Biologique Recherche Sérum Biosensible
Biologique Recherche Sérum Biosensible is designed for very sensitive, reactive skin. This soothing, calming and strengthening serum helps relieve discomfort, making it ideal after a professional facial.
It helps reduce the feeling of skin sensitivity and alleviates the feeling of tightness while helping the skin feel stronger and more resilient. Its formula of 12 active ingredients brings together soothing ingredients, protecting antioxidant botanicals and hydrating ingredients such as hyaluronic acid and sugar derivatives.
From the first application, the look of redness is reduced and the skin enjoys a genuine sensation of relief and comfort. Always apply it before your cream.
Why we love it
Very sensitive, reactive skin often needs less, not more, and the right serum can make the whole routine feel more comfortable. Sérum Biosensible is the one we think of when the skin feels tight, uncomfortable or easily flushed. We especially love it after a professional facial, when the skin appreciates extra comfort. The flexible schedule, from an intensive course to a twice-weekly maintenance, lets us adapt it to how the skin is responding.

- Helps the skin feel stronger and more resilient
- Helps reduce the feeling of skin sensitivity
- Soothes and helps rebalance the skin's comfort
- Calms the feeling of tightness
- Provides a sensation of comfort
- Helps reduce the look of redness from the first application
