Dermalogica Circular Hydration Face Serum 0.34 fl oz — Hyaluronic Acid, Long‑Lasting Lightweight Hydration

Dermalogica Circular Hydration Face Serum is a lightweight, professional-grade hyaluronic acid serum that delivers immediate and sustained hydration while helping reduce future moisture loss.

This concentrated 0.34 fl oz serum is formulated to kick-start skin’s hydration cycle: it floods the skin with moisture, replenishes reserves from within, and helps lock water in to support a softer, smoother complexion. The watery-gel texture absorbs quickly, layers under moisturizer and makeup, and was developed with skin therapists to address dryness, dullness, and the appearance of fine lines through long-lasting hydration technologies.

How does this serum provide both instant and lasting hydration?

The formula pairs an enhanced form of hyaluronic acid for rapid surface and near-surface hydration with a multi-component matrix that sustains moisture. Active biopolymers and fermented polyglutamic acid help rebuild internal water reserves while plant-derived sugars and amino acids form a barrier to reduce evaporation.

• Enhanced hyaluronic acid for immediate plumping and surface hydration
• Algae extract matrix delivers extended moisture for 10+ hours
• Polyglutamic acid from fermented soy replenishes internal moisture stores
• Surface-trapping sugars and amino acids slow water loss

Will this serum feel heavy or interfere with makeup?

Dermalogica Circular Hydration is a watery-gel serum designed to absorb quickly without a greasy residue, making it suitable to layer under creams and foundations. Because it sits light on the skin, it won’t pill when used alone or beneath your usual skincare and makeup routine.

• Light, non-greasy watery-gel texture
• Fast absorption for easy layering under moisturizer and makeup
• Recommended application: 4–6 drops to face and neck, morning and night

What ingredients support the skin’s hydration cycle?

The serum combines humectants, film-formers, and microbiome-supporting ingredients to support full-circle hydration. In addition to hyaluronic acid and polyglutamic acid, an algae-derived matrix provides sustained release of moisture while a postbiotic blend helps maintain a balanced skin environment.

• Hyaluronic acid for multi-depth hydration
• Fermented soy polyglutamic acid to fortify internal moisture stores
• Algae extract matrix for long-lasting surface hydration
• Plant sugars, amino acids, and postbiotics to trap moisture and support skin balance

How should I add this serum to my skincare routine?

Apply 4–6 drops to clean skin on face and neck morning and night before heavier moisturizers or sunscreens. It pairs well with Dermalogica Hyaluronic Ceramide Mist for extra hydration layering and works under makeup without altering finish.

• Use on cleansed skin, AM and PM, 4–6 drops per application
• Layer under moisturizer, SPF, or makeup once absorbed
• Combine with Hyaluronic Ceramide Mist for enhanced results

Who is this for: Dermalogica Circular Hydration Face Serum is tailored for anyone seeking long-lasting, lightweight hydration—suitable for dry, dehydrated, combination, and normal skin types. It’s a professional-grade option for people who want rapid plumping and sustained moisture without heavy oils or sticky finishes, and for those looking to support skin balance and reduce moisture evaporation over time.
