Biologique Recherche's high-performance serum addresses severe skin dehydration and supports long-lasting hydration. Formulated with hydro-fixing ingredients and plant-based humectants, this serum binds moisture deep within the skin, helping cells lock in hydration and rebuild barrier integrity.

The water-rich texture comforts dryness immediately while restoring the skin’s ability to retain moisture over time. With consistent use, dryness is visibly relieved, sensitivity is reduced, and skin feels noticeably more supple, balanced, and calm—without heaviness or residue.

SKIN SCIENCE

• Skin can lose 800 to 1,000 ml of water per day.
• This natural water loss is worsened by internal and external stressors.
• When the skin’s moisture barrier is compromised, dehydration becomes chronic.
• Hydrating actives help restore water levels and support barrier function.
