How effective are they???
From what I heard about it, They are effective but when done several times. I cant recall how many treatments were adviced, but ofcourse that differs from patient to patient 
One treatment wont make mutch difference though 
And it works for peeple with minor skin issues. 
Any home kits can only work to a certain point, and the microdermabrasion kits that I have seen seem very tough exfoliators. Which kit are you particularly interested in Sajal? Have you compared the cost of the home kit versus the salon treatment, sometimes the home option isn't as money or time saving as you'd imagine.
I was interested in one by Loreal'.
It was only around $22, verses the salon treatment which can
cost up to a 1000 bucks.
SAJAL i've seen so many ladies get into the cycle of peelings and dermabrasions and regular facials and oxygen treatments and i dono what else...
is this stuff really good for your skin? plus it seems like an endless cycle and once you get into the habit you cant stop...plus its costly...
why dont u try more natural methods like desi nuskhay and masks...dont you think they will be more healthy for the skin?
just a thought :)
