Dermalogica Circular Hydration Face Serum 1 fl oz — Hyaluronic Acid, Deep Long-Lasting Hydration

Dermalogica Circular Hydration Face Serum is a lightweight, long-lasting hyaluronic acid serum designed to deeply hydrate skin for 10+ hours while supporting sustained moisture over time.

This concentrated 1 fl oz serum uses layered humectants, moisture-locking polysaccharides and gentle exfoliation to help skin feel plumper, smoother and more resilient. Formulated to jump-start and sustain skin’s hydration cycle, the formula blends enhanced hyaluronic acid with polyglutamic acid, algae extract, lactic acid and a postbiotic complex to address short-term moisture and long-term hydration capacity without heavy residue.

How quickly will I notice hydration after applying the serum?

Immediate plumping and surface hydration are visible shortly after application, with clinically measured improvements at 20 minutes that continue through 10+ hours. Regular twice-daily use supports increasing baseline hydration over weeks.

• Visible plumpness within minutes
• Clinically measured hydration at 20 minutes, 2 hours and 10 hours
• Designed for twice-daily application to boost cumulative effects

What ingredients make this serum hold moisture for longer?

The serum combines multiple water-binding and moisture-sealing actives. Enhanced hyaluronic acid draws and retains water in the skin, while polyglutamic acid and algae extracts help lock in that moisture for extended comfort.

• Hyaluronic acid variants for deep and surface hydration
• Polyglutamic acid to form a moisture-retaining film
• Algae extract to support water retention and skin texture

Will it change skin texture or tone with continued use?

Yes — the formula includes mild lactic acid to promote gentle exfoliation, which can smooth texture and brighten the complexion over time. A postbiotic blend supports a balanced skin barrier to help maintain those improvements.

• Lactic acid refines skin surface for smoother feel
• Postbiotic components encourage a healthy skin microbiome
• Consistent use can lead to improved radiance and resilience

How should I include this serum in my daily skincare routine?

Apply to clean, slightly damp skin morning and night before moisturizer. Follow with sunscreen in the morning and a nourishing cream at night for optimal barrier support and lasting results.

• Use on cleansed, damp skin to boost absorption
• Layer under moisturizer and SPF for daytime protection
• Pair with gentle exfoliation routines to enhance texture benefits

Who is this for: Dermalogica Circular Hydration Face Serum is suited for anyone seeking a lightweight, effective hydration boost—especially those with dehydrated, combination, normal or dry skin types who want immediate plumpness plus improved hydration over time. It can be integrated into basic or advanced regimens and is appropriate for users looking to support skin barrier function and texture without heavy oils or creams.
