Product Overview
Sérum Vivant is a daily correcting serum developed for adult seborrheic and blemish-prone skin, including sensitive skin. Inspired by Biologique Recherche’s Masque Vivant, it helps visibly reduce persistent blemishes, blemish-related redness and excess sebum while refining skin texture and supporting the skin barrier without a drying finish.
Its prebiotic, postbiotic and biomimetic approach is designed to support the skin microbiome and restore a clearer, more balanced-looking complexion. In manufacturer testing with twice-daily use, excess sebum was reduced by 27% and skin texture was refined by 19% after 14 days; persistent blemishes were reduced by 42%, associated redness by 21%, and skin-barrier function improved by 19% after 28 days.
Recommended For
- Adult skin with persistent blemishes and blemish-related redness.
- Seborrheic, combination-to-oily or blemish-prone Skin Instants®.
- Sensitive blemish-prone skin that needs targeted care without an overly drying approach.
Texture and Experience
A lightweight, aqueous and subtly gel-like serum that absorbs quickly with a comfortable, non-greasy finish. Its distinctive brown color and singular scent come from the formula’s fermented yeast extract and are characteristic of the Vivant range.
Care Step
Apply morning and evening to the face with upward strokes, avoiding the eye area. Use during the Treatment Stage after cleansing, the recommended Lotion P50 and Masque Vivant, then follow with the Biologique Recherche cream selected for your Skin Instant®.
When layering with other Quintessential Serums, apply Sérum Vivant immediately before Colostrum VG and/or Spectral.
