  • How white will my teeth get?
    Individual results vary, depending on your genetics, what type of stain you have (yellow=easiest to remove, brown=somewhat more difficult to remove, gray=difficult may require a series of treatments), and how thick your enamel is. We typically see 2 – 14 shades improvement in the first session: then 1-3 shades using the take home whitening pen.
  • How long do the results last?
    Individual results vary, depending on your tendency to absorb stains, your diet (coffee, tea, red wine, sodas, etc.) and lifestyle (tobacco products). Results can last up to 2 years, with proper maintenance: using the Whitening Pen, avoiding staining products, avoiding enamel-stripping substances (drugstore white strips, sugar, sodas), avoiding drugstore whitening toothpastes that contain silica or other abrasive ingredients which scratch enamel. 2-4 sessions are recommended to prevent relapse. Relapse is when bleached teeth revert to their original stained color. Getting 2-4 sessions greatly helps prevent relapse. If your salon or spa decides to incorporate teeth whitening into your line of services, you can offer follow-up sessions right at your location. If not, we recommend clients use the Whitening Pen so they can perform their follow ups at home. They are meant for maintenance, to remove daily stains but not for tougher, deeper stains from years of accumulation. Therefore, they are only 30% as effective as in-office treatments in the presence of the whitening accelerator light.)
  • Who manufactures your products?
    Our specially formulated gel products are made fresh in the USA. We keep a very stringent control policy on our products to ensure that we are always providing a consistent product with at least a 2 year shelf life.
  • Is It Safe?
    Yes. This is an FDA-registered procedure. Our product does not cause sensitivity; we do not use citric acid, silica, or any other damaging agent to the enamel. When teeth are normal and healthy there are no adverse side effects to the tooth’s enamel.
  • How often can I get my teeth whitened?
    The Whitening treatment can be done 2-4 times per year and does not deteriorate the enamel. Check with your Dentist regarding your specific situation and questions.
  • Does teeth whitening work for everyone?
    Teeth Whitening is not as effective for individuals with intrinsic staining to the teeth. These are the results of certain medications, decalcification, or those who were born with grayish teeth. It is not recommended for pregnant or nursing women or children under 18. Unless written permission from an adult.
  • Will teeth whitening affect dental work?
    The whitening process will only whiten veneers and crowns back to their original color. The process does not adversely affect these structures or fillings.
  • Are there any side effects?
    A small percentage of clients will experience some slight tingling sensation during the treatment. Occasional blanching can occur which is just a temporary whitening of areas around the teeth. This goes away within a few hours.
  • Does the gel cause sensitivity?
    Our specially formulated gel is pH balanced and does not contain citric acid or silica which are commonly found in many over-the-counter whitening strips, known for causing sensitivity. NUYU Whitening was engineered to be an effective, affordable, and pain-free treatment. Our process does NOT require uncomfortable prep time, the use of gingival barriers, or cheek retractors.
  • How much space is required?
    4’ x 4’ space is all that is required with an electrical outlet for the light. You can use any chair as the system is completely mobile and easy to store.
  • How much does it cost to re-order product?
    Being that our prices are only shared with our approved wholesale account partners we keep them hidden until we verify that you qualify to purchase our products.
  • What are the ingredients of the teeth whitening gel?
    Our pre-filled trays contain a carbamide peroxide/hydrogen peroxide hybrid formula that is perfectly balanced and does not damage the tooth enamel. Whitening Pens contain Hydrogen Peroxide. We have a numbing agent in our gel that helps to reduce sensitivity.
  • Is there a warranty on the light?
    There is a 1-year manufacturer’s warrantyon the Cool Blue LED light and a lifetime warranty honored from Renew You if the client orders at least 10 kits per month.
  • How long does shipping take?
    We ship within 1-2 days once we receive your order. Allow 5-7 business days for delivery within the US and Canada.
