Nail Bed, Explained
Quick definition
The skin beneath the nail plate that anchors and nourishes it.
The bed's ridges guide nail growth and its vasculature gives nails their healthy pink. Chronic picking, aggressive gel peeling or injury can shorten its attachment — causing nail separation.
Protecting the bed means protecting the free edge: capped polish ends and gloves for cleaning do more than any strengthener.
Nail bed injury vs infection
| Symptom | Likely injury | Likely infection |
|---|---|---|
| Onset | After crush, slam or aggressive manicure | Gradual over days |
| Pain | Throbbing first 48h, then fades | Persistent, may worsen |
| Colour | Blood blister (dark red-purple) | Green, yellow pus, spreading redness |
| Smell | None | Often present |
Chronic picking and gel peeling shorten nail-bed attachment — see our yellow nails guide if discoloration follows.
