It is advantageous to check the skin for changes and this includes the appearance of existing moles, the key is to know your body and therefore realize when changes occur.
As a child develops sometimes the cells of the skin group together rather than dispersing evenly, this is how a mole is formed.
This can continue as growth continues but stops by the time someone is in their mid twenties. If new growths appear at a later stage they should always be checked out by a doctor.
Most moles are small and fairly insignificant, either brown or black in color. Sometimes however a lot of moles especially on the face can make a person very self conscious.
If this is the case there are several options available to get them treated or in some cases removed altogether.
There are several natural remedies, which can be used at home and that are therefore very inexpensive. By its nature there will be no risk of scarring but often these methods can take long periods of time to produce any obvious results.
Laser treatment is becoming more popular and is known to be very effective. It will sometimes require a series of visits to finally remove the offending moles and it is relatively expensive. It works by a laser beam removing the top layer of skin. Always ensure that the person you choose to perform this treatment is reputable.
Finally there is the option for plastic surgery which will involve the use of anesthetic. This obviously brings its own dangers and should be considered very carefully before going ahead. There is also a slight possibility of scarring taking place.
