Meet your all-in-one hydration and barrier repair serum. The Essential Hydration Serum intensely hydrates, fortifies and firms to instantly revitalizes dry, dehydrated and irritated skin.

This three-in-one serum combines 35 compounds that are naturally present in your skin - such as Natural Moisturising Factors, Ceramides and Fatty Acids. Think of these ingredients as a protective coat or the building blocks to your skin - they help keep the outer layer of the skin protected against environmental stressors while encouraging the natural skins processes needed to rebuild the moisture barrier for healthy, hydrated skin.

The Essential Hydration Serum is suitable for:

• Dry or chronically dehydrated skin that feels tight, dull or uncomfortable
• Sensitive or reactive skin with a compromised barrier that struggles to retain moisture
• Skin affected by harsh weather, central heating, over-exfoliation or overuse of actives
• Anyone in their 30s and above noticing the first signs of volume loss, fine lines or reduced firmness
• Those using retinoids or other actives who need robust hydration support to maintain barrier health
• Oily skin types looking for a lighter alternative to heavy moisturisers

PrincipHYAL® Cube3
Patented, multi-molecular Hyaluron biotechnology that works in synergy with the skin's own cellular receptors. It delivers a visible lifting effect, improves elasticity and the appearance of fine lines, and stimulates the skin's own hyaluronic acid synthesis over time.

Biomimetic Complex
A blend of 35 compounds naturally present in the skin. The NMF-identical amino acid complex replenishes the skin's ability to attract and hold water. Oat ceramides reinforce barrier structure and protect against environmental degradation. Essential fatty acids Linoleic and Linolenic Acid restore the lipid barrier from within and reduce moisture loss. Together they rebuild and strengthen the skin's natural barrier for healthier, more resilient skin.

Aquaxyl™ — 3D Hydration Complex
A patented plant-derived sugar complex that addresses hydration on three pathways: it reinforces the barrier, optimises the skin's water reserves and improves water circulation. Barrier reinforcement in 24 hours. Visibly softer, smoother skin in 28 days.

Bifida Ferment Lysate
A prebiotic that strengthens the skin's microbiome and supports cellular repair simultaneously helping to calm visible redness, reduce irritation and build resilience against against UV exposure, pollution and daily environmental stress.

Apply morning and evening after cleansing, before moisturiser.

Routine order: Apply after thinner-textured products such as a toner, chemical exfoliant or lighter serums, and before your moisturiser.
