Sodium Hyaluronate Crosspolymer
Sodium Hyaluronate Crosspolymer is a high-tech form of hyaluronic acid used in UK skincare and beauty products. It acts like a moisture magnet, holding up to 1000 times its weight in water to keep skin plump and hydrated for longer than regular hyaluronic acid.
How it works in skincare
In cosmetics and skincare, Sodium Hyaluronate Crosspolymer is a cross-linked version of sodium hyaluronate that forms a breathable, invisible film on the skin. This network helps to lock in moisture while allowing the skin to breathe, delivering sustained hydration throughout the day without the tacky feel sometimes associated with traditional hyaluronic acid. It is commonly found in serums, moisturisers, sheet masks and eye creams, where it improves texture and supports a smoother, more supple appearance.

Where it comes from
Although originally derived from the fermentation of glucose using bacteria, the resulting hyaluronic acid is nature-identical and vegan-friendly. It is not extracted from animal sources such as rooster combs in modern cosmetic grades.
