Description

Hydrogen peroxide whitens by penetrating enamel and oxidising everything inside stains and structure alike. It works. It is also why whitening causes sensitivity.

PAP is a different mechanism: it breaks down stain molecules at the tooth surface, without the enamel penetration. Comparable result. None of the aftermath. Peroxide-free was not a compromise it was the point.

PAP - the whitening active. No peroxide, no sensitivity cycle, no 48-hour coffee ban
Nano-Hydroxyapatite - supports enamel mineral balance during every 30-minute session
Xylitol - freshens and balances oral pH after treatment
Engineered to stay put - ultra-thin, stretchable, no-slip for the full 30 minutes. They come off clean: no gel residue, no stickiness

42 strips. 21 treatments. Once daily for up to three weeks the day-21 result is not the day-3 result. Consistency is the mechanism, not intensity.

Step V. Applied on a prepared mouth, as intended.

The Method

Brush your teeth before applying the strips. Dry tooth surfaces hold better. Peel the strip from the liner. Apply the upper strip first align with the gumline and press gently across all tooth surfaces. Apply the lower strip the same way. The no-slip adhesion locks both strips in place.
Leave in for 30 minutes. The advanced WPF formula works during that time. Do not eat, drink, or rinse while wearing. After 30 minutes, remove both strips and discard them. Rinse your mouth or brush your teeth.
For visible results: use once daily for 7–21 days. Consistency matters more than intensity with PAP. Results accumulate with regular use.
This is Step Five. It works best when Steps One through Four have been completed tongue scraped, mouth flushed, teeth brushed, oral environment maintained. The strip performs at its best on a clean tooth surface.

PAP, NOT PEROXIDE

Peroxide whitens by penetrating enamel and oxidising everything inside which is why it hurts. PAP breaks down stain molecules at the surface. Comparable result. None of the aftermath.

nHA ON GUARD

Nano-hydroxyapatite the mineral your enamel is made of supports mineral balance during every session, countering surface disruption while the strip works. Whitening and protection in the same strip is the point.

ENGINEERED TO STAY PUT

Ultra-thin, stretchable, no-slip. They conform to curved teeth, hold for the full 30 minutes, and come off clean no gel residue, no stickiness.

21 DAYS. BY DESIGN.

PAP whitening is gradual. The day-21 result is not the day-3 result consistency is the mechanism, not intensity. 42 strips. 21 treatments. Then maintenance.

WHAT EVERYONE ELSE PUTS IN.

Eleven ingredients. Six deliberate absences. The first one is what everybody else uses.

No Peroxide

Every mainstream whitening strip uses hydrogen or carbamide peroxide. It works by driving oxygen through enamel to bleach stains from within, and that migration is what produces the sensitivity, the gum irritation, and the two days of beige food afterward. We use PAP, which oxidizes stain at the surface and goes no further. Same result. No recovery period

No Chlorine Dioxide

Marketed as a natural whitener. It works by etching - lowering the enamel surface until the stain comes away with it. Whiter teeth, and measurably fewer of them.

No Charcoal

Abrasive, unregulated in particle size, and it whitens by sanding. Enamel does not grow back. We would rather remove the stain than the tooth.

No Parabens

Not needed for stability here, so not included.

No Titanium Dioxide

A white pigment. Using one to make teeth appear whiter is a magic trick, not a treatment.

No LED Device

Blue light does not accelerate PAP. Kits that bundle one are selling you a prop and charging you for it. Strips, thirty minutes, no batteries.

Questions. Honest Answers.

Q: Why PAP instead of hydrogen peroxide?

Hydrogen peroxide whitens by penetrating enamel and oxidising stain compounds inside the tooth. It is effective but frequently causes sensitivity and can weaken enamel structure with repeated use. PAP (Phthalimidoperoxycaproic Acid) targets stain chromophores at the tooth surface without the same degree of enamel penetration. The visible whitening result is comparable. The sensitivity side effect is significantly reduced. nHA in the formula also supports enamel mineral balance during the process. Peroxide-free was not a compromise was the point.

Q: What is WPF?

WPF stands for Whitening Performance Formula MasterMedi's formulation designation for this product's combination of PAP, nHA, and Xylitol. It indicates that the formula is designed specifically for whitening performance (PAP) while simultaneously protecting enamel (nHA) and supporting the oral environment (Xylitol). Not a marketing term the three ingredients each do a specific clinical job.

Q: How does nHA help during whitening?

Nano Hydroxyapatite particles are small enough to fill micro-abrasions in the enamel surface. During a whitening session, even gentle whitening can temporarily affect enamel surface integrity. nHA bonds to those micro-abrasions, replenishing mineral structure and reducing the pathway for sensitivity signals. It also contributes to surface smoothness, which improves light reflection a whiter-looking tooth is partly a smoother tooth.

Q: How long until I see results?

PAP whitening is gradual it lifts surface stains progressively with each session rather than in one aggressive treatment. Most users see noticeable improvement within 7 days of daily use. Full treatment over 21 days produces more significant results. This is intentional: gradual whitening is gentler on enamel and more sustainable than a single high-intensity session.

Q: Can I use these if I have sensitive teeth?

Yes. The peroxide-free formula means the primary cause of whitening-induced sensitivity is removed. nHA in the formula actively supports enamel mineral balance during the session, which further reduces sensitivity pathways. If you have existing dentinal hypersensitivity or have recently had dental work, consult your dentist before starting a whitening treatment but the formulation is designed with sensitivity in mind.

Q: How is this different from the Clean Mint Toothpaste?

The toothpaste is a daily maintenance product its PAP is formulated for brushing contact time and works alongside nHA, Xylitol, and Probiotic for daily oral care. The strips are a targeted whitening treatment a 30-minute daily session with a higher-contact PAP delivery directly on the tooth surface. The toothpaste maintains. The strips whiten. Both use PAP and nHA, but the delivery mechanism and treatment intensity are different. Using both is the complete approach.

Q: How many treatments do I get per box?

The 42-strip box contains 21 treatments one upper strip and one lower strip per treatment, used daily. The 14-strip box contains 7 treatments. One treatment = 30 minutes = one upper and one lower strip. Both sizes contain the same formula at the same concentration.

Q: Do I need to brush first?

Yes. Apply to dry, brushed teeth for best adhesion and best results. A clean tooth surface with no toothpaste film allows the no-slip adhesive to grip properly and allows PAP direct contact with the stained enamel surface. Brush, rinse, dry slightly, then apply. Do not apply to wet or saliva-coated teeth.

Q: Can I eat or drink while wearing the strips?

No. The strips are a closed-mouth treatment. Eating or drinking during the 30 minutes disrupts adhesion and dilutes the formula. Water is also not recommended during wear it can compromise the no-slip grip. Remove strips after 30 minutes, then eat and drink normally.

Q: How often can I use these? Is daily use safe?

Daily use for 7–21 days is the recommended treatment cycle. After the treatment period, maintenance use 2–3 times per week is appropriate. The peroxide-free formula and nHA enamel support make this suitable for daily use without the enamel depletion risks associated with daily peroxide-based whitening.

Q: This is Step Five. What are the steps before it?

Step One: UV Smart Flosser -cremoves debris between teeth and below the gumline. Step Two: Tongue Scraper -cremoves bacterial coating from the tongue surface. Step Three: Electric Toothbrush - brushes all tooth surfaces. Step Four: Mouthwash/Rinse -final cleanse and oral balance. Step Five: these strips. The routine is designed so that Step Five operates on the cleanest possible tooth surface - the four preceding steps prepare the mouth for whitening to work at full effectiveness.
