Can one remove stretch marks using chemical peels / microdermabrasion?

Improve not remove. Yes, these interventions could improve stretch marks. Laser and retinoids may also provide some relief. However do not expect complete removal.
Remove-NO; Improve. But the degree of improvement is usually minimal at best, even by the most aggressive or technologically-advanced techniques. Lots of fly-by-night methods exist, right beside the "real ones" which themselves are pretty unremarkable--that's why there are so many of them, and why so many gullible patients want to "try" anything out there. Surgical tummy tuck removes them from pubis to belly button!
