Smooth skin is like freshly frosted birthday cake: it looks so delicious that no one cares how old you are. Flaunt face cakes with today's Groupon: for $49, you get a diamond-tipped microdermabrasion at Transformations Medi Spa in Waterloo (a $105 value).

Transformations Medi Spa specializes in noninvasive beauty enhancements under physician supervision. The microdermabrasion sloughs off faces’ superficial cell layer and stubborn clown makeup, revivifying skin with an abrasive wand encrusted in tiny diamond particles. As the powerful exfoliation purges the topmost dull skin, it may help evoke a softer, smoother appearance and combat superficial aberrations, including fine lines and age spots. Transformations prides itself on delivering services that require minimal downtime, so patients can quickly get back to daily chores or jobs blogging about daily chores.
