Peter Thomas Roth Water Drench Hyaluronic Glow Serum — 75% Hyaluronic Acid, 5% Ceramide Complex for Long-Lasting Hydration

Peter Thomas Roth Water Drench® Hyaluronic Glow Serum is an intensive hydrating serum that uses a 75% Hyaluronic Acid Complex, 3% HydraFence and a 5% Ceramide Complex to visibly plump skin and deliver long-lasting moisture for a dewy, youthful look.

This lightweight serum layers easily under moisturizers and makeup to flood skin with multi-weight hyaluronic molecules that attract and retain moisture. Mineral-rich Malachite Complex supports skin’s fresh appearance while ceramides target the visible look of fine lines. The formula balances immediate surface hydration with longer-lasting retention technologies so skin appears softer, smoother and luminous without heaviness.

How does this serum hydrate skin effectively?

The formula combines a high-concentration 75% Hyaluronic Acid Complex with smaller and larger molecular weights to hydrate multiple skin layers at once. A 3% HydraFence component is included to help maintain elevated hydration levels after application, while a 5% Ceramide Complex supports barrier resilience and texture smoothing.

• 75% Hyaluronic Acid Complex: multi-weight hyaluronic molecules for surface and deeper hydration
• 3% HydraFence: helps sustain hydration over time
• 5% Ceramide Complex: promotes smoother-looking texture and supports moisture retention
• Malachite Complex: mineral-rich ingredient to help detoxify skin's appearance

Will this reduce the look of fine lines and improve radiance?

While no product can permanently erase lines, the serum’s hyaluronic network visibly plumps and softens the look of fine lines by replenishing moisture. Ceramides complement that effect by improving the appearance of skin texture, and the overall result is a dewier, more luminous complexion.

• Plumps the look of fine lines through intense hydration
• Ceramide Complex improves visible texture and smoothness
• Leaves skin looking dewy and refreshed without greasy residue

How long does the hydration last and what does the research show?

Peter Thomas Roth reports that the 3% HydraFence helped provide enhanced hydration for up to 120 hours after last application in a 28-day study on 41 subjects using the HydraFence formulation twice daily. Results vary by individual, but the formulation is built to combine immediate moisture with measurable moisture retention between applications.

• Study context: 28-day study, 41 subjects, twice-daily application
• Reported average sustained hydration: up to 120 hours after last use
• Real-world results depend on skin type, environment and routine

How should I incorporate this serum into my routine?

Apply a few drops to clean, slightly damp skin morning and evening before moisturizer to maximize hyaluronic acid absorption. It layers well under sunscreen and makeup during the day and pairs with richer creams at night for added nourishment.

• Use on damp skin to boost hyaluronic performance
• Apply morning and night before moisturizer
• Compatible with sunscreens and typical makeup products

Who is this for: The Water Drench® Hyaluronic Glow Serum is ideal for anyone looking to boost surface and deeper hydration, diminish the visible look of fine lines through plumping moisture, and add a dewy finish to their complexion. It suits dry, combination and normal skin types seeking visible moisture, as well as those wanting a lightweight layering serum under SPF or makeup. If you have very oily or acne-prone skin, patch-test first and consult ingredient compatibility with your current routine.

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