Annotation: The article provides an in-depth analysis of the photopolymerization of gel materials, focusing on the influence of UV/LED lamp parameters on the chemical completeness of curing. Particular attention is paid to how insufficient irradiance, uneven light distribution, and mismatch between the spectral output of the lamp and the absorption range of photoinitiators (365–405 nm) lead to the formation of layers with a low degree of monomer conversion. It is shown that such polymerization defects promote the accumulation of residual monomers, which can penetrate through the nail plate or come into contact with the skin, increasing the risk of allergic sensitization in technicians and clients. The study also includes a technical comparison of inexpensive and professional lamps, including an assessment of diode types, power stability, cooling quality, and the ability to ensure sufficient polymerization depth. The results demonstrate that a scientifically grounded selection of a lamp is a key factor in ensuring safe and complete curing of gel systems.
