Chemistry & ProductsQuestion 82 of 100
You cure a client's gel in a lamp that was not made for that gel line. Within a week the gel is lifting at the edges and she says her fingertips itch. What is the most likely cause?
a.The photoinitiators in the gel never received the wavelength and lamp output they need, so the coating stayed under-cured — under-cured gel lifts and the uncured chemical on the skin can cause sensitization.
b.The gel was cured too thoroughly, which always makes gel brittle and makes it peel off in a week.
c.Gel does not really need a lamp; the lifting comes from the base coat alone and the itching is unrelated to the product.
d.Lifting and itching together prove that the client is allergic to acetone.
Explanation
UV/LED gel only polymerizes when its photoinitiators are struck by the correct wavelength and intensity, so the wrong lamp leaves the coating partly liquid inside. Under-cured gel bonds poorly and lifts, and the uncured ingredients that reach the skin are exactly what drives allergic sensitization. Over-curing is not what caused this, gel absolutely does require a matched lamp, and acetone was not part of this service.
