Overview
Biotherm was originally started in France by an independent company that began following the discovery that a specific type of fermented bacteria that grows in the mineral-rich waters of that country (called Vitreoscella Ferment) produces a smoothing and balancing effect on human skin. After a moderate degree of success, Biotherm was purchased by cosmetic giant L’Oreal, which now owns and controls the distribution of the Biotherm brand. Biotherm currently offers several formulas to promote treatment of the eye area, but curiously enough does not offer these formulas together in any sort of combination that would help keep costs low for the consumer. Despite this, we decided to review its Biotherm Lift Eye Contour (for crow’s feet and fine lines) and Hydra-Deto2X (for dark circles and puffiness).

Featured Ingredients
Unfortunately, we were unable to complete our review of the Biotherm products at this time, since the company does not disclose what ingredients are included to achieve their specified results. The only information we were able to gather on Hydra-Deto2X is that it includes a proprietary compound called OxyDetox Complex. But Biotherm does not disclose what this ingredient complex contains, nor does it cite any research proving that it in fact encourages the retention of oxygen in the skin or any detoxification effect that could reduce dark circles or puffiness. Likewise, the Lift Eye Contour description only contains claims that it can reduce crow’s feet, without any explanation of how the formula accomplishes this. In fact, other than the company’s patented Vitreoscella Ferment, the team at EyeWrinkleReviews.com is not sure what any Biotherm products contain.

Web Site Description
The Biotherm web site is attractive and fairly easy to navigate. Products are categorized by their primary function, and the descriptions are clear. But this does not make up for the fact that no information is available on the ingredients in any of its eye treatment formulas. In addition, the web site does not post any scientific references on Vitreoscella Ferment or any substantiation for its positive effects on the skin. We wonder why the company would keep this information from the public, but unfortunately this makes it impossible to conduct an independent review of Biotherm.

Positives
- Company has a unique story of its founding

- Offers a patented and proprietary ingredient for the skin (Vitreoscella Ferment)

 Negatives
- No information about any ingredients in its products are provided

- Web site does not contain any scientific information about ingredients or effects

- No free trial of products is available

- Biotherm does not offer an eye treatment system; products must be purchased individually

Conclusion
Although we were initially intrigued by Biotherm’s story of origination - and impressed by its association with L’Oreal - we honestly cannot recommend any of its eye treatment formulas at this time, since no information is provided about ingredients or effects.
