Teeth Whitening Strips at Home: How They Work, How to Use Them, and Why PAP+ Skips the Peroxide
Whitening strips are gel-coated strips worn for 30 minutes a day. How Hismile PAP+ whitens without hydrogen peroxide, how to apply strips, and what to expect.
Whitening strips are thin, flexible strips coated with a whitening gel that you press onto your teeth for a set time — with Hismile PAP+ Whitening Strips, 30 minutes a day. Classic strips rely on hydrogen peroxide. PAP+ strips use phthalimidoperoxycaproic acid (PAP) instead, an oxidising ingredient that lifts stains without peroxide, alongside hydroxyapatite and potassium citrate, which Hismile adds for enamel care and comfort. No trays, no LED light, no appointment: dry teeth, two strips and half an hour on the sofa.
- •One treatment is 1 long strip for the upper teeth plus 1 short strip for the lower teeth, worn for 30 minutes.
- •Hismile PAP+ Whitening Strips hold 7 treatments, a one-week course; V34 Whitening Strips hold 14, a two-week course.
- •PAP+ gel contains no hydrogen peroxide; its whitening ingredient is phthalimidoperoxycaproic acid (PAP).
- •Strips grip best on dry teeth, and coffee, tea and red wine should wait 30 minutes after each treatment.
- •Whitening changes natural teeth only: crowns, veneers and fillings keep their colour.
PAP+ versus peroxide: what is the difference
Most whitening works by oxidation: an active ingredient breaks down the coloured molecules that make stains visible. Hydrogen peroxide is the traditional choice, and it is also the ingredient most associated with the sharp sensitivity many people feel during whitening. PAP is a different oxidiser that does the same job on stains without peroxide. Hismile builds its PAP+ gel around it and adds hydroxyapatite, the mineral enamel is made of, and potassium citrate, an ingredient long used in toothpastes for sensitive teeth. That is the reasoning behind the brand's promise of whitening without the sting.
How to use whitening strips, step by step
Brush your teeth, then dry them thoroughly with a tissue; this is the step most people skip and the reason strips slide. Open one sachet, peel the long strip from its backing and place the gel side on your upper teeth with the edge along the gum line. Press across the front, then fold the excess behind the teeth to lock it in place. Repeat with the short strip on the lower teeth. Leave both on for 30 minutes, lips relaxed, without eating or drinking. Peel, discard, and rinse or brush gently. Use one sachet a day for the length of the course. Whitening strips are for adults; if you are pregnant or breastfeeding, wear braces, or have dental work or gum problems, ask your dentist first.

Pink box or purple box
Hismile makes two strips, and the choice is about pace. The pink PAP+ Whitening Strips are the focused one-week course: 7 sachets, pure PAP+ whitening, the brand's best-selling formula on a strip. The purple V34 Whitening Strips run for two weeks and add V34 colour correction to the same PAP+ idea, so teeth look brighter the moment the strips come off while the whitening builds underneath. They leave a purple film that brushes straight off with your regular toothpaste. Choose pink for a quick, simple course; choose purple if you like seeing a result on day one.
Keeping the result
Whitening is not permanent, because the things that stain teeth are the things most of us enjoy daily. A few habits stretch the result: rinse with water after coffee, tea or red wine, brush twice a day with a fluoride toothpaste, and repeat a strip treatment now and then as maintenance. Between courses, Hismile's V34 Colour Corrector Serum gives an instant brightening top-up in two minutes, and the Strawberry Fluoride+ Toothpaste covers the daily brushing. All four are available in Israel at Skin101.

Original Hismile, not a purple lookalike
Viral products attract copies, and online marketplaces are full of purple V34-style serums and strips from unknown makers; a convincing box tells you nothing about what is inside. Every Hismile product at Skin101 is an authentic, sealed original, with the official batch code and usage instructions on the packaging, delivered across Israel. With something you put in your mouth, that matters: when a price elsewhere looks too good, ask why.
Frequently Asked Questions
Do whitening strips damage enamel?+
Used as directed, whitening strips are designed for home use. Hismile states that its PAP+ formula whitens without harming enamel and includes hydroxyapatite in the gel. Do not exceed the 30-minute wear time or the length of the course, and see a dentist if you have existing dental problems.
How quickly do whitening strips work?+
Hismile says many people notice a difference after the first 30-minute treatment, with the full result at the end of the course: 7 days for PAP+ Whitening Strips and 14 days for V34 Whitening Strips. Results vary with the type and depth of the stains.
Can I use whitening strips if I have sensitive teeth?+
PAP+ strips were created for exactly that concern: they contain no hydrogen peroxide and include potassium citrate, an ingredient used in sensitive-teeth toothpastes. If you feel discomfort that does not pass, stop and speak to your dentist.
