Dreaming of shimmering, ocean-inspired nails? The mermaid effect - a magical, iridescent finish that shifts in the light - is a summer favourite that turns any manicure into a sparkling statement. The best part? You can achieve this look yourself, right at home, using UV gel polish and a special powder.
Here’s a step-by-step guide to help you get that glamorous, underwater glow without a salon visit.
What You’ll Need:
-
UV gel polish (ideally in white, pastel, or light shades for maximum effect)
-
A soft applicator (sponge, eyeshadow applicator, or silicone tool)
-
Clean-up brush or dusting brush
Step-by-Step: Mermaid Effect with UV Gel Polish

Step 1: Prep Your Nails
Start with clean, shaped nails. Gently push back your cuticles, buff the nail plate, and clean away any dust or oils. Apply a thin layer of base coat and cure it under a UV/LED lamp.
Step 2: Apply Your Colour
Choose a light base colour - white, soft pink, baby blue, or pale lavender work beautifully. Apply 1–2 thin coats, curing each layer. Make sure the surface is smooth and even.
Step 3: Apply a No-Wipe Top Coat
For the mermaid powder to stick properly, apply a layer of no-wipe top coat and cure it fully. The powder needs a smooth, slightly tack-free surface to adhere correctly.
Step 4: Rub in the Mermaid Powder
Using your applicator tool, gently rub the mermaid powder into the nail surface. Work in circular motions to ensure a uniform, shimmering finish. Watch the magic happen as the light catches the iridescent effect.
Step 5: Seal the Look
Brush off any excess powder, then apply another layer of top coat to seal in the effect. Cure one final time under the UV/LED lamp.

Tips for the Best Mermaid Finish
-
Smooth application is key - any bumps or uneven patches will be more visible under the powder.
-
Use light colours - the mermaid effect pops best against pale or pastel UV gel polishes.
-
Avoid too much powder - a little goes a long way. Applying too much can dull the shine.
