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.

Reviews
Could not live without their products
"As a 67-year-old Aging baby boomer, dermatological is the only thing that has managed to keep the clock from showing up on my face. This product in all of their serums are absolutely amazing and an essential part of a simple clear and effective skin care routine for us, older folks.. thank you Dermalogica, well worth the money and the pleasure of your incredible product service support."
— Lillian M. (5/5)
Very refreshing
"Being new to the face care world it can get confusing, but my skin care expert at Hand and Stone highly recommended this product. Now the Circular Hydration Serum is part of my daily routine. The application of the serum is easy and feels so refreshing. I have really seen a boost in the condition of my skin after just a couple of weeks. . Combined with the face cleansing products this serum in the next step before applying the eye cream."
— Andrew P. (5/5)
Light and Hydrating
"So hydrating! I have a good skincare routine but my skin just felt dry and not locking in moisture. I started using this serum and within a few days I could see the difference in hydration! It’s not oily at all or heavy, it melts into the skin easily."
— Zara C. (5/5)
A Must Use
"My tried and true! This serum has transformed my skin from dry to hydrated in the time I have used it. Other products have come and gone but this has been a staple in my routine. It goes on smooth and leaves your skin feeling hydrated and bright."
— Alexandra T. (5/5)
The best moisturizing serum ever!!
"Super moisturizing! I use it twice a day (morning & night) every day & have noticed great results in my skin's appearance! My face tends to be super dry & the city I live in is also very dry, so this serum has been a serious life-changer! The consistency is super lightweight, but it also feels very hydrating. I can't go a day without it; it's truly a staple in my skincare routine! It layers really well with my creams & sunscreen. If you're debating whether to get it or not, look no further!"
— María R. (5/5)
Amazing serum!! Must have. .
"I absolutely love this product! I’ve got mature skin & I find this serum works extremely well for signs of aging. You should start as young as possible to reduce the aging process. It’s hydrating & works great at night & under makeup for daytime use. I wish I would have found this product sooner! It’s at a decent price point for the quality of product you get."
— Donna T. (5/5)
Just what I wanted in a moisturizer
"This product has been a game changer as a facial moisturizer. I prefer using it as my moisturizer directly and don't have to use other products with it to have very moisturized and healthy looking skin. I really like the smooth application that absorbs well. I appreciate it!"
— Gabrielle D. (5/5)

Absorbs quickly into the skin
"Absorbs quickly into the skin so i feel like i have to use a lot to cover my whole face. Very hydrating and tightening. Works well with sensitive skin. Light feel on skin so its not overwhelming or heavy. Doesn't break me out or dry me out. Works well while on tretinoin."
— Cecelia C. (4/5)

— Jennifer B. (5/5)
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
