PearlRx Ectoin Hydro-Shield 4D Hyaluronic Serum

This deeply hydrating serum is formulated by a plastic surgeon to support the skin barrier. The star of the formula is Ectoin, a "desert survival molecule" that forms a microscopic protective water shell around skin cells to lock in moisture and shield against environmental stress.

It works with a 4D Hyaluronic Acid Complex of four molecular weights to hydrate on several levels and plump the look of the skin, while Panthenol (vitamin B5) helps soothe and condition the skin. Free from parabens, SLS and known endocrine disruptors.

THE SURGEON’S HYDRATING SERUM
A deeply hydrating serum formulated by a plastic surgeon to support the skin barrier, centred on the evolutionary survival power of Ectoin. Discovered in extreme desert environments, this natural "extremolyte" molecule allows microorganisms to thrive under blistering heat and total dehydration by wrapping cells in a protective, microscopic hydration shell. On human skin, Ectoin acts as a shield that locks in moisture and helps protect the skin from environmental stress.

The serum's hydrating effects are amplified by our 4D Hyaluronic Acid Complex of four distinct molecular weights (Ultra-Low, Low, Medium, and High) to build a multi-tiered hydration network. It forms a protective layer on the skin's surface, reinforces the moisture barrier and plumps the look of expression lines. Combined with Panthenol (vitamin B5), which helps soothe and condition the skin, the result is a formula that floods the skin with lasting hydration. Free from parabens, SLS and known endocrine disruptors, for resilient, bouncy-looking skin.

Key Benefits:
• Plastic Surgeon Formulated: Formulated to maximise hydration and support skin health.
• Ectoin Desert-Shield Technology: A natural desert extremolyte that builds a protective water shell, helping prevent dehydration and environmental stress.
• 4D Multi-Layer Hydration: Four molecular weights of Hyaluronic Acid to plump the look of lines and lock in surface moisture.
• Free from parabens, SLS and known endocrine disruptors. Housed in BPA-free packaging.

• Daily hydration for all skin types (especially dehydrated or sensitive skin).
• After treatments such as chemical peels, microneedling or laser: use once your doctor says the skin is ready.
• Clean-beauty routines.

The Routine: Integrate this fluid shield seamlessly into your daily skin routine.

Application: Apply morning and evening to clean skin. Dispense a few drops and gently smooth across the entire face, neck area, and the delicate under-eye zone.

Surgeon’s tip: An evening application supports the skin's natural overnight renewal. For the daytime, apply as your foundational base layer, allowing the serum to fully absorb before layering makeup or your PearlRx Mineral Eye Cream on top.
