The purple part

Why purple beats plain white strips

Most strips just bleach. Ours work with color science to cancel the yellow you can actually see.

Color theory, not bleach overload

Yellow's complement is violet. A purple tone optically neutralizes warm stains the moment it's applied — instant brightness while the active ingredient works underneath.

🛡️

Gentle on enamel

A peroxide-free formula option lifts stains without the zingers and sensitivity that ruin most whitening kits.

30 minutes, once a day

Slim, no-slip strips mold to your teeth. Apply, scroll, peel. Real shade difference by day 7.

Good questions

Before you ask

No. The purple tone is in the gel and neutralizes yellow on contact, then rinses clean. You're left with a brighter, more neutral white — never a purple tint.

Our peroxide-free formula is designed for low sensitivity. If you've reacted to drugstore whitening before, start every other day and build up.

Many people notice an instant brightness from the optical tone, with a real shade lift after the full 7-day course.

Once daily for 30 minutes across 7 days, then top up once a week to maintain. One box = one full 7-day course.

30-day money-back guarantee. If you're not brighter, contact us and we'll refund you — strips finished or not.
