Should You Get The HiSmile V34?

If you’re looking for a quick way to brighten your smile before any special event, HiSmile’s V34 Colour Corrector just might be your answer. This innovative purple serum boasts visible effects with minimal hassle. 

While it offers a fast whitening effect, it isn’t the best fit for everyone. At NewMouth, we know that everyone’s smile is unique. Whether you want a quick fix or a long-term transformation, we can help you find the perfect product.

I tried the HiSmile V34 to help uncover if it’s the right choice for your needs and lifestyle. Below, I’ll discuss its pros and cons, my experience, and what customers say so you can decide.

Pros & Cons of HiSmile V34

Here are some things I liked and didn’t like about the HiSmile V34 Colour Corrector after using it: 

What I Like About HiSmile V34

  • Effective whitening. My teeth were a few shades lighter after one use.
  • No sensitivity or gum irritation. It didn’t make my teeth sensitive or irritate my gums like other teeth whitening products I’ve tried.
  • Pleasant taste. The spearmint flavor made brushing more enjoyable.
  • Easy to use. It’s just like brushing with normal toothpaste.
  • Great for special occasions. It’s now my go-to for quick teeth whitening before parties and photoshoots.

What I Don’t Like About HiSmile V34

  • Temporary results. Its effects don’t last long, which can be a dealbreaker if you’re after permanent teeth whitening.
  • Can leave a mess. This stuff gets everywhere once it mixes with water. It leaves purple streaks that need cleaning up.
  • Not ideal for daily use. HiSmile says the V34 has a non-abrasive formula but it contains hydrated silica, a potentially abrasive ingredient.
  • May cause stains. I had to immediately rinse it because the serum left a temporary purple color on my lips and skin if I wasn’t fast enough.

What Ingredients Are Inside HiSmile V34?

HiSmile’s V34 Serum contains tetrasodium pyrophosphate and hydrated silica, making it unique from its other whitening products.1

Since it has a different formulation from HiSmile’s PAP+ Whitening Strips, I decided to investigate its ingredients with the help of our research team. 

Here’s what I found out about them:

My Experience Using The HiSmile V34

I tried the HiSmile V34 Serum and will talk about my experience, including:

  • Before and after results
  • Sensitivity and other side effects
  • Ease of use and application

Before & After Results

I used Hismile’s Colour Corrector one time. Here’s what my teeth look like:

The before photo shows my teeth as being fairly white with noticeable yellow staining along the edges and near the gums. 

On the other hand, the after photo shows how the yellow tint around the edges of my teeth seemed to disappear almost completely.

Overall, I was thrilled by how fast it worked. Not only did my teeth lighten, but their brightness also evened out. Based on my experience using the V34 Colour Corrector, you should see results after one use. The effects will be more vibrant if you use the product frequently.

The HiSmile V34 didn’t give me the uneven results I typically notice from my routine at-home teeth whitening treatments.

Sensitivity & Other Side Effects

The main ingredients in HiSmile’s V34 Colour Correcting Serum—hydrated silica and TSPP—are generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA). However, they carry a few risks:5,6

  • Dental products containing hydrated silica can damage the enamel if you brush too hard or don’t use a soft-bristled toothbrush. It can also cause sensitive teeth when used on enamel that’s already worn out.7
  • TSPP can irritate your gums and the insides of your mouth.8

Did it irritate my gums or cause sensitivity? Not at all! But there were a few customers who did, especially after using it for several days. 

As with any product, each person will have a different reaction to its ingredients. It depends on your teeth and how often you use it.

Ease of Use & Application

The V34 Colour Corrector was straightforward to use. It works like regular toothpaste and placed some on my toothbrush.

I brushed it on my teeth and it had a refreshing minty taste. Its texture was also perfect—smooth with just the right amount of thickness.

Can you use it every day? HiSmile says you can use it daily to conceal yellow teeth stains. I recommend using it occasionally since it has potentially abrasive ingredients that can wear out your tooth enamel.1

You should also use a soft toothbrush to avoid damaging the enamel, which can increase your risk for tooth sensitivity.

What Customers Say About HiSmile V34

The HiSmile V34 Colour Corrector Serum received 3.4⭐ from more than 57,000+ Amazon reviews. I asked our team at NewMouth to gather these reviews and identify recurring themes.

Below is a summary of what people think of the product:

HiSmile V34 Pros

Customers usually enjoyed its flavor and how well it cleans teeth:

“It tastes great! No strong taste or aftertaste.”

Amazon Review

“It does actually clean your teeth and make them shiny.”

Amazon Review

“I like the taste of it though that’s quite nice. Normal teeth whitening stuff tastes horrible.”

YouTube Review

HiSmile V34 Cons

According to some reviews, the product did not provide the dramatic or long-lasting whitening effects shown in advertisements: 

“It is going to temporarily brighten and whiten your teeth, but let’s be real. If you eat something or if you drink something that is going to stain your teeth, the white is just gonna wash away.”

YouTube Review

“It tastes good, and does work. Just not as demonstrated.”

Amazon Review

Several customers complained of the stains it left:

“I personally can’t see a huge difference except for the fact my bottom lip and my gum line is now purple.”

Amazon Review

“It has stained everything in sight. My gum line and my lips are now purple. I have also stained the towel that I wipe my mouth with.”

YouTube Review

Others found it too messy and inconvenient:

“It’s very drippy so you have to be careful. You can get like really dark purple dyes over you if you’re not careful.”

Amazon Review

Final Thoughts on HiSmile V34 Colour Corrector

The HiSmile V34 Colour Corrector is a surprisingly fast and effective way to brighten your smile. I was impressed with how it evened out the tone of my teeth after just one use. Its easy application makes it a convenient addition to any routine, especially when you need a quick confidence boost.

However, it’s important to manage your expectations. Its results are temporary and it can leave quite a mess. Due to its potentially abrasive nature, I don’t think it’s the best choice for everyday use. 

If you’re looking for a long-term whitening solution or have sensitive teeth, you may want to explore other options:

  • For sensitive teeth: HiSmile’s PAP+ Teeth Whitening Strips contain ingredients that strengthen the enamel and reduce sensitivity.
  • For better value: Auraglow offers 20 treatments and a reusable LED mouthpiece that speeds up teeth whitening for $48.
  • For lasting effects: Snow whitens teeth within days and requires little upkeep (one or two times weekly) to maintain your results.
