Peter Thomas Roth Water Drench Hyaluronic Glow Serum — 75% HA Complex & 3% HydraFence for Plumping Hydration

Peter Thomas Roth Water Drench® Hyaluronic Glow Serum is an intensive hydrating serum that uses a 75% hyaluronic acid complex plus 3% HydraFence to visibly plump and boost skin's moisture and radiance.

This lightweight, fast-absorbing serum is formulated to flood skin with multiple weights of hyaluronic acid, support longer-lasting hydration with a barrier-enhancing HydraFence blend, and refine the look of fine lines with a ceramide complex. Mineral-rich malachite helps clarify the look of skin while leaving a fresh, dewy finish. The formula is designed for daily layering under creams or makeup to keep skin appearing supple and luminous.

How does this serum deliver deep hydration?

The serum combines a high concentration of hyaluronic acid in varying molecular sizes to attract and bind water at different skin layers. A targeted HydraFence component is included to help maintain elevated hydration levels for days after application in clinical testing. Together, these ingredients support a visibly plumper surface and smoother texture.

• 75% hyaluronic acid complex with multi-weight HA molecules
• 3% HydraFence to help sustain hydration up to 120 hours
• Fast-absorbing, non-greasy liquid texture suitable for layering

Will it help improve the look of fine lines and texture?

A 5% ceramide complex is included to help improve the appearance of fine lines by reinforcing the skin’s moisture-holding structure. As hydration increases, skin surface irregularities appear softened and lines look less pronounced. Results are cosmetic; expect smoother-looking skin rather than structural changes.

• 5% ceramide complex to support the look of firmer, smoother skin
• Hydration-driven plumping effect reduces visible lines
• Suitable to pair with serums or moisturizers for layered benefits

What other active ingredients are in the formula and why they matter?

Alongside hyaluronic acid and ceramides, a malachite mineral complex is added to help clarify the look of skin by targeting visible impurities and environmental stressors. The overall blend focuses on moisture retention, surface radiance, and a refreshed appearance. The lightweight profile keeps the skin dewy without heaviness.

• Mineral-rich malachite for detoxifying and refining appearance
• Combination of humectants and barrier-support agents for balanced hydration
• Formulated for everyday use under creams or makeup

How should I use the serum in my routine?

Apply morning and evening after cleansing and before heavier treatments or moisturizers. Use a few drops and gently press into damp or dry skin to lock in moisture. For enhanced results, follow with a hydrating cream or oil to seal the benefits.

• Use 1–3 drops on clean skin, AM and PM
• Press gently into face and neck; follow with moisturizer
• Safe to layer beneath sunscreen and makeup

Who is this for: This serum is designed for anyone seeking immediate and lasting-looking hydration—especially those with dry, dehydrated, or combination skin who want a dewy finish and reduced appearance of fine lines. It works well for people looking to boost moisture before makeup application or as a daily hydration step in both morning and evening routines. Avoid if you have known sensitivities to any listed ingredients; patch-test if you have reactive skin.

• Ceramide complex helps improve the look of fine lines and wrinkles
• Mineral-rich malachite complex detoxifies the skin
• Skin felt refreshed with moisture
