Stretch marks are scars — the deep skin tore faster than it could grow, and healed in a line. New ones are red or purple and respond best; older silvery ones take longer, but they do respond. At HW Medical Spa we rebuild the tissue underneath: Fractora body for the deepest remodelling, microneedling with BCN cocktails to stimulate collagen more gently, erbium resurfacing to smooth the surface, DMK to improve the skin's quality overall. Book a consultation in Burlington or Mississauga — bring your oldest ones; we've seen them before.
