Semi-permanent nail polish does not harden? This problem happens more often than we think and can affect both beginners and professionals. Understanding why the product does not cure properly is essential to achieve a successful application and enjoy a long-lasting, shiny manicure.
Semi-permanent nail polish does not harden: the main causes
The first cause is a UV or LED lamp that is too weak, unsuitable, or improperly used. Another explanation is the application of a layer that is too thick: the light does not reach all layers of the product. Finally, the quality of the nail polish plays a key role: an expired or non-compliant product can cause problems.
To prevent semi-permanent nail polish from not hardening, apply thin layers, use a high-performance lamp, and always choose certified and reliable products.
