Microderm is something that I've been considering for a while. It's one of the less expensive cosmetic procedures, and it can literally be performed during a lunch hour (probably why it's often called a "lunchtime peel"). And, best of all, there's very little recovery time needed--the only real side effects are slight irritation and redness, which typically subside in about 24 hours.
So, what does it do? Basically, a device that resembles a sandblaster sprays small crystals that exfoliate the top layer of dead, dull skin cells. This process has many benefits. In removing these skin cells, microderm clears pores and prevents breakouts in people with acneic skin. For those with mature skin, microderm can enhance collagen production for smoother skin, while also minimizing fine lines and age spots. Sounds good to me!
But, it doesn't help with problems that go deeper than the top layer of skin: think scars, stretch marks or deep wrinkles.
Have you tried microderm? What did you think? What skin conditions were you attempting to correct?
