Too little initiator may ...

• A. It will cause immediate curing.
• B. It increases brittleness.
• C. It may weaken the enhancement or cause an allergic reaction.
• D. It will not affect the final result.

Answer: (C)

Initiator starts the polymerization that hardens the nail enhancement when it’s activated by light or heat. If there’s too little initiator, not enough reaction starter is present to drive all the monomers to cross‑link fully, so the cure is incomplete. That creates a weaker, under‑cured layer that can chip, lift, or wear poorly. Incomplete curing also means more unreacted monomer can remain in the film, which can irritate the skin or trigger an allergic reaction in sensitive clients. So, the final result is weaker strength with a higher risk of sensitivity, rather than an immediate, full cure or a straightforward increase in brittleness.
