1.Pre-Preparation Use a nail file to trim the shape of your nails (square/round/almond shaped, etc.). Soften and clean dead skin, wipe nail surface with alcohol cotton pads to remove oil and dirt. 2.Apply Base Gel Apply a thin layer of base gel, avoiding contact with skin. Shine the light for 60 seconds until fully cured. 3. First coat of cat eye glue Apply a thin layer of Cat's Eye Nail Polish (color of your choice) without shining the light. Immediately apply a magnet stick parallel to the nail surface (2-3mm distance) and hold for 5-10 seconds to form a light band. Quickly shine the light for 60 seconds to cure. 4. Second layer of reinforcement Repeat step 3 with another coat of Cat's Eye Gel and use a magnet to draw out the effect. Light for 60 seconds (more saturated color and more visible light bands). 5. Sealer Apply no-rinse sealer, making sure to cover all areas. Light for 120 seconds to cure thoroughly. 6.Clean Nail Surface Wipe nail surface with cleaning solution or alcohol to remove any floating gel residue. Advanced Tip: Wide cat's eye effect: move the magnet slowly parallel to the nail surface. Fine cat-eye effect: tilt the magnet 45 degrees to stay close to the nail surface. Gradient cat's eye: apply the base color first, then use the magnet to suck out the light band in the local area. Caution: The magnet should stay long enough, otherwise the light band will disappear. Each layer of nail polish must be coated thinly, too thick to affect the effect. Keep your hand steady during the operation, avoid shaking which will cause blurring of the light band. Nail Removal Method: Use professional nail polish remover or sanding machine to remove the nail polish, do not force to peel.
