Dermalogica Circular Hydration Hyaluronic Acid Face Serum, 2 fl oz — Lightweight, Long‑Lasting Hydration

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

Formulated with an enhanced form of hyaluronic acid, polyglutamic acid, algae-derived hydration matrix and a postbiotic blend, this watery-gel serum was developed with skin therapists to support skin’s natural moisture cycle. It soaks in quickly, layers smoothly under moisturizers and makeup, and is designed to visibly restore suppleness and radiance without feeling heavy.

How quickly will I notice hydration?

Visible and tactile hydration is immediate: the watery-gel texture floods the surface so skin feels quenched right after application. The formula also contains ingredients that continue to draw and hold moisture over time for extended comfort.

• Instant water-binding from enhanced hyaluronic acid for immediate plumping
• Algae-derived matrix: sustained hydration for 10+ hours
• Polyglutamic acid helps replenish moisture reservoirs inside the skin

Will this serum help prevent moisture evaporation?

Yes — multiple humectant and film-forming components work together to reduce transepidermal water loss. Plant-derived sugars and amino acids create a moisture-locking layer, while the postbiotic blend supports skin balance for healthier-looking hydration behavior.

• Surface-trapping sugars and amino acids that limit evaporation
• Postbiotic blend to support microbiome balance and resilience
• Lightweight film that doesn’t feel greasy under moisturizer

How does this serum fit into my routine?

Apply 4–6 drops to clean face and neck morning and night, before your moisturizer and sunscreen during the day. It layers well under makeup and pairs effectively with Dermalogica’s Hyaluronic Ceramide Mist for added hydration boost.

• Use after cleansing and toning, before moisturizer
• Works with all skin types, including dry and combination
• Recommended combo: Circular Hydration Serum + Hyaluronic Ceramide Mist

Is the texture suitable for sensitive or oily skin?

The watery-gel formula absorbs rapidly and is formulated to feel weightless, making it suitable for a broad range of skin types. If you have very reactive skin, patch testing is recommended, and you can use fewer drops to assess tolerance.

• Non-greasy, fast-absorbing watery-gel texture
• Layerable under other products without pilling
• Recommended patch test for highly reactive skin

Who is this for: Dermalogica Circular Hydration Face Serum is aimed at anyone seeking immediate and long-lasting hydration—those with dry, dehydrated, dull or fine-line-prone skin, plus people who want a lightweight serum that layers well under skincare and makeup. It’s also suitable for clients and professionals looking for a therapist-developed hydrator to integrate into daily regimens.
