Are microdermabrasion machines worth it?

Conclusion: Microdermabrasion has been shown to be an effective, non-invasive way to improve the appearance of the skin. However, you should talk to your dermatologist before performing microdermabrasion, as there are some medications and skin conditions that can increase skin sensitivity. Home versions won't provide the same level of skin smoothing as a professional treatment, but they can certainly safely offer mild exfoliation benefits.
