Colorful Watermelon
Cat Eye Nail Art — Step-by-Step Tutorial

Create vibrant 3D watermelon nails featuring mesmerizing cat eye effects, starry accents, and a glossy glass bead finish with this easy guide.

Steps

1. 1Apply milky white leveling gel

   

   Apply a base coat layer of milky white leveling gel onto the nail surface using a brush. Make sure the application is even to establish a smooth, luminous foundation for the subsequent cat eye layers and detailed nail art.

   Tip: Work with a steady hand to keep the leveling gel even across the entire nail plate.
2. 2Apply boiling water No. 3 cat eye gel

   

   Brush a layer of boiling water No. 3 cat eye gel evenly over the entire nail. This special cat eye formula creates a vibrant shifting metallic effect that serves as the dynamic base for the watermelon design.

   Tip: Apply an even coat so the magnetic particles disperse uniformly before magnetizing.
3. 3Draw wide cat eye beam

   

   Use a magnetic wand to draw a wide cat eye beam from side to side across the nail. Hold the magnet close enough to shift the metallic particles without touching the wet gel surface.

   Tip: Keep the magnet parallel to the nail to create a clean, broad band of light.
4. 4Create glass bead effect

   

   Continue swirling the magnet to shape the cat eye particles into a centralized glass bead effect. This creates a brilliant, multi-dimensional sphere of light that looks super bright and gorgeous on the nail.

   Tip: Gentle circular swirling motions help concentrate the magnetic shimmer right in the center.
5. 5Paint large watermelon shape

   

   Use a fine liner brush with watermelon cat eye gel to paint a large watermelon shape onto the nail surface. This acts as the main fruit segment for the themed nail art design.

   Tip: Outline the shape cleanly before filling it in to maintain sharp, distinct borders.
6. 6Magnetize watermelon gel

   

   Use the magnetic wand to pull and brighten the watermelon cat eye gel into a glowing sphere. Magnetizing this section makes the watermelon element look super bright, clear, and dimensional.

   Tip: Re-magnetize immediately after painting to catch the particles while the gel is still fluid.
7. 7Paint Watermelon Rind Texture

   

   Using a fine detail brush and autumn chrysanthemum green gel, carefully paint the distinct striped texture onto the watermelon rind outline. This adds realistic depth and definition to the fruit design, ensuring the pattern looks structured and vibrant before adding the inner details.

   Tip: Keep your brush strokes light and steady to ensure the stripes remain crisp and evenly spaced.
8. 8Paint decorative elements around the watermelon

   

   Using a fine detail brush and colored gel, carefully paint small decorative patterns, stems, and leaves around the outer perimeter of the watermelon design to enhance the overall aesthetic.

   Tip: Keep your brush strokes light and precise to ensure the details look delicate rather than bulky.
9. 9Add polka dot details

   

   Using a dotting tool, carefully place small, colorful polka dots around the perimeter of the central watermelon design. This playful detail beautifully complements the main artwork and fills in the negative space. Cure the dots fully under your UV or LED lamp before proceeding.

   Tip: Wipe your dotting tool clean before switching colors to ensure the dots remain crisp and bright.
10. 10Apply transparent carving gel

    

    Scoop a generous dollop of transparent carving gel and place it directly onto the center of the nail, right over the watermelon design. This thick, clear gel acts as a magnifying glass to create the signature 3D glass bead effect and gives the nail dimension.

    Tip: Ensure your tools and hands are completely clean so no dust or lint gets trapped inside the clear carving gel.
11. 11Encase design with transparent carving gel

    

    Take a dollop of transparent carving gel, place it onto the nail surface over the completed watermelon art, and gently press and flatten it down to completely cover and encapsulate the entire design, giving it a 3D glass-like dome effect.

    Tip: Ensure the carving gel completely seals the edges of your artwork to prevent lifting and protect the design underneath.
12. 12Apply final sealing top coat

    

    Apply a final layer of smooth, high-gloss top coat over the entire nail surface, sealing all edges and capped areas completely. Cure under the UV/LED lamp to lock in the shine and protect the manicure.

    Tip: Always cap the free edge with top coat to prevent premature chipping and wear.
13. 13Apply cat eye gel

    

    Using a flat gel brush, apply an even layer of clear cat eye gel over the entire surface of the second nail. Ensure the coverage is smooth and extends to the edges without flooding the cuticles. Do not cure this layer yet, as it needs to remain wet for the magnetic effect.

    Tip: Work with a light hand to avoid creating streaks in the cat eye particles.
14. 14Create the glass bead effect

    

    Before curing the cat eye gel, use a magnetic wand to manipulate the magnetic particles. Hover the magnet around the edges of the nail and swirl it gently to push the shimmer into a concentrated, glowing center. This creates a brilliant, dimensional glass bead appearance. Once you are satisfied with the look, cure the nail fully in your lamp.

    Tip: If you dont like the magnetic pattern you created, simply brush over the gel to reset the particles and try again before curing.
15. 15Draw a star motif

    

    Pick up a small amount of yellow gel using a fine detail brush. Carefully paint a four-pointed star in the center or slightly off-center on the nail. Start by painting a small cross, then drag the gel slightly outwards from the center to form thin, sharp points.

    Tip: Keep your detail brush relatively dry—too much gel on the brush can cause the star points to look thick and blobby.
16. 16Add colorful accent dots

    

    Using a small dotting tool, pick up red, green, and white gel colors. Place tiny dots scattered around the yellow star to add playful, festive accents to the design. Vary the size and placement of the dots for a balanced, dynamic look. Cure the nail once the dots are placed.

    Tip: Wipe the dotting tool clean between each color to prevent the gels from mixing and muddying.
17. 17Apply milky white leveling gel

    

    Apply a smooth layer of milky white leveling gel onto the third nail to create an even, opaque base for the upcoming cat eye effect and nail art details. Ensure the application is self-leveled across the surface before curing under the lamp.

    Tip: Allow a few seconds for the leveling gel to self-level naturally before curing to avoid brush marks.
18. 18Apply watermelon cat eye gel

    

    Take a fine brush and apply a layer of watermelon cat eye gel evenly onto the surface of the third nail, preparing the base color for the upcoming magnetic effects and nail art details.

    Tip: Apply in thin, even strokes to ensure smooth leveling and prevent pooling near the edges.
19. 19Create glass bead cat eye effect

    

    Position the magnet close to the wet cat eye gel layer to concentrate the magnetic particles into a glowing, concentrated glass bead highlight in the center of the third nail. Once the desired reflection is achieved, cure immediately under the lamp.

    Tip: Keep your hand steady while holding the magnet to prevent the cat eye beam from shifting before you flash cure.
20. 20Paint star motifs

    

    Using a fine detailing brush, carefully paint a yellow star and a mint green four-pointed star onto the surface of the third nail. Keep the lines clean and crisp to complement the whimsical watermelon and starry theme.

    Tip: Clean your fine liner brush in alcohol between colors to keep the edges of your stars sharp and vibrant.
21. 21Add dot accents and apply top coat

    

    Using a dotting tool, place small surrounding dot accents around the star design. Finish the nail by applying a smooth protective top coat layer and curing it under a UV or LED lamp to lock in the design.

    Tip: Keep dot sizes uniform by loading a consistent amount of product onto the tip of the dotting tool.
22. 22Apply boiling water cat eye and magnetize

    

    Apply a layer of boiling water No. 3 cat eye gel onto the fourth nail. Immediately take a magnetic wand to draw and set a bright central glass bead effect, creating a glowing dimension before curing.

    Tip: Hold the magnet steady close to the surface for a few seconds to sharpen the magnetic reflection line.
23. 23Paint and highlight watermelon shape

    

    Using water-gloss No. 3 gel, paint a large watermelon shape on the nail surface. Use a magnet to activate the reflective particles within the gel so the watermelon shape glows bright and clear.

    Tip: Work carefully with the detailing brush to maintain clean, rounded edges for the watermelon base.
24. 24Outline Watermelon Outer Edge

    

    Using fluid white gel, delicately paint the outer outline framing the watermelon design. This creates a clean boundary and separation between the inner fruit elements and the surrounding clear or milky base.

    Tip: Wipe excess product off your brush to prevent the fluid white gel from bleeding or spreading too thick.
25. 25Add Outer Green Rind Layer, Stems, and Leaves

    

    Using autumn chrysanthemum green gel, paint an additional outer rind layer around the design, and carefully draw small stems and leaves at the top of the watermelon.

    Tip: Keep the strokes delicate to ensure the stems and leaves look natural and proportionate.
26. 26Paint Interior Fruit Flesh

    

    Using high-transparent translucent No. 8 red gel, fill in the interior fruit flesh portion of the watermelon design to give it a juicy, translucent appearance.

    Tip: Apply in a thin layer so the transparency of the red gel allows the layers underneath to subtly show through.
27. 27Add Watermelon Seeds

    

    Dip a fine detailing tool into black tapping gel and gently dot tiny, realistic black watermelon seeds across the pink and red fruit flesh. Distribute them naturally to give the illusion of a freshly sliced watermelon.

    Tip: Use a minimal amount of gel on the tip of your tool to prevent the seeds from looking bulky or smudged.
28. 28Dot Additional Colored Points

    

    Add small colorful dots around the outer edges of the watermelon design to create a playful and festive background effect.

    Tip: Vary the colors slightly to match the dynamic slip and polish shades used throughout the look.
29. 29Create 3D Bubble Dome

    

    Take a dollop of transparent carving gel, place it directly onto the nail surface, and press it flat to completely encapsulate and cover the watermelon design. This builds a smooth, high-gloss 3D bubble dome that magnifies the art underneath.

    Tip: Ensure the carving gel seals completely around all edges to prevent air bubbles and protect the art.
30. 30Apply Final Top Coat

    

    Apply a final layer of smooth, glossy top coat over the entire nail to seal the 3D element and secure all layers. Cure completely under a UV or LED lamp for a brilliant, long-lasting shine.

    Tip: Cap the free edge carefully with top coat to prevent chipping and seal the encapsulation layer.
