Furthermore, it is also made of premium-quality material. Review: High-strength. To be used to obtain rapid results, and for those who need whitening more than a few levels. Many other brands on desertcart do not specify what strength their carbamide peroxide whitening gel is. That's a red flag in my opinion. The weaker the gel, the more you must use in order to get the desired results (especially if, as I said, you have deeper staining). I saw noticeable results after 1 use, and even more of a stark, positive difference after the 2nd application. For best results, apply the gel after brushing your teeth, and gently drying your teeth with a tissue, cotton ball, or cotton swabs. Then, apply the gel in a moderately-thick layer on each tooth. Be sure to apply some to any crevices between your teeth. You can also apply it to the biting/chewing surfaces of your teeth near the front (canines and molars) if you desire whitening there. Then, use your mouth guard, or mouth guard and attached LED blue light (I used a mouth guard with LED blue light I had from another kit). That other kit I purchased from desertcart (a different brand/company from this one) was great. The exception is that the carbamide peroxide was weak, and I would end up taking a long time to whiten my teeth (weeks instead of days). Plus, when makers do that (produce a weak gel), they cause consumers to buy more of it to get the whitening level they seek. It's a waste of money. I suggest buying a STRONG gel to begin with of 22% or 35% carbamide peroxide to start, and if you have no sensitivity issues, continue to use that, and use whenever you need a touch-up. I went to 44% after using 22% and 35% over the years (as well as having tried Crest White Strips, professional whitening strips, and over-the-counter (in store) whitening pens). I highly recommend this gel. Only use it if you have no problems with sensitivity, burning, soreness, allergies, and/or adverse reactions with your gums, lips, or inner buccal cavity (inside of the cheeks). I have not had any problems with that so far. My teeth look and feel great after using this! I am a black tea drinker (and occasionally, coffee and red wine). I also use lots of potent spices that can stain teeth (and also fabrics) in my cooking and daily meals (like turmeric, chili powder, cayenne powder, cumin, mace, paprika, Etc). This gel will be my go-to from now on as long as they continue to sell it! The price point is very, very good. There are much weaker strengths of whitening gels in the desertcart market that cost considerably more. The fast and significant whitening that this gel by Zero Glow offers gives a person more bang for their buck. ★ NOTE: Please remember to store your unused peroxide gel in the refrigerator to prevent degradation and weakening due to ambient temperature changes in your home or office. It is not advisable to freeze it from what I have read over the years. ★ Disclaimer: This is a review that is *WITHOUT* any coaxing, promotional incentives, affiliate discounts, business contracts, social media influencer advertising, requests by the company to leave a review, and commissions. I am a regular desertcart Prime customer who shops often due to the deals I find on desertcart as compared to in [brick and mortar] stores. I do not leave reviews on items often, but I felt this product deserved a great review due to others rating it lower than I feel it should be. Zero Glow deserves at least a 4-star rating minimum, and I'm very happy with their product. Review: Great product and great price. Easy to use and they seem to do the job at whitening your teeth. It comes with a lot of product in each individual syringe. I've tried more expensive brands that provide less product, but these seem to work great. ## Features - Brand: Zero - Type: Tooth Whitener - Teeth whitening kit refill made fresh in the USA - Unique design ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07TYTYJDJ | | ASIN | B07TYTYJDJ | | Active Ingredients | Carbamide Peroxide | | Age Range Description | Adult | | Best Sellers Rank | #79,370 in Health ( See Top 100 in Health ) #61 in Teeth Whitening Gels | | Brand Name | Zero Glow | | Customer Reviews | 4.2 4.2 out of 5 stars (3,196) | | Customer reviews | 4.2 4.2 out of 5 stars (3,196) | | Flavor | Unflavored | | Included Components | Teeth Whitening Gel | | Item Form | Gel | | Item Weight | 0.07 Kilograms | | Item model number | f-85 | | Manufacturer | Zero Glow | | Manufacturer | Zero Glow | | Manufacturer Part Number | TWRZ | | Material Type Free | Artificial Flavor Free | | Model Number | f-85 | | Number of Items | 1 | | Package Dimensions | 17.2 x 10.59 x 4.09 cm; 68 g | | Product Benefits | Whitening | | Set Name | 1 | | UPC | 816932029787 | | Unit Count | 31 Grams | ## Product Details - **Active Ingredients:** Carbamide Peroxide - **Brand:** Zero Glow - **Item form:** Gel - **Number of Items:** 1 - **Product benefits:** Whitening ## Images ![Teeth Whitening Gel Refill - 4x Syringes 44% Carbamide Peroxide - Image 1](https://m.media-amazon.com/images/I/61QgWG67dgL.jpg) ## Questions & Answers **Q: Cruelty-free?** A: I did not experience any cruelty. **Q: How much should i put?** A: You doNOT need half the syringe.

Easy to use and they seem to do the job at whitening your teeth. It comes with a lot of product in each individual syringe. I've tried more expensive brands that provide less product, but these seem to work great. ### ⭐⭐⭐⭐ Review *by N***D on 22 October 2019* I bought this 44% carbamide peroxide gel to replace a 35% product that was not working for me, possibly because it was stored too long. So far, I have used it for 4 days in a row - for 30 minute intervals - and I see a slight shade difference in just those few treatments. Others have complained about the syringe opening being too big/contents coming out too fast, but I think it may be necessary given the fact that the gel is thicker than most. This makes it easy to spread on my teeth without dripping, but it does require being careful when depressing the syringe. Best of all, there is NO irritation to my teeth which tend to be sensitive. I will continue to use it daily and see whether the whitening effect continues. My guess is it will, but am giving it four stars out five just in case it isn't that effective. ## Frequently Bought Together - Zero Glow Teeth Whitening Gel Refill 4X Syringes 44% Carbamide Peroxide - Zero Glow Teeth Whitening Kit Carbamide Peroxide Syringes, LED Light --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/257208118-teeth-whitening-gel-refill-4x-syringes-44-carbamide-peroxide](https://www.desertcart.us/products/257208118-teeth-whitening-gel-refill-4x-syringes-44-carbamide-peroxide) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-18*
