Handling Poor Conditions in UV Gel Nail Polish (Part 8)


Granulation refers to the formation of tiny raised bumps on the cured surface of gel polish, which feel rough to the touch. This issue is primarily caused by external environmental contamination and internal product contamination. Unlike defects such as brush marks and wrinkling, which are often attributable to application technique, granulation is more closely linked to environmental cleanliness and proper product maintenance. This article will discuss strategies for preventing granulation as well as methods for addressing it once it occurs.

Handling Poor Conditions in UV Gel Nail Polish (Part 7)


Brush marks refer to conspicuous brush-bristle impressions left on the surface of cured gel polish, which compromise smoothness and gloss. This issue is closely linked to the product’s flow properties and application technique. Unlike chemical problems such as incomplete curing or yellowing, brush marks are primarily physical surface defects. This article will discuss strategies for preventing brush marks and methods for addressing them after they occur.

Handling Poor Conditions in UV Gel Nail Polish (Part 6)


Insufficient curing refers to a situation where the gel polish remains sticky on the surface or retains a liquid consistency internally after curing.

Proper curing is the foundation for all performance characteristics; insufficient curing, however, renders the coating unusable. This article will discuss strategies for addressing insufficient curing from two perspectives: preventive measures and post‑curing remediation.
