The root cause of fine lines is water loss — and nothing holds water like Hyaluronic Acid. It absorbs up to 1,000 times its weight in moisture, plumping skin from within and creating a hydration reservoir that lasts far longer than surface-level moisturizers.

This concentrated ampoule pairs Hyaluronic Acid with Cottonseed Extract for barrier-strengthening essential fatty acids and B-vitamins (B6, B10, B12) to support cellular repair and energy production. The result is hydration that goes deeper, lasts longer, and supports skin function rather than just creating a temporary surface sheen. Bio Jouvance Paris delivers this in a concentrated ampoule format suitable for every skin type, every age, and every concern. If you're only going to add one hydration step to your routine, make it this one. The universal ampoule.

Hero Ingredients and Their Benefits:

• Sodium Hyaluronate Acid: Absorbs up to 1,000 times its weight in water, creating a deep moisture reservoir within the skin matrix that plumps fine lines and maintains hydration for hours.
• Cotton Seed Extract: Delivers essential fatty acids that strengthen the skin barrier, reducing transepidermal water loss and helping the skin retain the moisture hyaluronic acid attracts.
• Vitamins B6, B10, and B12: Support cellular energy production and metabolism, helping skin cells utilize the hydration more efficiently for repair and renewal.

How to Use:

Apply the ampoule to clean skin. Massage the face, neck, and decollete using gentle, upward strokes for one to two minutes. Apply the Hyaluronic Acid Creamy Masque on top to seal the beneficial ingredients into the skin. Leave on for 15 to 20 minutes or overnight.

Complete Your Treatment:

Pair with the Hyaluronic Acid Creamy Masque — the sleep-in masque formula continues the deep hydration treatment overnight, amplifying the plumping and moisture-binding effects while you rest.
