The liquid detergent dispenser is not suitable for gel because the dispenser is designed to dispense liquid detergent, which has a different consistency and viscosity compared to gel detergent. The gel detergent may clog the dispenser or not dispense properly, leading to a mess and potential damage to the dispenser. Additionally, the dispenser may not be able to accurately measure and dispense the correct amount of gel detergent, leading to inefficient use of the product. Therefore, it is best to use gel detergent as directed on the packaging, rather than trying to use it in a liquid detergent dispenser. **

To use gel nail building gel, start by prepping your nails by pushing back cuticles and lightly buffing the surface. Apply a thin layer of base coat and cure it under a UV or LED lamp. Next, apply a thin layer of the building gel, making sure to cap the free edge of the nail. Cure this layer under the lamp, and repeat with additional layers as needed for the desired thickness. Finish with a top coat, cure, and then wipe off the sticky residue with alcohol. **

Just make sure to follow the manufacturer's instructions for application and curing times for each gel product. **
