Adding an iridescent pearl chrome finish over a classic French manicure creates a luminous, glazed donut effect that catches light beautifully. Execute a classic white-and-pink French manicure using gel polish, curing the layers under a UV or LED lamp as directed. Apply a layer of non-wipe gel top coat and cure for thirty seconds until smooth but receptive to pigment powders. Using a silicone applicator or foam sponge tool, gently rub a fine white chrome or pearl iridescent powder across the entire nail surface until a mirror-like sheen develops over both the pink base and white tip. Dust away excess chrome powder with a soft brush, then seal with a final layer of glossy gel top coat to lock in the pearlescent glow.
