Dermalogica Circular Hydration Face Serum — 1 fl oz hyaluronic acid serum for immediate + long‑lasting moisture

Dermalogica Circular Hydration Face Serum is a lightweight, professional-grade hyaluronic acid serum that floods skin with immediate moisture, rebuilds internal hydration reserves, and helps reduce surface water loss for long-lasting softness.

This serum combines an enhanced form of hyaluronic acid with polyglutamic acid, algae-derived matrix technology, plant sugars and a postbiotic blend to target hydration from multiple angles. Designed by skin therapists, it absorbs quickly and layers under moisturizers and makeup, providing sustained comfort for dry, dehydrated, or dull skin without feeling heavy.

How does this serum deliver both immediate and lasting hydration?

The formula pairs a fast-acting hyaluronic acid that draws water into the skin’s surface with ingredients that reinforce moisture retention. Polyglutamic acid supports deeper water reserves while an algae matrix slowly releases hydration over time.

• Enhanced hyaluronic acid floods surface moisture quickly for instant plumpness.
• Polyglutamic acid helps replenish and hold water inside skin layers.
• Algae-derived matrix provides gradual, sustained hydration for 10+ hours.

Will it feel heavy or interfere with makeup?

The serum is a watery-gel with a lightweight texture that absorbs rapidly and doesn’t leave a greasy residue. It layers well beneath daily moisturizers, sunscreens, and cosmetics so it won’t disrupt your routine.

• Fast-absorbing watery-gel consistency for comfortable wear.
• Non-greasy finish that won’t pill under makeup products.
• Works smoothly under day or night skincare steps.

What ingredients help prevent future hydration loss?

Plant-derived sugars and amino acids form a barrier on the skin’s surface to reduce evaporation, while a postbiotic complex supports a balanced microbiome that helps maintain healthy-looking hydration. These components work together to protect moisture once it’s been delivered.

• Surface-binding sugars and amino acids lock in moisture and reduce transepidermal water loss.
• Postbiotic blend helps support the skin’s natural ecosystem for resilient hydration.
• Complementary ingredients target both immediate and ongoing water retention.

How should I use this serum for best results?

Apply 4–6 drops to clean skin on the face and neck, morning and night, then follow with your moisturizer or sunscreen. For layered hydration, combine with a mist or hydrating cream to amplify the serum’s moisture-holding benefits.

• Use twice daily on cleansed skin: 4–6 drops per application.
• Layer under moisturizer and sunscreen during the day.
• Pair with Hydrating Mists or creams to maximize lasting hydration.

Who this is for: Dermalogica Circular Hydration Face Serum is suitable for all skin types that need improved moisture—especially dehydrated, dry, or dull skin looking for fast-plumping hydration without weight. It’s ideal for anyone seeking a professional-grade, easy-to-layer serum to add to morning and evening regimens, and for those who prefer evidence-driven ingredient blends developed with skincare professionals.
