This is my first experience with dermabrasion and I haven't had a salon treatment so I can't compare, but this kit has exceeded my expectations by far.
On a clean face you apply the creme with the crystals who are very, very fine. Then you use the rotating sponge for a few minutes per spot, I do my face and part of my cleavage as those are the places where I have the most sundamage in freckles and hyperpigmentation. It is absolutely painless and easy to do. After you finish with the sponge application you much wipe away the rest of the crystals and the dead skin cells with a dry cloth and then rinse with water. After the very first time I could see that my skin was so much lighter, smoother and best of all the elevated hyperpigmentation spots were gone, seriously gone! The alphahydroxy creme is an extra help, but I am not too fond of the smell, but that disappears when the creme absorps in the skin.
As blackheads and acne is concerned, those will be more longtermed benefits, I presume, but since I have only been using it for 3 weeks I can't comment too much on that part. However I do notice a slight decrease in the pores on my cheeks and nose, so I am optimistic about the rest as well.
Pro's: it works and is very easy
cons: a little pricy, the potions & sponges need to be replaced quite quickly (the crystals are almost halve gone, but I use it 2-3 per week on myself and my mom);
Overall a great product!
