Determining whether nail tools need replacement mainly depends on their wear, malfunction, and hygiene. Timely replacement ensures safe operation and optimal nail art results.
Core Judgment Criteria
Worn Files or Buffing Heads: If the nail file surface shows obvious bumps, scratches, or has lost its abrasive feel, causing slippage or decreased efficiency during buffing, it is ineffective and needs immediate replacement.
Deformed or Loose Pliers: If the jaws of cuticle scissors or nail clippers cannot close tightly, or if the handles are loose or cracked, it not only affects trimming accuracy but may also pinch the skin.
Dull or Rusty Blades: If nail scissors or nail clippers become dull, chipped, or rusty after use, it increases the risk of pulling and damaging nails; they should be discontinued and replaced.
Discolored or Ineffective Polishing Strips: When the polishing strip's color changes from dark to light and its surface becomes smooth and lacks a abrasive feel, it indicates that the friction layer has been depleted and it can no longer effectively polish; it must be replaced.
Aging Brushes: Split, falling, or deformed bristles on nail art brushes affect the smoothness of the strokes; uneven or broken bristles on electric brushes can lead to uneven glue application, requiring immediate replacement.
Damaged Handles or Connectors: Cracked handles, loose screws, or loose locking mechanisms on electric polishers pose a risk of detachment during use; these should be stopped immediately and the brushes replaced.
