Undercured Gel Polish What and Why

One problem people may have with gel manicure is undercuring. It shows when the polish is still sticky after curing and wiping. Undercuring will increase the risk of service breakdown and may increase the risk of an allergy to any gel product.

Potential Causes & Solutions

• Improper hand placement –> Hands and nails should be properly placed far enough under UV or LED bulbs
• Gel has been applied too thickly –> Apply thin layers. Shake nail polish well before application. Cure each layer separately and cure according to the recommended time by the manufacturer.
• Not using CND UV Lamp –> Shellac was developed to be fully cured using Shellac lamp. Using different lamp may cause Shellac is not fully cured.
• Bulbs need to be replaced –> Recommended time to replace all bulbs is 6 months or when it shows signs of undercuring.
• Incorrect removal of tacky layer or use acetone or diluted Isopropyl Alcohol –> Use 99% Isopropyl Alcohol to remove sticky layer.
