In London, Ontario, effective acne scar treatments include: microneedling (often with PRP) to stimulate collagen; fractional and ablative lasers (CO₂, erbium) for deeper scars; chemical peels like TCA and PRX‑T33 to resurface skin; subcision and dermal fillers for depressed (atrophic) scars; and consistent medical‑grade skincare. https://lite.evernote.com/note/6ea0d6a7-a58c-0152-16b8-764d521a38f3
