Your Whitening Routine

A Visibly Brighter Smile in Three Simple Steps

The TR4 makes professional-level teeth whitening achievable at home. Apply, activate, and let the dual LED technology do the work โ€” just 16 minutes per session is all it takes.

Apply whitening gel to tray
Step 01
Apply the Gel
Apply a thin layer of PAP+ whitening gel evenly to the inner surface of the mouth tray. The peroxide-free formula is gentle on enamel and gum tissue โ€” no pre-treatment preparation needed.
Activate LED whitening session
Step 02
Activate & Relax
Insert the tray, press the touch control to begin, and let the 32 blue and red LEDs work for 16 minutes. The auto-timer alerts you at the end of each session โ€” no guesswork required.
Reveal brighter whiter smile
Step 03
Reveal & Repeat
Remove, rinse and see the difference build with each session. Most users notice visible improvement within the first few uses, with progressively brighter results over consistent treatment.
The Science Behind the Shine

Two Wavelengths. One Brighter Smile.

The TR4 doesn't rely on a single light source. Its 32 LEDs combine two distinct wavelengths โ€” each playing a specific, complementary role in your whitening treatment.

๐Ÿ’™
Blue Light โ€” Whitening Action
High-Brightness Blue LED
High-intensity blue light activates the PAP+ whitening formula, accelerating the chemical process that breaks down surface and sub-surface stains. This is the primary whitening driver โ€” efficient, targeted, and clinically inspired to reduce treatment time while delivering a demonstrably brighter result with each session.
โค๏ธ
Red Light โ€” Comfort & Balance
Red Light Therapy
Red light wavelengths support gum comfort and tissue health during the whitening process, helping to counterbalance the activation energy of the blue light. The combined dual-wavelength approach is what makes the TR4 uniquely suited to users with sensitivity concerns โ€” effective whitening without compromising on comfort.

TR4 PAP+ peroxide-free whitening gel
๐Ÿงช PAP+ Peroxide-Free Formula
Professional Whitening. Zero Peroxide. Zero Compromise.

The TR4 includes three 3ml whitening gel syringes formulated with PAP+ โ€” a modern, science-backed alternative to traditional hydrogen peroxide whitening systems. PAP+ (Phthalimido Peroxy Caproic Acid) oxidises stain molecules directly within the tooth structure, lifting discolouration from coffee, tea, wine and smoking without the enamel erosion or gum sensitivity commonly associated with peroxide-based treatments. The result is visible brightening with each session and a progressively whiter smile that you can maintain comfortably at home.

3 ร— 3ml PAP+ whitening gels included โ€” everything to start immediately
Peroxide-free formula minimises gum irritation and sensitivity
Targets stains from coffee, tea, wine, food and smoking
Progressive brightening with consistent use over treatment period
TR4 wireless rechargeable whitening device
๐Ÿ”‹ Wireless ยท Rechargeable ยท IPX6
Cordless Freedom. Built for Real Life.

The TR4's wireless, rechargeable design eliminates the inconvenience of tethered whitening devices. The 450mAh lithium battery delivers more than ten full 16-minute sessions from a single charge, rechargeable in around 100 minutes via USB magnetic connection. At just 43 grams and measuring 83.5 ร— 66 ร— 26mm, it's compact enough to pack without a second thought. The IPX6 waterproof rating means it handles accidental splashes in the bathroom without concern, and its lightweight ergonomic mouth tray ensures even gel coverage for consistently uniform whitening results.

10+ sessions per charge โ€” no interruptions to your whitening routine
USB magnetic charging โ€” fully recharged in approximately 100 minutes

โฑ๏ธ Auto 16-Minute Smart Timer
Precision Control. Effortless Operation.

The TR4's touch control interface makes operation completely intuitive. A sensitive touch-and-long-press system activates your session instantly, while the automatic 16-minute cycle handles the timing so you can multitask freely โ€” read, watch, relax. Buzzer alerts notify you at session start, completion, and when the battery is running low, so you're never caught off guard. The uniform tray design ensures full coverage across all visible teeth, delivering balanced whitening results without patchy inconsistency.

Everything You Need to Know

The Trendlox TR4 Rechargeable LED Teeth Whitening Kit is a complete, professional-inspired whitening system designed for effective, sensitivity-free use at home. At its core is a 32-LED dual-wavelength light engine combining high-brightness blue LEDs โ€” which activate the PAP+ whitening formula to break down surface and sub-surface staining โ€” with red LEDs that support gum comfort and tissue balance during each session. This dual-light approach is what distinguishes the TR4 from single-wavelength devices and makes it particularly well-suited to those who have previously found whitening treatments uncomfortable.

The included PAP+ whitening formula is peroxide-free, representing the modern professional standard for sensitivity-conscious whitening. Three 3ml gel syringes are included in the kit, providing everything needed to begin a full course of treatment immediately. PAP+ (Phthalimido Peroxy Caproic Acid) targets discolouration from coffee, tea, wine, food and smoking without the enamel-weakening or gum irritation associated with traditional hydrogen peroxide systems โ€” producing progressive, visible results with consistent use.

The TR4's wireless, rechargeable design features a 450mAh lithium battery delivering more than ten 16-minute sessions per charge, with USB magnetic charging completing in approximately 100 minutes. Its touch control interface with automatic session timer and buzzer alerts makes operation effortless. Weighing just 43 grams with an IPX6 waterproof rating, it is as practical for daily home use as it is for travel.

Noticeably whiter in less than a week
"I've tried whitening strips, charcoal toothpaste, all of it. Nothing has come close to the TR4. After just four sessions I could see a clear difference in photos. My teeth look genuinely whiter without feeling sensitive at all. The fact it's wireless makes it so easy to use while watching TV. I was not expecting results this good at this price."

Finally a whitening kit that doesn't hurt
"I have really sensitive teeth and gave up on whitening years ago because the pain wasn't worth it. A friend recommended the TR4 and I was sceptical but the difference is remarkable. I've done twelve sessions now with zero sensitivity whatsoever. My teeth are visibly several shades lighter and my confidence when I smile has genuinely improved. Cannot recommend highly enough."

Packed this for my holiday and it was perfect
"The TR4 came with me on a two-week holiday and I used it every other day. The battery lasted the entire trip without needing to charge, and it took up almost no space in my toiletry bag. I came back with a noticeably brighter smile and several people asked if I'd had my teeth done. Three syringes in the kit gives you plenty to get through a proper treatment course too."
