The Dermalogica Circular Hydration Serum is designed around a continuous hydration approach. It doesn’t just add moisture once and stop. It works to replenish water and slow the rate at which your skin loses it, so the effect lasts all day and night.
The serum uses a multi-weight hyaluronic acid system. Hyaluronic acid of different molecular weights acts at different depths of the stratum corneum. Larger molecules are close to the surface and retain moisture there. Smaller molecules penetrate deeper and bind water further down. Together they give your skin layered, long-lasting hydration instead of a quick surface treatment.
It is too fragrance-freewhich is important in winter. When your barrier is already stressed by cold air and heating, fragrance can be the thing that irritates sensitive or reactive skin. The Circular Hydration Serum is gentle enough for skin that’s currently feeling reactive, without sacrificing results.
Customers describe skin that feels plumper and dry patches that ease with consistent use. And that comfortable, secure feeling that lasts all night long. It is suitable for normal, dry and dehydrated skin, making it suitable for most people reading this.
