Why is there a yellow spot on my nail after removing acrylics?

A yellow spot on your nail after removing acrylics is often caused by a bacterial or fungal infection, similar to Green Nail Syndrome. This discoloration typically develops when moisture becomes trapped between the acrylic and the natural nail, creating an environment where bacteria (like Pseudomonas) or fungi can thrive. Other possible causes include nail staining from acrylic products, keratin damage, or early onychomycosis (nail fungus).

Key signs to watch for:

• Yellow, green, or brown discoloration
• Thickening or crumbling of the nail
• Tenderness or foul odor
• Separation of the nail from the nail bed

Because yellow nail discoloration can range from harmless staining to a treatable infection, identifying the cause early matters.
