Bruised nail from fake nails: what to know

Acrylic, gel, tips, and other enhancements can add leverage to the natural nail. A bump may pull the enhancement and the nail plate in different directions, irritating the nail bed or causing blood to collect beneath it. Tight application, a lifted edge, or forceful filing and removal can also injure the surface and surrounding skin. A dark mark may be old blood, but green or yellow colour, dampness, or odour suggests another problem should be considered. See [Discoloured Nails](/symptoms/nail-discoloration/) for broader causes of nail colour changes.

Stop applying products over the affected nail and protect it from catching on fabric. Do not pry, peel, clip, or drill off a firmly attached enhancement, because this can strip the natural nail or reopen the nail bed. If removal is needed, use a trained nail professional or clinician who can see whether the natural nail is lifting. Keep any exposed skin clean and dry, and use a light dressing for protection. Cool the finger briefly through cloth if it is swollen. A clinician can discuss specialist options through [Nail Surgery](/treatments/surgical-dermatology/nail-surgery/).

Seek prompt assessment for strong throbbing pain, a nail or tip that is visibly bent, an enhancement that is pulling the nail away, bleeding, numbness, or a cold or pale fingertip. Arrange care if redness, warmth, swelling, pus, or odour develops beneath or around the enhancement. Do not cover a suspected infection with another set of nails. A bruise without a remembered injury, or a mark that does not grow toward the nail edge, also deserves review.

Ask whether the enhancement should be removed now, whether the natural nail bed is exposed, and how to protect the finger during regrowth. Clarify when cosmetic products may be used again and which signs would mean infection or deeper injury.
