Meet the New Biologique Recherche Sérum Vivant

A New Daily Solution for Persistent Adult Blemishes

Biologique Recherche has introduced a new innovation for adult skin experiencing persistent blemishes, excess oil and blemish-related redness: Sérum Vivant.

Inspired by the cult-favorite Masque Vivant, this concentrated daily serum is designed to help rebalance blemish-prone skin while supporting comfort and the skin barrier. Rather than aggressively drying the complexion, its modern formula takes a microbiome-conscious approach to creating clearer, calmer and more even-looking skin.

What Makes Sérum Vivant Different?

Adult blemishes often appear alongside sensitivity, dehydration or slower skin recovery. Sérum Vivant was developed to address imperfections while respecting this more delicate skin environment.

The formula combines three complementary technologies:

• Yeast extract: The signature Vivant postbiotic helps address the look of blemish-related redness.

• Inulin: A prebiotic that supports the skin’s microbiome and natural balance.

• Polylysine: A gentle biotech ingredient that targets persistent imperfections.

Together, these ingredients help purify and rebalance the complexion without compromising comfort.

The Benefits of Sérum Vivant

With consistent use, Sérum Vivant is designed to help:

• Visibly reduce persistent adult blemishes

• Minimize blemish-associated redness

• Regulate the appearance of excess sebum

• Refine uneven-looking skin texture

• Support the skin barrier

• Promote a clearer, more balanced complexion

In Biologique Recherche testing, twice-daily application was associated with a 27% reduction in excess sebum and 19% improvement in skin-texture refinement after 14 days. After 28 days, testing reported a 42% reduction in persistent blemishes, 21% reduction in blemish-associated redness and 19% improvement in the skin barrier, measured through reduced water loss. Study sizes were small—19 to 21 volunteers—and individual results will vary. View the official Sérum Vivant information and study details

Who Is Sérum Vivant For?

Sérum Vivant is recommended for blemish-prone Skin Instants®, particularly adult complexions experiencing:

• Recurring or persistent imperfections

• Excess shine and visible sebum

• Redness associated with blemishes

• Uneven or congested-looking texture

• A compromised or uncomfortable skin barrier

Because every Skin Instant® is different, a professional skin analysis can determine whether Sérum Vivant is appropriate for you and how it should be combined with the rest of your routine.

How to Use Sérum Vivant

Apply Sérum Vivant morning and evening to the face using gentle upward movements, avoiding the eye area.

Biologique Recherche recommends using it during the treatment stage of your routine—after cleansing and your professionally selected Lotion P50 and before your prescribed cream. When layering it with Colostrum VG or Sérum Spectral, apply Sérum Vivant first.

Your ideal order of application may vary according to your current skin condition, so personalized guidance is recommended.

A New Chapter in the Vivant Legacy

The new Sérum Vivant brings the purifying philosophy of Masque Vivant into a sophisticated daily formula. It offers a progressive approach for adults who want to address persistent blemishes while maintaining hydration, comfort and barrier support.

At MW Skincare, we believe that blemish-prone skin should never be treated with a one-size-fits-all routine. A personalized Skin Instant® consultation allows us to assess your skin and design a complete Biologique Recherche protocol around its present needs.
