The Smilist has a rating of 4.3 out of 5 on Trustpilot and has accumulated thousands of customer reviews. The Night Whitening Enamel Serum and the remineralizing whitening toothpaste account for the vast majority of reviews. Between the before/after photos shared on social media and the critiques pointing to disappointing results, the portrait of the French brand remains mixed. Here’s what the available data actually allows us to affirm.
Before/After Results of The Smilist: What Clinical Data Doesn’t Say
Before/after photos circulate abundantly on Instagram and in sponsored articles. The brand highlights figures showing whitening progress over several weeks of use. The problem lies elsewhere: no published independent clinical study documents these results.

The available numerical data comes from the brand itself or marketing materials, without detailed external protocols or peer validation. When a user posts a visual comparison of their teeth, the shooting conditions (lighting, exposure, white balance) almost always vary between the initial shot and the final shot. A comprehensive analysis of The Smilist reviews before and after shows that the perception of whitening varies significantly among profiles.
This lack of independent proof does not mean the product is ineffective. It means that the distinction between marketing promise and measurable result remains unclear for the consumer seeking objective feedback.

Negative Reviews of The Smilist: Recurring Profiles of Disappointment
Negative feedback does not distribute randomly. By browsing Trustpilot reviews and forums, three categories of dissatisfaction regularly emerge.
- Users with already minimally stained teeth describe a slight “shine” rather than a visible whitening. When expecting several shades of difference, disappointment is logical.
- Deep stains related to tobacco, coffee consumed in large quantities, or certain medications are more resistant. Several reviews mention a complete lack of change after the recommended full cycle.
- Some critiques focus on packaging: tubes perceived as insufficiently filled, serum bottles deemed fragile. The brand consistently responds that the air space in the tube is intentional and related to the manufacturing process.
The type of dental staining directly influences the perceived result. A serum without hydrogen peroxide primarily acts on surface stains (tea, wine). Intrinsic pigmentation, related to age or medication causes, falls under professional dental treatment.
The Question of Review Moderation
A more sensitive complaint appears in some Trustpilot comments: the suspicion of censorship. Several users claim that their negative reviews have been flagged or removed. Field feedback varies on this point, as Trustpilot has its own verification and reporting system, and the brand can contest a review it deems non-compliant with the platform’s terms of use.
Without access to moderation logs, it remains difficult to determine between active censorship and normal application of Trustpilot rules. This ambiguity fuels distrust among some consumers.
Composition of The Smilist Serum and Toothpaste: What Actually Works
The formula of the Night Whitening Enamel Serum is based on a complex called Floral Microbiotic, combining prebiotics and a patented solidago flower extract. The stated goal is twofold: to act on the color of the enamel and rebalance the oral microbiome.
The toothpaste includes hydroxyapatite, a mineral used in dental care to remineralize the surface of the enamel. Fermented pomegranate enzymes complete the formula. The entire product is certified organic and vegan, without hydrogen peroxide.
The absence of peroxide is a deliberate choice. Peroxide-based products are regulated and reserved for professionals above a certain concentration threshold. The Smilist positions itself in a “gentle” niche, which explains both the good tolerance reported by the majority of users and the more modest results on marked discolorations.
Hydroxyapatite and Whitening: A Nuance to Understand
Hydroxyapatite remineralizes and smooths the surface of the enamel. A smoother enamel reflects light better, giving the impression of whiter teeth. However, this action does not change the intrinsic shade of the tooth. The difference with a peroxide treatment performed in a dental office is structural, not just a matter of dosage.
The Smilist vs. Professional Dental Whitening
Comparing The Smilist to professional whitening amounts to comparing two categories of products. The serum is a cosmetic maintenance treatment. In-office whitening uses high-concentration chemical agents, under supervision, with measurable results in one to two sessions.
The price of the serum falls within the premium range of online oral care products. Whitening at the dentist costs significantly more but produces faster and clinically documented results. For superficial stains related to diet, a peroxide-free serum may suffice to maintain brightness between two cleanings. For established discoloration, expectations should be calibrated accordingly.
The Trustpilot rating of 4.3 out of 5 reflects majority satisfaction. Satisfied users highlight the pleasant taste, absence of dental sensitivity, and ease of integration into a nighttime care routine. Those disappointed share a common point: expectations based on the results of professional whitening applied to a cosmetic product. This mismatch between perceived promise and the actual category of the product remains the main generator of negative reviews.
