We are fair-skinned blondes of northern European descent. They are caused by an overproduction of scar tissue and occur at the site of an injury. An operation, vaccination, burn, even a minor scratch or acne can cause them. They are fairly common on black skin and less common on white skin. Your daughter's keloid is harmless, but it may be tender, itchy or displeasing.
Some keloids stop growing or even disappear by themselves.
Surgical removal often causes further scarring unless it is followed by X-ray treatment or injection of steroids at the site. You might give them time to diminish and consult a plastic surgeon if you see no improvement. Your primary care doctor or your dermatologist would be the best source of information about the skin around your eyes. Some white spots in this area are from clogged pores and are called pustules. Keeping the skin clean and free from excessive oil sometimes can reduce them.
