Ialuset is a medical device based on hyaluronic acid, designed for the healing of superficial wounds and ulcerations. Its repurposing as an anti-aging treatment for the face, driven by TikTok and Instagram, raises a measurable question: what skin changes are actually observed before and after application, and on what skin types are these results significant?
Composition of Ialuset and limitations for daily facial use
The Ialuset cream contains hyaluronic acid, but also liquid paraffin, propylene glycol, and preservatives. This formulation, designed to protect wounds, is not optimized for daily cosmetic application on the entire face.

Dermatologists have been warning since 2023-2024 about the occlusive and potentially irritating nature of these excipients, especially on sensitive or acne-prone skin. Paraffin forms a greasy film that partially prevents the skin from breathing. Propylene glycol, on the other hand, can cause reactions in allergic individuals.
Several users documenting the before and after results of Ialuset on the face report discomfort or micro-comedones after a few weeks of continuous use, where the immediate benefits (softness, hydration) were indeed real in the first days.

Before and after results of Ialuset on the face: skin profiles and observed differences
User feedback converges on one point: the most noticeable results concern dehydrated or damaged skin. On these profiles, suppleness and dehydration fine lines visibly improve within a few days of application.
In contrast, on skin that is already properly hydrated, the before and after difference is significantly less dramatic. Hyaluronic acid captures water and retains it in the superficial layers of the epidermis, which explains a rapid “plumping” effect, but this effect directly depends on the initial water deficit.
Dehydrated or weakened skin
This is where testimonials are most enthusiastic. Dryness fine lines fade, the complexion appears brighter, and the texture feels different. These improvements generally appear within the first few days of use.
Combination to oily skin
The occlusive film left by paraffin can worsen shine or promote the appearance of comedones. The hydrating effect exists, but the benefit-risk ratio is less favorable than on dry skin.
Mature skin with established wrinkles
Deep wrinkles (nasolabial folds, pronounced forehead lines) do not respond in the same way as superficial fine lines. Topical hyaluronic acid does not have the ability to fill a deep dermal fold. The most realistic “before and after” testimonials on mature skin show an increase in comfort and radiance, not a disappearance of wrinkles.
Off-label use of Ialuset: what the TikTok trend doesn’t show
The popularization of Ialuset as an anti-aging cream via social media relies on off-label use, meaning outside the indication intended by the manufacturer (Laboratoires Genevrier). The product has never been tested or validated as a daily cosmetic treatment for the face.
This distinction has concrete consequences:
- No published clinical studies evaluate the anti-aging effectiveness of Ialuset on the face with prolonged use, unlike cosmetic creams that must prove their claims
- The “before and after” videos on TikTok and Instagram often present very short-term results (a few days), with no follow-up beyond a few weeks
- The lighting conditions, makeup, and angle of the shot vary significantly from one testimonial to another, making objective comparison difficult
The absence of a standardized protocol in these testimonials greatly limits the value of the displayed results. A face filmed in the morning in natural light after hydration will always appear smoother than a face filmed in the evening under artificial lighting.
Topical hyaluronic acid on the face: Ialuset versus cosmetic alternatives
The main active ingredient in Ialuset, hyaluronic acid, is present in a very wide range of cosmetic treatments specifically formulated for the face. The difference lies not in the active ingredient itself, but in the vehicle that carries it.
Cosmetic creams with hyaluronic acid generally use non-comedogenic excipients, lightweight textures suitable for daily application, and formulations dermatologically tested for prolonged facial use. Ialuset, designed for healing, favors a thick protective film that is not intended to be worn all day on healthy skin.
For a facial care routine focused on hydration and wrinkle prevention, a serum or cosmetic cream with hyaluronic acid offers a better balance between effectiveness and long-term skin tolerance.
The before and after results of Ialuset on the face do exist, but they are limited to a specific profile: dehydrated skin, occasional use, targeted application. Beyond a few days, the hydrating benefit stagnates while the risk of irritation increases. The most reliable data remains this: hyaluronic acid works, but the choice of the product containing it matters as much as the active ingredient itself.
