Clarins Hydra-Essentiel Intensive Moisture Quenching Bi-Phase Serum 50ml is a lightweight, dual-phase hydrating serum designed to plump, refresh and visibly improve thirsty skin. Two complementary hyaluronic acids — paired with Clarins's signature plant actives — deliver an immediate burst of moisture and longer-term hydration support.
About Clarins
Clarins is a French family-owned beauty and skincare house founded in Paris in 1954 by Jacques Courtin-Clarins, originally as a beauty institute focused on plant-based skincare. The brand has remained committed to its botanical heritage. The Hydra-Essentiel range is Clarins's flagship hydration line, and the Bi-Phase Serum is its most concentrated hydrating treatment.
Key ingredients
- Hydrolysed Hyaluronic Acid (low molecular weight): penetrates deeper into the upper layers of the skin for inside-out plumping.
- Sodium Acetylated Hyaluronate: a longer-lasting hyaluronic derivative that supports surface moisture retention.
- Organic Leaf of Life (Kalanchoe Pinnata) Extract: a Clarins signature plant active, known for its hydrating properties.
- Organic Saffron Flower (Crocus Sativus) Extract: rich in polyphenols, supporting skin's natural defences.
- Glycerin and Betaine: classic humectants for additional hydration.
- Vitamin E (Tocopheryl Acetate & Tocopherol): antioxidant protection.
Key benefits
- Intensely hydrates and plumps thirsty, dehydrated skin.
- Smooths the appearance of fine, dehydration-related lines.
- Refreshes the complexion and helps revive a healthy, glowing finish.
- Refines skin texture for a softer, more refined surface feel.
- Lightweight bi-phase texture — shake to combine — that absorbs quickly without stickiness.
Who it's for
This serum is designed for all skin types that need extra hydration — particularly normal-to-dry, dehydrated and stressed skin. It is a smart year-round addition to any routine, but particularly welcome in winter, in air-conditioned environments, after long-haul travel and following heavier active treatments (retinoids, acids, vitamin C).
How to use
- Cleanse and tone the skin in the morning and evening.
- Shake the bottle well to combine the two phases of the serum.
- Dispense one or two drops into the palm and warm slightly between fingertips.
- Smooth gently over face and neck, working outwards from the centre.
- Follow with your usual moisturiser. In the morning, finish with a broad-spectrum sunscreen.
