Kick-start skin’s hydration cycle: long-lasting serum immediately floods skin with hydration, replenishes from within, and helps prevent future hydration evaporation. Full-circle hydrating serum utilizes an enhanced form of Hyaluronic Acid to penetrate skin’s surface for deep hydration and more supple, radiant skin over time. An Algae Extract-infused moisturizing matrix delivers quick and long-lasting hydration. Polyglutamic Acid from fermented Soy replenishes skin’s hydration reserves from within. Plant-derived sugars and a blend of amino acids similar to those naturally present in the skin trap water on skin’s surface to help prevent future hydration evaporation. A postbiotic blend of Lactobacillus Ferment and Avena Extract helps to balance skin’s microbiome.

Q&A
Every time I incorporate this into my skincare routine, everything on top of it (moisturizer and sunscreen) pills like crazy. What am I doing wrong? What causes the pilling? It leaves my sunscreen chunky and sticky. Thanks
Hi Michelle! Thank you for reaching out to Dermalogica. We'd like to help you with your routine. In order to best assist you, may you please respond to this email with the list of the products you are currently using to care for your skin daily? We look forward to hearing from you! Kind Regards, Beatriz.
Hello. I keep this in my beauty fridge. Is that OK - cold storage?
Hello Carla, Thank you for reaching out to Dermalogica. Yes, it is okay to store your circular hydration serum in your fridge! Kind Regards Willow Dermalogica Professional Skin Therapist
Can I use this as a daytime serum and the Dermalogica retinol serum at night?
Hi there! Yes, you can absolutely do that! Kind Regards, Beatriz.
Is this product gluten free?
Hello, Thank you for your question and interest in Dermalogica. Although there is no standard for establishing a gluten-free designation for topical skin care products, independent laboratory testing confirms that all Dermalogica products surpass the US FDA (Food and Drug Administration) ingestible standards and can therefore be considered gluten-free. Kind Regards, Melissa Virtual Professional Skin Therapist
Would it be redundant to use this with the hyaluronic ceramide mist or more beneficial?
Hello Jenna, You definitely may use these two products together, as the hyaluronic ceramide mist would be your toner step, then you would follow that with the circular hydration serum! These would work great together to ensure optimal product absorption and hydration! Please make sure to then follow with your skin specific moisturizer and SPF if using during the daytime! Kind Regards, Willow Virtual Professional Skin Therapist
