Let me start off by saying I have never tried any other type of microdermabrasoin kit so I can't do a comparison, this is just a review from my point of view after using this product.
I purchased this about 2 weeks ago from Walmart for about $25 and have been using it twice a week. It claims to diminish the look of fine lines and wrinkles and reveal smoother, softer and more even-toned skin. I can say that the look and feel of my skin has improved since using. My skin feels softer and smoother and also looks more radiant. I have read some reviews where people have claimed that their pores look smaller...so far I don't see a change in my pores but I'm hoping to have the same results! (the pores on my cheeks next to my nose are on the larger side).
This is a great product for the price. If anyone else is interested in trying microdermabrasion but don't want to spend a handful of money, give this a go and see how it works for you! Spend the extra money on a new lipstick or a cute pair of shoes! ;-)
