What is Hydrogel and what does it do?

Hydrogels are also artificial, however, some of them come from natural sources.


Some sheet masks are made of hydrogel, a thick, translucent polymer material that is noted for its snug fit and water-binding properties. Learn more about Hydrogel with the help of this article.

What is Hydrogel?

A crosslinked hydrophilic polymer known as a hydrogel is very absorbent while maintaining well-defined structural characteristics. Several applications are supported by these qualities. Hydrogels are also artificial, however, some of them come from natural sources.

Physical, chemical, or biological hydrogels are all possible. Physical gels can change from a liquid to a gel state. It happens as a result of a change in the environment’s temperature, ionic concentration, pH, or other factors such as the mixing of two components. Covalent bonding in chemical gels adds mechanical integrity, and degradation resistance, and In biochemical hydrogels, the gelation process is aided by biological components like enzymes or amino acids.

What does it do?

Medical devices can use hydrogels in a variety of ways, and the advantages of doing so have been thoroughly studied. Thin dressings are made possible by the hydrogels’ capacity to absorb water up to many times their weight, and hydrogels that have been synthesised with a high internal moisture content can act as moisture regulators by maintaining a moist environment for dry or burned skin for extended periods of time. High moisture hydrogels can also provide a soft, adaptable layer that can be applied to even challenging places of the body, as well as a cooling effect against the skin.
Additionally, because of their inherent flexibility and softness, they can be used in abrasive environments like foot care.
