Q&A for How to Cover a Black Eye

A black eye normally takes around 14 days to heal completely.

If you mean you have dark circles under your eyes, this is relatively normal and can be a result of dehydration, lack of sleep, or even genetics. If you mean you literally have had bruising around one eye for years, you should consult your doctor.

Use foundation and eye makeup to cover up the scar. When you're not wearing makeup, apply Vaseline. It would be a good idea to talk to a doctor about your slow healing process.

No. The easiest way to reduce swelling would be to place a cold compress on the eye for ten minutes at a time.

A black eye will heal on it's own after a couple weeks, but it may heal faster if you use a cold pack for the first 24 hours and massage the area surrounding the eye. But DO NOT touch the bruise itself.

Put ice on it for a day and sleep well. If it doesn't resolve itself, go to a doctor.

Usually they do not leave permanent scarring unless there is a cut or open wound as well.

Try using a concealer first, blending that very well, and then using a powder foundation over it. Also, if you have setting spray, use that, as it helps ensure your makeup will last.
