Dermalogica Circular Hydration Face Serum 0.34 fl oz — Hyaluronic Acid, 10+ Hour Hydration

This serum is formulated to revive and support the skin’s natural hydration cycle using multiple humectants, moisture-binding polymers, and skin-friendly actives. Designed for daily use under moisturizer or as the central step in a minimal routine, it helps replenish lost moisture, smooth texture, and maintain a more resilient surface without heavy residue. The 0.34 fl oz size is travel-friendly and concentrated for targeted application.

How quickly will I notice hydration after applying the serum?

You should feel an immediate dewy, plumped sensation as the lightweight formula absorbs. The combination of low- and high-molecular-weight hyaluronic acid draws water into multiple skin layers while other ingredients help retain that moisture for extended hours.

• Immediate surface hydration and visible plumping within minutes.
• Formulated to maintain hydration for 10+ hours with regular use.
• Suitable for layering under SPF or night creams without pilling.

What active ingredients make this serum effective?

Multiple types of hyaluronic acid are paired with polyglutamic acid, algae extract, and a postbiotic blend to support both moisture retention and skin comfort. A gentle lactic acid helps refine texture and brighten the complexion through mild exfoliation.

• Enhanced hyaluronic acid delivers multi-depth hydration.
• Polyglutamic acid and algae extract help lock moisture into the surface.
• Postbiotics support a balanced skin microbiome for healthier-feeling skin.
• Lactic acid provides subtle smoothing and radiance without harsh irritation.

Can I use this serum with other skincare products and how?

This serum works well in most routines—apply it after cleansing and toning, then follow with moisturizer and sunscreen in the morning. Because it’s lightweight and non-greasy, it layers smoothly beneath heavier creams or makeup without losing efficacy.

• Apply 2–3 drops to damp skin for best absorption.
• Follow with a moisturizer to seal hydration, and SPF during daytime.
• Compatible with most actives; introduce gradually if combining with strong exfoliants.

Is this serum suitable for sensitive or acne-prone skin?

The formula focuses on hydration and gentle exfoliation rather than harsh actives, and includes a postbiotic blend to help support the skin’s natural defenses. Patch-test if you have very reactive skin, and use lactic acid-containing products sparingly if you experience irritation from alpha hydroxy acids.

• Postbiotic ingredients aim to support barrier comfort and balance.
• Gentle lactic acid concentration designed for mild resurfacing, not aggressive peeling.
• Non-heavy texture reduces risk of pore-clogging when used as directed.

Who is this for: Dermalogica Circular Hydration Face Serum is ideal for anyone seeking a concentrated, travel-sized solution to revive dehydrated, dull, or uneven-textured skin. It suits daily users looking to boost moisture retention, people layering skincare in multi-step routines, and travelers who need an effective, compact serum to maintain hydration on the go. Avoid if you are allergic to any listed actives; consult ingredient details before use.
