Welcome to HealthcareMagic forum,
Excess of facial and body hair can be removed by various methods --depends you want a permanent method or temporary .Facial and body hair can be because of idiopathic reason(i.e. no exact cause) ,to hormonal
(as in Poly-cystic ovary disease ) or thyroid
cases or familial ...rarely it can also be because of some topical creams or oral tablets .Its important to diagnose the cause first .But in your case as you said you have only fine hairs ,that would mean that its not hormonal .
The best of the treatment is lasers which is a permanent treatment (strictly speaking long term) .Laser hair reduction requires multiple sessions at an interval of say 4-6wks.It is safe an effective...but you should go for it only if you have thick or moderately thick hair.Very fine hair may not show good result.Blonde or gray hair also don't respond well to lasers. Result also depends upon which laser machine you are going for.There are three basic types of lasers used --
1) IPL(intense pulse light)
2) Nd:yag laser
3) Diode laser.
The best of the lot is diode laser which is costly but very effective .The worst would be a IPL (which is actually not even a laser),its just a light device.Apart from its low effectiveness it has other disadvantages also like it can lead to burn marks.The probe of laser s big in size ,so its difficult to manipulate in smaller areas,and thus leads to big rectangular burn marks.Many doctors keep this machine as the cost of machine is less as compared to diode laser.Diode laser not only destroys the root of hair which is black but also the stem cells responsible for new growth of hair.
Other methods which i am sure you are aware of are waxing ,threading and bleaching .Selection depends upon which area you want to go for.These are done in beauty parlors.But remember don't take laser treatments from any beauty parlor,prefer a laser clinic run by a dermatologist
. Creams are also available to remove hair but they are esp used for legs and arms and are very temporary.
I hope this would help you decide which technique to go for .
