Dermalogica Hydrating Face Serum — Circular Hydration, 2 fl oz, Hyaluronic Acid & Long‑Lasting Plumping

Dermalogica Circular Hydration Face Serum is a deep‑acting hyaluronic acid serum designed to deliver immediate plumping hydration and sustain moisture for hours while supporting the skin’s natural hydration cycle.

This lightweight serum combines multiple humectants and skin‑supporting actives in a fast‑absorbing formula to restore surface moisture, reinforce barrier function, and improve skin texture over continued use. Clinically measured hydration gains were observed after twice‑daily application across 28 days, and the product is formulated to be incorporated into morning and evening routines under moisturizers or mixed with other serums.

How quickly will I feel skin hydration after applying the serum?

You should notice an immediate smoothing and plumping sensation as humectant molecules draw water into the top layers of skin. The formula is created to absorb rapidly without leaving a sticky finish so it layers easily under creams and sunscreen.

• Fast-absorbing texture that delivers instant softening.
• Hyaluronic acid complex attracts and binds moisture for visible plumping.
• Leaves a non-greasy base for subsequent products.

Will it keep skin hydrated through the day or night?

The serum is engineered for extended hydration, with clinical testing indicating elevated moisture levels that persist for 10+ hours after application. Supporting ingredients help reduce moisture loss and encourage a more resilient skin surface over time with consistent use.

• Long‑lasting hydration that helps maintain skin comfort for hours.
• Polyglutamic acid and algae extract help lock in water.
• Postbiotic blend supports the skin’s natural moisture‑retaining functions.

How does this serum improve skin texture and tone?

In addition to hydrating, the formula includes gentle lactic acid to promote mild exfoliation that smooths and brightens the complexion without harsh irritation. With regular application you can expect a visibly more even surface and enhanced radiance as dead surface cells are refined and moisture balance improves.

• Low-concentration lactic acid promotes gentle surface renewal.
• Enhanced hyaluronic acid system supports bounce and smoothness.
• Combined soothing and brightening actives minimize roughness and dullness.

Is it suitable for sensitive or combination skin types?

The serum is formulated to balance microbiome support and hydration, making it compatible with many skin types including combination and some sensitive skin. Start with a patch test if you have known sensitivities, and use every other day initially to gauge tolerance when introducing exfoliating acids.

• Postbiotic blend aimed at supporting the skin’s natural defenses.
• Gentle lactic acid concentration to reduce irritation risk when used correctly.
• Non‑heavy feel that suits layered routines for mixed skin types.

Who is this for: Dermalogica Circular Hydration Face Serum is ideal for anyone seeking fast, visible hydration and improved skin texture—especially those dealing with occasional dehydration, dullness, or barrier fatigue from environmental stressors. It’s well‑suited to people who prefer lightweight serums that play well with moisturizers and sunscreens, and to skincare users wanting measurable hydration support from humectants plus gentle renewal. Avoid using alongside strong exfoliants until you confirm tolerance, and consult a dermatologist if you have severe sensitivity concerns.

• Features: Deep Hydration Boost for immediate plumping that lasts 10+ hours.
• Key actives: Hyaluronic Acid complex, Polyglutamic Acid, algae extract for moisture retention.
