I have had microdermabrasion 3 times. I think it is one of the most effective ways of treating the skin because it is gentle yet you see good results. It is basically a sanding of the skin, little crystals are shot through a wand that they rub over your face...it doesnt really hurt, and afterwards you have a great healthy glow.... You see the best reults after a few weeks. I always get compliments on my skin after... this treatment is best when you dont have any whiteheads... it is better for reducing pore size and reducing scars... For more active Acne glycolic peels or aha peels would be much better.
