THE SCIENCE BEHIND
Serum Vivant is proven to help correct persistent blemishes and rebalance the skin through 3 complementary active ingredients:
- Yeast Extract: the Vivant signature postbiotic, helps target blemish-related redness and support blemish-prone skin
- Inulin: the prebiotic that helps support the skin microbiome
- Polylysine: the gentle blemish-targeting biotech ingredient


THE RESULTS SPEAK FOR THEMSELVES
The skin gradually regains its balance. More comfortable day after day, it appears clearer and visibly more even:
• 27%¹ reduction in excess sebum and 19%² more refined skin texture after just 14 days
• 42%³ reduction in persistent blemishes and a 21%³ reduction in the intensity of redness associated with blemishes after 28 days
In addition to the results measured in laboratory studies, before-and-after photographs demonstrate a visible and progressive improvement in the skin's appearance⁴.

A Unique Sensory Signature
An instantly recognizable sensory identity: its distinctive brown hue and singular scent, both emblematic signatures of the Vivant range. Rather than being masked, these characteristics reflect the richness and complexity of its fermented yeast extract, the cornerstone of the formula.
Its lightweight, aqueous, and subtly gel-like texture glides effortlessly onto the skin and absorbs quickly, leaving a comfortable, non-greasy finish.
