There are some excellent post treatment products that your skin therapist can and should use after a treatment to minimise the discomfort or redness caused by microdermabrasion.
Some mild flushing with a tingling feeling is normal. Your face can feel progressively tighter for a few days with some superficial dryness ( depending of the depth of treatment performed). Soothing, hydrating post procedure products can really help such as Skinmedica's Ceramide cream or their wonderful CalmPlex Anti Redness cream and Skinceuticals Phyto Corrective Gel - see links below for information
That said - some degree of inflammation is needed as its through this skin healing mechanism that these treatments work. Inflammation is an indicator to the body that repair is needed - a bit like the man from the council highlighting a pothole with spray paint for the repair men to come and fill it in!
The repair in this case is fibroblast stimulation initiating the formation of new collagen for a smoother firmer skin.
Hope that helps
