GRAND RAPIDS, Mich. — Ranir LLC has launched the Rembrandt 1 Week Whitening Kit, formulated to provide faster results for consumers looking to whiten their teeth.

The 1 Week Whitening Kit contains custom-fit teeth whitening strips good for 14 days of whitening treatment, with teeth becoming visibly whiter in half the time, according to Ranir. The company said consumers can see 90% more stain removal than brushing alone in just one week.

Rembrandt whitening kits are made with the same enamel-safe ingredients used by dentists to remove deep stains, Ranir added.

Carrying a suggested retail price of $24.99, the Rembrandt 1 Week Whitening Kit is available at nearly 4,500 Walgreens, Walmart and Target stores nationwide. Consumers can find the 1 Week Whitening Kit in stores using the new product locator on the Rembrandt website.

Ranir said consumers can achieve greater results from the kit when using it with a Rembrandt whitening toothpaste — also available at Walgreens, Walmart and Target stores — and power whitening toothbrushes.

“Rembrandt is the original at-home teeth whitening brand, and we continue to innovate and bring scientifically proven products to the market so consumers can achieve their best smiles right from the comfort of their own home,” stated Don Cumming, global brand director for Rembrandt. “The 1 Week Whitening Kit is the perfect tool to add to your dental care routine, especially when you’re preparing your smile to look its best for your most important moments. And now it’s easy to find on-shelf at some of the nation’s largest retailers with the new product locator on Rembrandt.com.”
