are benign skin growths which, by definition, are actually benign tumors of the connective tissue. They look like small soft nodules, and can vary in size from a few millimeters to a centimeter.
They usually are the same color as skin, but can also be brightly pigmented. The changes are not malignant, but throughout life they grow and become more noticeable, therefore becoming an aesthetic problem.
They most commonly appear in middle aged people and especially on places where the skin is rubbing, so usually on the neck, armpits, groin, feet, stomach, eyelids, but can also occur elsewhere on the skin.
They could cause problems as they occur in areas where skin rubs so the spot can become painful- it can become inflamed, start growing, bleeding etc.

The reason for their appearance is still relatively unknown, but the general consensus seems to be that they are hereditary.
Malic acid The good news is that you can remove them without bleeding and scarring, with only one ingredient and that is malic acid.
is a naturally occurring compound found in apples and apple cider vinegar. It has been proven to reduce muscle soreness and pain in people who suffer from fibromyalgia and chronic fatigue syndrome. It has also been shown to be an effective energy booster.
Malic acid is a common additive in skin care products for its exfoliating products. It deeply penetrates skin due to it’s chemical composition.
Note: malic acid should never be used for removal of fibroma of the eyelid!
This method has helped many people. Here’s how:
Carefully wash the place around fibroma with water and mild soap. During the first time soak the fibroma in water for about 15 minutes (or put soaked cotton on it).
Dry it.
Soak a piece of cotton with apple cider vinegar and then squeeze it.
Place it directly on the fibroma and fix it with a plaster or bandage. Leave it for 15 minutes then rinse with water.
Repeat three times a day for several days, up to one week. Fibromas should first become dark, form a crust, dry out and ultimately fall off.
Depending on the fibromas size or how deep it is in the skin, it can cause minor skin damage (a little whole), so marigold grease or Aloe Vera gel should be applied on the skin.
If the fibroma isn’t deep into the skin, there won’t remain a scar -if the procedure is done carefully.
