Description
Hydrating serum with hyaluronic acid for long-lasting moisture balance
Dehydrated skin is not the same as dry skin. Dry skin is a skin type: skin that naturally produces too little sebum. Dehydrated skin is a skin condition: moisture deficiency in the skin itself, which can occur in any skin type, including oily skin. The problem is that many people do not realize this and treat their dehydrated skin with heavy creams, while the issue actually lies in continuous moisture loss. Without intervention, the skin remains stuck in a vicious cycle: moisture flows from the deeper skin layers to the outside and evaporates into the air.
Dermalogica Circular Hydration Serum is developed to break exactly this cycle. The formula combines enhanced hyaluronic acid, polyglutamic acid from fermented soy, and an algae complex that addresses moisture on three different levels simultaneously: immediate hydration, replenishing moisture reserves, and preventing future evaporation. Clinical tests show that 97% of users experience more hydration after 20 minutes and 87% still after 10 hours. The 30ml size is the standard size and good for about three months of daily use.
Benefits

- Replenishes the skin's natural moisture reserve thanks to polyglutamic acid
- Balances the skin microbiome with a postbiotic oat complex
- Light gel texture suitable for layering under makeup or moisturizer
Active ingredients
Enhanced hyaluronic acid (Hyaluronic Acid & Sodium Hyaluronate): The formula contains two forms of hyaluronic acid with different molecular weights. The larger hyaluronic acid forms a hydrating film on the skin surface and immediately smooths fine lines. The smaller sodium hyaluronate penetrates the upper skin layers and binds moisture where it is needed. Together, they ensure that hyaluronic acid works both immediately and sustainably.
Polyglutamic acid from fermented soy: A biotechnological ingredient that binds up to four times more moisture than hyaluronic acid, thereby strengthening the skin's natural moisture reserve. Unlike hyaluronic acid, which mainly works on the surface, polyglutamic acid forms a network in the skin that retains moisture for a long time. This is the ingredient responsible for lasting hydration up to 10 hours after application.
Algae complex (Laminaria Digitata, Chondrus Crispus, Gigartina Stellata, Macrocystis Pyrifera & Lithothamnion Calcareum): Five different algae extracts that together form a hydrating matrix. Each algae provides its own combination of minerals, amino acids, and polysaccharides that hydrate and nourish the skin. Brown algae and kelp mainly supply minerals, while red algae contribute polysaccharides that retain moisture in the skin.
Xylitylglucoside (plant-based sugar): A sugar molecule derived from plants that acts as a natural moisture magnet. It binds water molecules to the skin surface and helps prevent moisture evaporation. This is the third layer in the serum’s "circular" action: after hydrating and filling, this step prevents the moisture from escaping again.
Postbiotic complex (Lactobacillus Ferment & Avena Sativa): A combination of fermented lactic acid bacteria and oat extract that supports the natural skin microbiome. A healthy microbiome is essential for a well-functioning skin barrier, which in turn retains moisture better. With daily use, this ingredient builds a more resilient skin that dries out less quickly.
Amino acid complex: A blend of amino acids similar to those naturally found in the skin. These substances are part of the skin’s natural moisturizing factor (NMF), which is often insufficient in dehydrated skin. By supplementing these amino acids externally, the skin’s natural moisture balance is literally restored.
Panthenol (provitamin B5) & Lactic Acid: Panthenol soothes and hydrates simultaneously, helping to restore the skin barrier. A low concentration of lactic acid gently supports natural skin renewal and ensures the skin better absorbs the other active ingredients.
Glycerin, propanediol & butylene glycol: Three humectants that form the base of the formula and bind moisture from the surrounding air. Together they create the carrier system in which the high-tech ingredients can work optimally.

Frequently Asked Questions
How long does the 30ml bottle last approximately?
With twice-daily use of 4 to 6 drops each time, a 30ml bottle lasts about three months. The light gel texture spreads easily, so you need only a small amount per application. With once-daily use, the bottle lasts twice as long.
What is the difference compared to a regular hyaluronic acid serum?
Most hyaluronic acid serums work only superficially and for a few hours. Circular Hydration Serum combines hyaluronic acid with polyglutamic acid, an algae matrix, and plant sugars that together cover the full hydration cycle. Clinical tests show that 87% of users still experience increased hydration after 10 hours, which is not achievable with classic hyaluronic acid alone.
Can I combine this serum with retinol or vitamin C?
Yes. Circular Hydration Serum actually forms an excellent base for routines with active ingredients that stress the skin barrier. First apply Circular Hydration Serum, let it absorb, and then follow with your retinol or vitamin C. The hydration helps improve the skin’s tolerance for these actives.
Does the hyaluronic acid feel sticky?
No. The formula is deliberately developed as a light gel texture that absorbs without a sticky residue. This makes the serum suitable to wear under makeup or as a layer in a more extensive routine without products pilling.
Does this serum also work for oily skin?
Yes, and often surprisingly well for oily skin. Many people with oily skin also have dehydrated skin: the skin produces extra sebum to compensate for the lack of moisture. By providing moisture without adding lipids, sebum production often decreases rather than increases.
When will I see the first results?
Immediately after application, the skin already feels fuller and more hydrated. Clinical tests show that 97% of users experience increased hydration after 20 minutes. For structural results, such as fewer fine lines and a less dull-looking skin, consistent use over four to six weeks is necessary.
Can I use this during pregnancy or breastfeeding?
The formula contains no retinoids or high concentrations of acids that should be avoided during this period. However, it does include essential oils such as bergamot, grapefruit, and sandalwood. If in doubt or if you have sensitive skin during pregnancy, we recommend briefly consulting your midwife.
