The only 3 professional hair removal systems are waxing which is semi permanent,or electroylosis or laser.
The latter 2 are effective in being more permanent,although regular sessions in the salon are a pre requisite to gain maximum results.
Having said that if budget is an isuue i would opt for waxing.Its semi permanent,and should not grow back for at least 4 weeks,the hair should be finer in texture,but results vary.
I would reccommend a visit to the salon to have this done professionally as opposed to home waxing as results could be disappointing and could be disastrous!
I have not heard of creams to take off hair,if so im sure there are chemicals that could cause irritation and may cause sensitivity.
