Bruised Under Nails After Acrylics: What to Know

Blood trapped beneath the natural nail can look red, purple, brown, or nearly black. Acrylic material can hide the extent of the mark and may also hold pressure against a tender nail. A small, stable bruise after bumping or tight application may settle as the nail grows. Discolouration is not always a bruise, so a changing mark, greenish colour, separation, or discharge deserves a closer look. See more about [Discoloured Nails](/symptoms/nail-discoloration/).

Do not drill, puncture, peel, or force the acrylic off. Avoid another manicure while the area is sore, keep the finger or toe clean and dry, and protect it from knocks. If the overlay is loose, snagging, or painful, have it removed gently by a qualified professional or clinician rather than pulling it. A cool pack wrapped in cloth can help with early swelling. Do not place adhesive over broken skin.

Arrange prompt medical assessment for severe or increasing throbbing, marked swelling, a bent finger or toe, numbness, loss of movement, a deep cut, or bleeding that will not stop. Seek care if redness spreads, warmth and pus develop, or fever occurs. A clinician may need to examine the nail bed and decide whether drainage or [Nail Surgery](/treatments/surgical-dermatology/nail-surgery/) is appropriate.

Could the natural nail or nail bed be torn? Should the acrylic be removed now, and who should remove it? Does the colour fit a bruise or another nail problem? What signs of infection or nail separation should I watch for?
