Dermalogica Circular Hydration Serum with Hyaluronic Acid | Deep Hydration 1 oz

Deep Hydration That Feels Light

Dermalogica Circular Hydration Face Serum delivers an instant refresh of moisture, with a lightweight feel that layers easily under your favorite moisturizer. The formula uses hyaluronic acid to help plump and hydrate the skin for a dewy, comfortable look that lasts through the day.

Key ingredients that support your hydration goals

• Deep Hydration Boost: Instantly hydrates & plumps skin, lasting 10+ hours.
• Hyaluronic Acid Power: Enhanced HA penetrates deeply for long-term hydration & radiance.
• Moisture Replenishment: Algae extract & Polyglutamic Acid lock in moisture.
• Brightening & Smoothing: Lactic Acid gently exfoliates for a smoother, brighter complexion.
• Balanced Microbiome: Postbiotic blend helps support skin's natural defenses.

In real-life use, you may notice your skin feels more resilient after a routine, similar to a refreshed feel after a good drink of water for the skin. The product is designed to be sensory-friendly: a lightweight, fast-absorbing serum that leaves a subtle healthy sheen rather than a heavy residue.

How to weave this serum into your daily routine

• Apply a few drops to cleansed skin in the morning and/or evening to kick-start the skin’s hydration cycle.
• Follow with your moisturizer to seal in moisture and create a protective veil.

Use cases to consider:

• Dry or dehydration-prone skin that needs a moisture boost without heaviness.
• Those who want a gentle exfoliation with lactic acid to help smooth texture over time.
• If you’re building a routine that supports a balanced microbiome, the postbiotic blend can be a thoughtful addition.

Why choose this serum? It’s a focused, transparent formula designed for a daily ritual rather than a dramatic change, with benefits that accumulate over time and with consistent use. It pairs well with a variety of skin types and climates, from dry indoor air to humid days, offering a flexible approach to hydration that won’t feel heavy or greasy.

Independent clinical testing on 30 subjects over 28 days, with two applications per day, tracked hydration at baseline, 20 minutes, 2 hours, and 10 hours to understand how the serum performs over time.
