Hismile V34 Colour Corrector Serum: Complete Review
Dreaming of a dazzling smile worthy of Hollywood's biggest stars? The Hismile V34 Colour Corrector Serum, a product buzzing on social media, promises instantly whiter and brighter teeth. Faced with extremely polarized reviews, we decided to investigate this viral phenomenon.
But how does it work, is it truly effective, and is it safe for your teeth? While this product isn't dangerous, it is certainly one of the most divisive dental products on the market.
What is the Hismile V34 Colour Corrector?
The V34 serum is a topical brightening treatment developed by the Australian brand Hismile. It is crucial to understand that V34 is not a whitening product in the traditional sense. It does not contain peroxide and does not chemically alter the color of your teeth. Instead, it functions as a temporary "concealer" for your smile.
Its unique feature is its intense purple color, which allows it to act like a "purple shampoo" for your teeth.

The Science: How Does V34 Actually Work?
The concept behind V34 is based on the principles of color theory. On the color wheel, purple and yellow are complementary colors, meaning they sit directly opposite each other. When combined, they cancel each other out. By applying a water-soluble, deep violet dye (a combination of D&C Red No. 33 and FD&C Blue No. 1) to the surface of your teeth, the V34 serum temporarily neutralizes and masks yellow tones, revealing a perceptibly brighter, whiter, and less yellow shade.
Is the V34 Corrector Effective? Real-World Results
Hismile's V34 serum promises an instant brightening boost. To verify these claims, we analyzed numerous user testimonials and professional reviews. The consensus is clear: its effectiveness is highly dependent on the user's initial tooth shade and expectations.
For individuals with already light teeth who have some minor yellow undertones (often from coffee or tea), the results can be immediately noticeable and impressive. It excels as a finishing touch after a recent whitening treatment or as a quick brightener before a special event.
However, for those with naturally darker teeth or more significant, deep-set discoloration, the effect is often minimal to non-existent. This explains the conflicting online reviews. V34 is a surface-level color corrector, not a deep whitening solution.
The key takeaway is that V34 is for brightening, not whitening. It optically enhances your smile for a short period. The effect is temporary and will wash away after eating, drinking, or brushing.
Is the Hismile V34 Serum Safe for Your Teeth?
This is a primary concern for potential users, and the answer is yes, the V34 serum is generally considered safe when used as directed. Its formula is designed specifically for dental use.
- Peroxide-Free: It does not contain hydrogen or carbamide peroxide, making it a non-bleaching option suitable for those with sensitivity.
- Non-Abrasive: While it contains hydrated silica, a mild abrasive, it's considered safe for enamel when used with a soft-bristled toothbrush and not brushed too aggressively.
- Safe for Dental Work: It can be used by people with veneers, crowns, or implants, but it will only color-correct natural tooth enamel, not the dental restorations themselves.
As with any oral care product, the American Dental Association (ADA) recommends consulting your dentist before starting a new whitening or brightening regimen.
How to Properly Use the V34 Colour Corrector
For the best results, follow these steps:
- First, brush your teeth normally with your regular toothpaste.
- Apply two pumps of V34 serum to a soft-bristled toothbrush.
- Gently brush your teeth in a circular motion for 30 seconds to 2 minutes.
- Spit out the excess and rinse your mouth thoroughly with water.
Some users report better and less messy results by applying the serum directly to the most yellow areas of the teeth with a cotton swab before brushing.

FAQ: Your Top Questions About the Hismile V34 Serum
No. Hismile V34 is a color corrector, not a chemical whitener. It deposits a temporary purple film on the tooth surface to cancel out yellow tones. The effect is cosmetic and temporary, lasting a few hours until you eat, drink, or brush again.
Hismile suggests it can be used daily. However, some dental professionals recommend using it occasionally, like before special events, due to the presence of mild abrasives like hydrated silica. Daily use with aggressive brushing could potentially harm enamel over time.
The product is safe to use on dental work, but it will not change its color. The color-correcting technology only works on natural tooth enamel. Hismile recommends avoiding brushing the serum directly onto these restorations.
Because it is peroxide-free, V34 is unlikely to cause the chemical sensitivity associated with traditional whitening products. Most users report no sensitivity. However, individuals with pre-existing sensitivity or worn enamel could potentially experience discomfort.
