If you don't have an existing skin condition that you want to get rid of, ie. scars or fine lines, any type of peel or microdermabrasion will only temporarily change your skin; it certainly doesn't change your skin type and the various problems associated with that skin type. What exactly is it about your skin that you don't like? You might also want to look at non-ablasive laser treatments like Smoothbeam - they are more expensive at $200-$500 per session and require multiple treatments, but they are known to have long term and significant effects on your skin. I know someone who used to have a host of skin problems due to excessive oiliness, and after 3 or 4 smoothbeam treatments her skin was finally under control and not oily at all. Ask your dermatologist or google for details. On the other hand, if you have shallow scars or pigmented blemishes, microdermabrasion works really well. The actual results depend on the aggressiveness setting you and your dermatologist (or aesthetician) decide on; the gentler the procedure, the less drastic the results with a much faster healing time (or virtually no healing time). I had one done a few months ago that was quite aggressive and it took me a good week or so to fully recover (skin was first red and irritated and then started to peel), but the end result was quite remarkable. I've never had a chemical peel done at a dermatologist's offic, but I've heard from a lot of people in the know that it's not worth it since a lot of the same supplies are now readily available on the market and are quite safe to use at home. I've been using a 20% glycolic acid peel and it works pretty much like microdermabrasion, and you can control the extent of the peel yourself by timing the procedure. I just bought another type of chemical peel called TCA online, and it's supposed to be even more effective than glycolic acids, and was exclusively sold to professional aestheticians and dermatologists until very recently. Can't wait to try it.
