Polymerization in gel polish is a chemical process that occurs when the gel polish is exposed to UV or LED light. The gel polish contains monomers and oligomers that, when exposed to the light, crosslink with each other to form long chains of polymers.
During the polymerization process, the gel polish transforms from a liquid or gel-like state into a solid, durable and glossy coating that adheres to the nails. The polymerization process allows the gel polish to cure quickly and create a strong bond with the natural nail.
Once the polymerization process is complete, the gel polish becomes resistant to chipping, cracking and peeling, and can last for several weeks without the need for touch-ups. This makes it a popular choice for people looking for a long-lasting and low-maintenance manicure.
