Which chemical reacts with resins and proper curing lamps to cure UV gel?

The correct answer is the photo-initiator. This chemical plays a crucial role in the curing process of UV gel. When UV light is applied, the photo-initiator absorbs this light energy, which triggers a photochemical reaction that leads to the polymerization of the resin in the gel. This process transforms the liquid gel into a solid, durable layer on the nails, providing strength and a glossy finish that is essential in nail enhancements.

In the context of gel products, the effectiveness of the photo-initiator is vital, as it determines how quickly and efficiently the gel will cure when exposed to the appropriate wavelength of UV light. Understanding the role of photo-initiators helps nail technicians ensure that they achieve the best results when applying UV gel, allowing for longer-lasting nail enhancements and overall client satisfaction with their manicures or nail art.

Other options such as thinner, stabilizer, and hardener serve different purposes and do not have the same function as photo-initiators in the curing process of UV gels. Thinner is used to modify the viscosity of a product, stabilizers help maintain the formulation's consistency, and hardeners are often used to enhance the toughness of various materials, but none are directly involved in the curing reaction triggered by
