Peter Thomas Roth Water Drench Hyaluronic Glow Serum — 75% Hyaluronic Complex, Ceramide-rich Plumping Hydration

This lightweight serum layers easily under creams or makeup to deliver concentrated moisture and a luminous look. Formulated with multiple humectant weights, barrier-supporting ceramides, and a mineral-rich malachite complex, it targets dryness and the appearance of fine lines by boosting surface hydration and supporting skin’s moisture retention.

How does this serum hydrate differently from a regular moisturizer?

The formula centers on a 75% Hyaluronic Acid Complex that includes a variety of molecular weights to attract and hold water at multiple skin depths. Alongside that, 3% HydraFence is included to help prolong elevated hydration levels over time, while the 5% Ceramide Complex supports the skin barrier so moisture is retained more effectively.

• 75% Hyaluronic Acid Complex: multi-weight HA for immediate and lasting plumpness
• 3% HydraFence: helps extend skin moisture after application
• 5% Ceramide Complex: reinforces barrier to reduce moisture loss

What visible differences can I expect after using it?

With consistent use, skin typically appears smoother and more dewy, and the look of fine lines can appear softened as surface moisture increases. The mineral-rich Malachite Complex helps refine the look of skin texture and supports a fresher appearance.

• Plumper-looking skin and reduced look of fine lines
• More luminous surface with a hydrated glow
• Refreshed, less-dull-looking complexion from malachite minerals

How should I incorporate this serum into my routine?

Apply to clean, slightly damp skin once or twice daily before heavier creams or oils to lock in moisture. A few drops spread across face and neck are usually sufficient; follow with a moisturizer to seal in hydration, or layer under sunscreen in the morning.

• Use morning and/or night after cleansing and toning
• Apply to damp skin for optimal absorption and plumping
• Finish with moisturizer or SPF depending on time of day

Are there any key ingredients I should be aware of?

The formulation combines humectants, barrier lipids, and mineral extracts for balanced hydration support. It’s free from heavy oils that can weigh down skin, making it suitable for many skin types that want targeted moisture without a greasy finish.

• Hyaluronic Acid Complex: multiple molecular weights for layered hydration
• HydraFence (3%): helps sustain increased hydration levels
• Ceramide Complex (5%): supports barrier integrity and smoothness
• Malachite Complex: mineral-rich extract to support a detoxified look

Who is this for: This serum is designed for anyone seeking intense, multi-day hydration and a dewy, plumped look—especially those with dry, dehydrated, or combination skin who want to reduce the visible appearance of fine lines without heavy creams. It pairs well with antioxidant serums or moisturizers and fits into both morning and evening regimens.
