What is the function of spray-on activator in no-light gels?

• A. To add shine
• B. To harden the adhesive
• C. To strengthen the nail
• D. To remove residue

Answer: (B)

The function of spray-on activator in no-light gels is to harden the adhesive. This activator is a crucial component in the curing process of no-light gel systems. When applied, it triggers a chemical reaction that causes the gel to solidify rapidly without the need for a UV or LED light. This allows nail technicians to effectively shape and apply the no-light gel to the nails, resulting in a durable and long-lasting finish.

Understanding this process highlights the importance of the activator, differentiating it from other potential functions such as adding shine, strengthening the nail, or removing residue, which are not the primary purposes of the spray-on activator in this context.
