HiSmile V34 Colour Corrector Serum

Product Description

• A peroxide-free, instant “concealer for your teeth” that masks yellow tones via colour-correcting technology using purple pigments to neutralize yellow hues. 

• The formula contains dyes (D&C Red No. 33, FD&C Blue No. 1), glycerin, peppermint oil, hydrated silica, xylitol, tetrasodium pyrophosphate, among other ingredients. It’s described as non-invasive, gentle, and safe for dental work or enamel, making it suitable even for sensitive teeth. 

Uses & Benefits

• Instant Brightening Effect: Gives a temporary whitening effect by masking surface yellowing—great for photos or special occasions. 

• Easy to Use: Typically applied with 2 pumps onto a toothbrush and brushed for about 2 minutes; avoid rinsing off fully to preserve effect. 

• Gentle on Oral Tissues: Made without peroxide and formulated to be enamel-safe and sensitivity-friendly.Considered portable and suitable for quick touch-ups.

Limitations & Criticisms

• Very Short-Lived Results: Often lasts less than an hour. Reviewers and testers often liken it to makeup— for aesthetic, momentary effects, not whitening.

• Messy Application: The runny, sticky purple serum can drip, stain sinks/toothbrushes, and is generally messy if not applied carefully. 

• Inconsistent Efficacy: Clinical and user reviews vary—some report minimal to no change. 

Precautions & User Experiences

• Irritation Risks: A few users reported sensitivity or gum issues, though such cases are anecdotal.

• Possible Negligible or Negative Outcomes: Several Reddit users warn about poor results, misleading ads, and even worsening appearance:

  “...it doesn’t work in fact it makes it worse... offset the color of these surface level stains and honestly enhance other stains, making your teeth look worse than you started...” 
  Also:
  “I used the v34 serum … started noticing my bottom gums receding … bleeding … my teeth are so sensitive.” 

• Not ADA-Approved: The American Dental Association doesn’t recognize colour-correcting products like V34 as legitimate whitening—they’re cosmetic. 

• Not a Substitute for Fluoride Toothpastes: Since it lacks fluoride, it's not meant to replace everyday toothpaste—best used as a cosmetic finish.

• Review Manipulation Concerns: Some users allege the brand hides negative feedback or misrepresents efficacy—but these are user opinions and should be weighed with caution. 

  Final Take

  If you're looking for a quick visual boost right before an event, the V34 Serum might serve as a fun, temporary aesthetic tool. However, it’s far from a whitening treatment and is best used sparingly. If long-term results or oral health is your priority, relying on professional whitening or ADA-approved products is smarter.
