No. Striae extend through the full thickness of the skin (epidermis plus dermis) and microdermabrasion is only intended to treat the epidermis.
Microdermabrasion . Microdermabrasion is not helpful for stretch marks. It is a superficial removal of the epidermis. Stretch marks are caused by the dermis (second layer of skin) stretching out and being thinner. The best treatments are Retin-A or laser, although no treatment is really that remarkably effective. Time will fade most stretch marks, thankfully. I hope that helps!
