional cleaning and to confirm that your teeth are suitable for at-home whitening treatments.
Is whitening at the dentist better?
Dentists often use hydrogen peroxide or carbamide peroxide as active ingredients, both of which can severely damage enamel and gums and cause pain.
Will the whitening kit work for me?
The active ingredients in our whitening gel are formulated to act directly on the tooth surface, regardless of tooth condition.
Why do we work without peroxides?
Peroxides are highly acidic and can damage teeth, enamel, and gums. They often cause hypersensitivity and irritation, which is why we do not use peroxides in our products.
