Common Defects in UV Gel Nail Polish (9)

Common Defects in UV Gel Nail Polish (9)

During the application of UV gel polish, edge lifting is an early sign of chipping. It begins at the nail’s leading or lateral edges, where small gaps or lifted margins first appear; if left unaddressed, these defects will gradually expand until the entire layer eventually flakes off. Unlike full-layer delamination, edge lifting has a distinct starting point and a predictable pattern of progression. Understanding the underlying causes of edge lifting can help you implement targeted preventive measures during use.

During the application of UV gel polish, the presence of particles is one of the most common issues affecting surface smoothness. After curing, the gel polish develops tiny raised bumps on the surface, which feel noticeably rough to the touch and appear as a speckled, pitted texture. Unlike defects such as brush marks or wrinkling—which are typically caused by application technique—particle formation is more closely linked to external environmental factors and the cleanliness of the product itself.

During the application of UV gel polish, brush marks are one of the common issues that affect surface smoothness. After curing, these marks leave distinct brush-bristle impressions on the surface, resembling narrow, elongated grooves that detract from the natural, polished finish of the nail. Unlike defects such as wrinkling or bubbling, brush marks are more closely related to the ease of application and the product’s flow characteristics.

During the application of UV gel polish, incomplete curing is one of the factors that can compromise coating performance. When cured incompletely, the surface of the gel polish remains tacky after irradiation and shows fingerprint marks, or the interior of the coating remains liquid, preventing the formation of a hard, intact film. Unlike surface defects such as wrinkling and shrinkage, incomplete curing means that the product’s fundamental performance is not fully realized. Understanding the causes of incomplete curing can help users consciously avoid this issue during application.

During the application of UV gel nail polish, yellowing is one of the common quality issues affecting light-colored and transparent products. Yellowing manifests as a yellowish tint appearing in the originally clear or light-colored coating after curing or following a period of use—white turns off-white, and clear becomes pale yellow—severely compromising the visual appeal of the manicure. Unlike physical defects such as wrinkling or chipping, yellowing is a chemical aging phenomenon. Understanding the root causes of yellowing can help users consciously avoid this issue during both application and storage.

During the application of UV gel polish, chipping is one of the key factors that affect the longevity of a manicure. Chipping manifests as the gel lifting at the nail edges or peeling off entirely from the nail surface, causing the manicure to lose its integrity in a short period of time. Unlike surface defects such as wrinkling or shrinkage, chipping is directly related to the adhesion performance of the coating and is therefore a particularly sensitive complaint among users. Understanding the root causes of chipping can help practitioners take targeted measures during application to prevent this issue.

During the application of UV gel polish, bubbling is one of the more common defects. Bubbling manifests as round air bubbles of varying sizes on the surface after the gel has cured—some small and densely packed, others large and conspicuous—significantly compromising the aesthetic appeal and coating integrity of the manicure. Unlike wrinkling or shrinkage, bubbling is more closely related to application technique and the condition of the nail surface. Understanding the causes of bubbling can help practitioners consciously prevent this issue during the process.
